morning

yo

how's it going

hi jottinger

just had a massive lunch. feeling tired

what's the good word?

there are no good words, they're all bad

forever the optimist

don't you deal in words?

yes. That's how I know.

you thinking of microsoft

lol

hi jottinger

hey

anyone here use compiz/beryl and swing apps?

hows it going!
~tell man_in_ltop about anyone

man_in_ltop, Instead of asking whether anyone works with something you need help with, please save time by asking your actual question. If someone knows and wants/has time to help, perhaps he/she will.

where would you store an image?

for what?

for storage, no doubt

I need to store it in an object, what type should it have?

so, does anyone know why some, but not all, SWING apps don't render when using compiz/beryl as window manager?

store it in an object?
Why not use a BufferedImage?

then my object will have bufferedimage

yay!

heh, amazing, isn't it

surprising, considering the advice
normally, given "use bufferedimage" people would say "so I'll use an org.w3c.Document!"
the response to that, past "you're an idiot" would be "so at least use CDATA" and the Document-user's response to THAT would be "no, I'll just use ints to represent each byte"
so a 2k image would end up taking 468k of XML, and ungodly amounts of RAM
ah, good times, good times.

how would i go about limiting access to a servlet of mine if the request didn't come from an applet that originally came from the same machine as the servlet is on?

but BufferedImage ctor requires width/height.. and i'm getting the image host from http i only know its length..

I'm just lucky I have so much faith in humanity.
so use Image instead.

aight

the request object has the remote user's IP

jottinger, is there a way to check where the applet came from though?
jottinger, is there a way to check where the applet came from though?
jottinger, im sorry man

the request object has the remote user's IP

jottinger, how does that inform me where the applet came from?

…

jottinger, this is an applet that gets downloaded to the client

jottinger, Image is abstract hmm.. i'm getting the image from an inputstream (from http)

jottinger, so the remote ip would be the person behind the browser right?

the applet, if it communicates with a servlet, does so via a request object… to the servlet
so the servlet host gets a request that has… wait for it… the remote user's IP

Content-Length 922040
Content-Disposition attachment; filename="SLP2007081213_001.jpg"
like this.

jottinger, ok i understand that, but how does the remote users id help in letting me know if the applet originally came from my server or not?

I really think I need to hop off of IRC for a few minutes… I told my son yesterday that I was stupidity-intolerant and I need to back that up with actions.

jottinger, hope he doesn't take that the wrong way haha

you do understand that you said you wanted to restrict access to the servlet to applets that had downloaded it, right?
If he's not smart enough to take it the right way, tough.
s/it/from the same server hosting as the servlet/

jottinger, percisely

so… the servlet knows what server it's on. The applet tells the servlet where IT was from; when the applet is downloaded, NOTE THE REMOTE USER'S IP. Then match the remote static ip hosting from the applet to that list.
I typed that really slowly so you might understand it.
if that's insulting, ask me if I care… I've told you at least three times already. Maybe more, but I can't be bothered to count.

does anyone here ever have used Sun's SyndFeed for RSS??

You mean, from Rome?

jottinger, assuming someone runs with something your saying is not telling them three times, i believe what you just said is the only thing that fits what i asked, and thank you for that

Rome != Sun's… even though Rome is run by Sun employees
I gave you the information you needed. Remember "the servlet gets the remote IP"?
That's the water. I led you - the horse - to it.

hibernate noob .. http://pastebin.com/d4f1f026c if anyone got the time, can you tell me why only the parents are getting persisted and not the children ?

are the children mapped, CyTG?

autogen' reversed with myeclipse .. so they should be yes

are you persisting them specifically?

dont know ? i just attach them to the paret Test2 and does a save on that .. shouldt that persist the whole structure including children ?

session.save(test3) in the for() block
no

no ??

no

oh my goodness
so you're telling me i have to persist the parent first, and then the children one by one ?

why? If you want it to walk the tree entirely, then you need to use an OODBMS
no, you can persist the children first and then the parent
unless the children rely on the parent existing

they do .. constrained in the database

Or you have the cascade rules set up.

read the docs. and use a transaction.

i am using a tx .. allrighty

(set up so that they do so)

why do your children have a ref to the parent?

i did read the docs .. found some comments with someone having a similar issue as me, wich is why i was pretty much aligned with the thought of persisting the parent would automaticly traverse the structure ..
jottinger ask myeclipse.hibernateperspective.reverseengineer .. they just do..

well, modify your mapping if you can, unless you really do tend to get the children and then look up the parent

http://forum.hibernate.org/viewtopic.php?t=956859 … this dude is apparently persisting children with a save on the parent ..

maybe his mapping is set up differently then.
I dunno… JPA tends to want you to save each mapped entity.

maybe .. allrighty .. ill look into the mapping .. id just rather not touch that since its autogenerated .. you know, next time theres a change in the database i either do it manually or reverse and apply "patches" ..
okay thx .. ill look into it..

With my limited knowledge of JPA it seems that saving our parent with hopes of it saving yoru children states as well would be problematic. And it would be best to save each node as you go.

is there a servlet or anything invoked when just a static html file is requested in a tomcat server?

no.

jottinger, may i ask then, how I could store a user ip without anything knowing about the applet being downloaded?

you can, however, set up a servlet filter, which WILL catch html references.

jottinger, ah ok, but isn't that a "servlet" filter?

you could also use JSP if you wanted to, instead of an .html file, but that'd be dumb.

jottinger, i agree

that would fall under the "or anything" category, assuming you set it up.

ok cool thanks

golly, school just started up again, didn't it

well my client isn't recieving some messages, so i was wondering if that was a possibilty, or if its a problem server-side

chances are it's the server-side problem.
That, or Java has a bug!

what kind of input?

I'm apparently not in a good non-sarcastic, non-cynical mood today.
I blame you

input coming in over a socket should be queued by the OS

Dunno who has been punishing me, but someone certainly has.. I've been fixing bugs in vb6 stuff the whole day

well, it would have been pretty easy to spot someone trying to impersonate you..

where is ricky?

yes, spot the crowd… people wouldn't have run away quite so fast
not here
and that's gooooood

jottinger, what about sending the results of getDocumentBase() ahead of the request the applet will be making to check that document base is served from the server? is there a hole with that?

very very very good

hahaha
the applet can only communicate with the hostname from which it's downloaded
that's the applet sandbox

~tell gaillard_ about applets

hahahaha

8^)=

jottinger, i know that, but i am only trying to make sure that someone can't access the servlet that is not from that applet

yes…
but you see, THAT'S WHERE YOUR SERVER CODE COMES IN.
in fact, if you want to be truly clever, use your filter to do that… by only invoking the servlet if the session has downloaded the applet.

code? what?

But ignore that, you're not ready.
if you try to do that, you'll ask me more stuff and I don't want you to.

jottinger, why are you hear then, people come here to ask questions
here*

I'm here to learn.

not teach?

no.

help i mean*

…

well i appreciate the help, but don't complain if your helping and you don't want to, you don't have to obviously

I mean, what the hell do I get out of teaching or helping

jottinger, all about "getting" are you?

lets talk about the knapsack problem or solving world hunger!

Teh Warm Fuzzees [tm]!!!

a warm fuzzy glow?
lol

yes. I want to get a programming culture around java host that's competent.

gaillard_, i have an interesting project to work on
could you help me?

That's what I want. That's what will satisfy me.

andresgr, i could try
jottinger, if you don't care what others want, i doubt they will care about your interest

competent java programmers? for shame

… unless what I want is to the advantage of those from whom I want it.

jottinger, i doubt this would be the case

… in which case, actively denying my desire would be disdvantageous for the ones doing the denying.

jottinger, this is no business its just a chat channel

But that's what happens all the time anyway.
I think you fundamentally misunderstand what I want.

this is a chat channel occupied by those who are in business

what a surprise.

jottinger, i could care less, considering you could care less about what i want, see how that works?

*couldn't* care less
saying you could care less is meaningless and illiterate

but, see, I do care what you want… I just don't care to guide you step by step

cheeser, very good english major, english is not my concern

because that wastes my time and teaches you nothing

step by step
day by day

jottinger, perhaps
tmccrary, hahaha

what could make me feel this way

i actually have a bachelor's and a master's in CS and yet I still can speak coherently.

I don't have a degree at all and yet I can master grammer.

But you're one in a million baby
grammAr

it would seem so.

you lose

oops! I did it again!

i have a simple questing with a simple answer i am sure, no leading required, how do i check that a request is coming from an applet and not something else?

have you ever met me?

cheeser, how about that, but its still not a requirement.

no, but I want to. Oh boy do I want to

I disagree with your "no leading required"

cheeser, just call microsoft right now and you'll see what i mean

I gave you a huge pointer earlier and… you missed it

it shows intelligence, though. sounding dumb is … stupid.

I gave you another pointer… and you missed it

i probably would just append something to the URL. some token of some sort.

every time I've pointed you in the right direction, you've consistently missed it

i mean. i would if I just gave the problem a little thought.

I'm all about the enablement.
yeah, imagine that. a LITTLE thought.

jottinger, i don't see how ip's can indicate request from withinside an applet or not

tee hee hee

Point, match, me.

~spoonfeeding

Spoon-feed a newbie for a day and he will come back with more questions. Teach him how to find his own answers and he'll leave you alone.

nice

That's okay. You're complaining about other programmers being clueless. Right now, I'm beating salespeople over the head

i challenge what you said, ip has nothing to do whether its an applet or not

hahaha
~be jottinger

I hate you.

Yeah, salespeople are the bane of people would actually have brains within their head

~be jottinger

Darn you all to heck!

jottinger, have some pateince for those who know less, it will go a long way
patience*

you think I haven't shown you patience? Boy, you don't know what hotheadedness is.

cheeser, better cheeser?

What is this deal with an ip dictating whatsit?

he's trying to restrict access based on server *and* client
very very hard, you see

tmccrary, i just want to check if a request in a servlet came from an applet or not

well done! *golf clap*

This is for a security purpose? Not a good start

s/.[^\?]//

tmccrary, would you explain why? I can't read what i am to infer by not a good start
if the applet is sandboxed, what else matters from the servlet end besides stuff thats not from the applet?

The servlet knows nothing about the applet
the applet is on the client side

http://pastebin.com/d6e578f4a and a few more in a JFrame that is supposed to fake a machine where you pay with coins (€ is the Euro sign, in case you wonder) - I want the pay(amount) method to display the frame until the user has "paid" and then
close the frame and return whether the user paid or not (the default close operation is to just set the boolean wait to false) - can anybody tell me how to make this work? I
guess it would only be a minor change…

fuck!

I would but there is no girl around

tmccrary, i understand this, all i want to make sure is that the request was from an applet, thats all

Just add a URL parameter to the request and check if it's there. Make sure your applet doesn't include this

go gay
save the gene pool for others!

nah

This isn't a security feature, but it would let you change output on the servlet depending on the request

what would i not include it in my request from the applet, thats what i want to go through
i think it should be reversed then

could be, I don't fully understand what you're trying to do
either way though, that should give you the idea

tmccrary, ok thanks

heh
and an hour later…

if you are bored can you take a look at my problem please?

how to write an outputstream to a file
damn i'm trying so hard

objectoutputstream
serialize the buggar

huh?

indeed

if you have an outputstream, you're already writing to something

hmm.

since you can't read from an outputstream, you can't write it to something else

i filled in the blanks hehe

you can wrap it

~tell b0r3d about io

b0r3d, io is http://java.sun.com/tutorial/essential/io

b0r3d you wanna write an object to disc right ?

I already copied inputstream to outputstream but need now to output it to a file

then split the output into a file as well as the original target
b0r3d, uh
why did you copy the inputstream to an outputstream

proxy ?

damnit son do your homework. read that link

surely

no, I think he's just completely clueless

i think hes doing a lil proxy ..
useful for rippin of a protocol of sorts

hi all

i'm getting an image through an inputstream… I want the user to provide an outputstream (file or somth) so I write the image to it

so get the outputstream, and then write the image to it in a loop

is this channel for discuscion of web-development in java?

if the user wants it to go to a file, they'll give you a fileoutputstream

okai.. i was wrong

zipito_, maybe
depends on your question

the outputstream can be a file right?

I have a question about life-time of the servlet

oh geez

~tell b0r3d about javadoc OutputStream

b0r3d, please see java.io.OutputStream: http://java.sun.com/javase/6/docs/api/java/io/OutputStream.html

look at the list of subclasses

alright
thanks man

after the user connected to servlet, would servlet hold in server memory the classes, used by servlet, between requests?

yes, classes loaded by a servlet will generally stay in memory until that servlet is undeployed

do you mean classes or instances?

dont confuse that with objects created inside the servlet's doGet

http://pastebin.com/d6e578f4a and a few more in a JFrame that is supposed to fake a machine where you pay with coins (€ is the Euro sign, in case you wonder) - I want the pay(amount) method to display the frame until the user has "paid" and then
close the frame and return whether the user paid or not (the default close operation is to just set the boolean wait to false) - can anybody tell me how to make this work? I
guess it would only be a minor change…

I mean instances

only if the servlet does something stupid to hold on to them
but you're smarter than that, right?

if you want to keep objects that you're user uses throughout his interaction with your webapp, store them in an HttpSession object

I want to make my servlet to hold the dbconnection with user supplied data

the servlet won't hold on to them, but they can be stored in a session

*your user

can to be liking for sure

g[r]eek: that's not very nice!

session objects can only store other objects
i don't know if that answers your question about "binary data". what do you mean exactly? primitives?

yes. you create objects inside one servlet. you put references to these object in the session. then you can retrieve these references later on from another servlet to access your objects

i tried google
can you tell me what this particular one does ?
or is there a SUN page that documents it?

google contains 10 billion pages, im pretty sure there is something out there that explains it
rather google has indexed about 10 billion pages

If Sun has a page that documents it, then I imagine google has indexed it
haha, right.

google ain't all that

They've cached a fair amount of pages, but I'm not sure they've cached /that/ many

you know google has only indexed about 1/10 of the net, according to some studies done at berkeley

wow
I'd hate to be that other 9/10

So can any of you tell me what http://java.sun.com/jsp/jstl/functions does ?

For this, it is

Where, in a most ironic move, they've done their absolute best to fake decent typing and functional programming in Java, thus preventing me using it in a language which has decent typing and functional programming.

I saw "." and flipped out

That's because she wakes him up by humming

She feelt flattered about it until I explained what that meant.

It's how you explicitly bind type parameters in a generic method.

haha

You don't normally need to use it.

"Oh, so I'm your angel of the morning, like in the song?" "You bet. You're my fallen angel of the morning. My little morning star." She beamed.
Then later that day I told her the other side of the story.

I don't know the other side of the story myself

i would have beamed too. what's the other side?

is this the g/f I know?

Morning Star == Lucifer.

hahaha

heyas

oh, bother

JOlga.

roflmao

"it's cause you're a demon in bed"

hey, is there a way to send all keybaord input in a window to one component?

Oh right, of course. I lost my mind in that long list of static methods

(like mirc does)

I don't blame you.

"How art thou fallen from heaven, O Lucifer, son of the morning! How art thou cut down to the ground, which didst weaken the nations!"
Why Lucifer? In Roman astronomy, Lucifer was the name given to the morning star (the star we now know by another Roman name, Venus). The morning star appears in the heavens just before dawn, heralding the rising sun.

i was busy typing that lol

note that isaiah preceded rome by many, many years

which is why some say lucifer was envious of god (the sun)

~pastebin

http://papernapkin.org/pastebin

Lucifer the morning star became a disobedient angel, cast out of heaven to rule eternally in hell.

well… ruling in hell is questionable

The whole write up blames King James' scribes for munging that one up.

he's only portrayed that way in one book, yob

heaven for climate, hell for company

nice.

whoa, I must have joined #jesus on accident

http://www.lds-mormon.com/lucifer.shtml

http://papernapkin.org/pastebin/view/1297

whew

they're still here

read my pastebin its two really good jokes

I actually joined #jesus
on accident, lol

Me too…

I don't think you can take the moron church as being authoritative on hebrew angelology

and then promptly left

Must be a sign

Knowing all this just makes the joke on JOlga funnier

anyone know satan's hebrew name without looking it up?

shai tan

g[r]eek: no

shazbot

Belzebub?

shai-tan postdates the concept
no

bush

It wasn't angelology, it was smybolism. For the transition we can blame the church.

I did at one point. Damned if I can remember it though.

i did once. nah belzebub is a demon

close, but bush was the angel of stupidity

shailoh?

g[r]eek: no

haha

Ottingerberg.

haha, no

I just went and looked it up
I am a cheater

yes, you are

and I don't mean the catholic church or the church of england, I mean institutionalized faith

samael was his hebrew name

On the day of atonement, a gift to Sammael [a Jewish name for Satan].

wondering why shai tan came to mind

mythology is fun
That's arabic

g[r]eek: islam
also, you've read frank herbert

in greek and latin its diablo
indeed i have

Although i find jewish/islamic/christian mythology the least colorful
and the least interesting

who, despite being jewish, wrote Dune with a muslim theology in the desert
well, they were monotheistic and largely faithful
but you should read the aggadah, it's pretty colorful

well i always figured he based the fremen on exiled jews

g[r]eek: no… fremen were exiled muslims

hi

i found my answer finally. whew

mind you, i was 12 when i read dune.
my grasp of religion was limited to greek orthodoxty
*orthodoxy

g[r]eek: he uses islamic imagery almost constantly in dune

t = Collections.emptyMap(); foo(t);" but this doesn't "foo(Collections.emptyMap())"?

perhaps i am missing something, but i am trying to have a passthrough filter for servlets but is there no way to exit the chain of filters?

yeah worms

g[r]eek: Judaism shows up in Dune but almost never really positively
Dune, Jews show up explicitly as Jews

how are the sarduakar jewish?

my favourite concept was that of the bene-gesserit

They're the ONLY ethnic group that survives unchanged, but they're also slightly … unadmirable
see the Dune appendix, he makes reference to the Sardaukar's use of Towruh

really

yes

yeah ok. and the fremen are actually the jews in dune dude

"sarduakar approaching" - music change - crap pants

you know, distinctively marked tribe, enslaved, forced to wander the desert, waiting to build their own kingdom and a messiah. it's pretty ironic you missed that.
you know, distinctively marked tribe, enslaved, forced to wander the desert, waiting to build their own kingdom and a messiah. it's pretty ironic you missed that.

never thought of that, cool

yeah i agree with meeper
that's the exact interpretation i had

off hand psuedo references to judeo, christian systems showup frequently in sci-fi. the matrix comes to mind.

apart from being off-topic, the fremen are as much islamic descendants as anything else.

the more I think of it, though, I think he refers to the torah's use on Salusa Secundus, not the sardaukar specifically

Hello.

even the word muadid is a hebrew word

cheeser:

mohadib

but anyway, try ##dune for all this

and the fremen used far, far, far too much islamic imagery and terms to be jewish in nature

is it possible to receive key-events while the frame is not focused, without using JNI?

how so? What does it mean?

I mean, really… ALIA?!

no

herbert's use of world religions is a lot more complicated then stealing words. trust me. the fremen are the jews and paul is moses.

so you mean the guy and his lady boy brother

yeah like dave rooney

haha

no.

great - can I spend my karma point on some help with swing?

?

tmccrary, one of the matrix directors had a sex change?

k, then i'll have to use JNI

I agree that his use of religion is far more complicated than mere words.

yes?
….

thx

But the Jews aren't identified with the fremen.

nevermind.

oh, pipe down.

Sorry, wrong channel. Try #dune-religion-and-everything-not-java

I was wondering why you opped up…but I see now.

~JNI

Overlook217, JNI is http://java.sun.com/developer/onlineTraining/Programming/JDCBook/jni.html

In March 2006, the San Francisco Chronicle reported in an article on transgender people that Larry Wachowski "has changed his sex and is now living as Lana Wachowski". [8]

…

I want one particular textField to receive all keystrokes - like mirc

My eyes skipped and I thought that was part of the JNI factoid for a moment

is there a non-horribly-involved way to do this?

cheeser is silencing anybody who talks about the matrix?

no. just non-java talk

oh
~batix

svm_invictvs, I have no idea what batix is.

svm_invictvs, batik is a set of Apache libraries for manipulating SVG documents.

do not talk about matrix club

t = Collections.emptyMap(); foo(t);" but this doesn't "foo(Collections.emptyMap())"? The latter complains "no such method foo(MapObject, Object)" when in fact foo is only defined for MapString, String

because in the latter case, it's too hard to imply the context

really?
it's too likely to run into ambigious matches?

try Collections.String, StringemptyMap();

?

heh, I must have missed something interesting

that worked
oops, yes, that worked
I didn't even know that syntax was valid Java thanks a lot

non-java talk

Alot of matrix talk. And meeper being a douchebag as usual.

weird!

yeah, it's hideous

Agreed. See above snippet.

jhg
my voice is back

is there a tool that will automatically write javadoc to your files?

(I really wish the inference of parameter types was better)

all i need is basic information…

uh…

I didn't know you could call generic methods like that

IDEs have some support for that

(But there are so many things I wish for Java )

an IDE will generate all the @param stuff for you

I had a Perl script that generated javadoc for simple get/set methods
it had some quirks but it was surprisingly coherent

yeah i need something like that, trying to figure out how to do it in eclipse without having to actually start the javadoc comment line myself.

For some reason, one of my JSP tags renders repeatidly until an out of memory exception is thrown…

Ecliipse can do that, too, I think.

I wonder how many people had to run to their IDEs to see if that syntax *really* works

What syntax?

the Collections.String, StringemptyMap(); thing

I thought that's how it was done…

Collections.Foo,BaremptyMap():/
I, for some reason, just thought that iddn't work….
Though that works in C++…

well the C++ thing is actually totally different
it just *looks* similar

Syntatically similar, implemented way differently.
heh, I have some dangerous downcasting in my code, teehee.

i'm having trouble printing out an arraylist using jstl - does this seem correct? http://pastebin.com/m724da686
the error i get seems to exist that the arraylist does not exist in the transfer object stored in a session - http://pastebin.com/m4aa08601
but if i print out the session variables it does exist

Doesn't exist as in it is null?
and where are you printing it out?

i have logging on in the form action bean that forwards to this jsp page - and i use a get method to print out the arraylist and it is there
i have also tried using java on the jsp page itself to print out the available objects stored in the session and it is there
i am also able to use jstl to print out simple strings stored in the session object - but not this arraylist
i use setter methods to set both the strings and this arraylist into the transfer object - i don't understand why jstl is not able to print this arraylist out like it is able to do w the strings

brb

this might interest you, regarding my Collections.emptyMap() question: http://forum.java.sun.com/thread.jspa?messageID=9825080
the guy brings up a good point

invalid console appender config detected, console stream is looping"

yeah, sounds like he pretty much nailed it
though you can't have more than one method of the same name that takes just a Map as a parameter

are both Map at runtime

i has a problem

bad english?

i've always had that one
sorry, i tend to say "i has a .. " silly internet meme

bad internet connection?

anyway, I have a problem
actually i do have a bad internet connection, it hates me too
but that's not todays problem
todays problem is maths (yes maths hates me too)
gosh, no love for me at all!
i have an object. im trying to give it a field of view. so that i can detect if any other object comes into its field of view (meaning a collision is iminent)
so field of view would mean it cant see directly behind itself, might have say 120degree field of view etc
wokring out the distance between itself and another object is easy, but working out if the object is within the field of view
i dont know how to do it in java
its a 2d environment, so cant use local co-ordinates to work it out.
if it was in 3d i could do it i think. but 2d… i dont know
i fail

eh? 2d is easier then 3d, i think.

2d is just like 3d, but everything is on the same plane
it's quite simple I think, basic trig

except with 2d, i cant say.. oh if its withing this distance and the y co-ord is positive, its in field of view

but an imminent collision would not be limited by field-of-view, would it?
forget about X and Y - draw a triangle with a 120 degree inside angle

well the field of view is for detecting where its neighbours are, and see it will try to avoid its neighbours based on how far away they are etc

so you have a large number of objects and you need to keep track of distances between them?

its a flocking simulation

iirc interval trees are good for that

each object tries to avoid the other, keep together and match each others speed
they all have the same individual behaviours, which contribute to a total group behaviour

but only the other objects it can see?
I see
sounds interesting

my focus is on different ways i can do the "dont bump into each other" behaviour

ok, so step one would be to figure out what other members a given member can "see"

exactly
id like to implement a field of view, so it will try to not collide with objects in its field of view

so each member has to have a "direction" that it is facing
any other object within the field of view, (and probably within a certain distance) would be considered "visible"

each one has their xy position, all the behaviour rules return new velocities, a new velocity is given to the object and enables it to update its position

you're missing a few things
1) each one has to have an x,y position *and* a heading

like direction/heading?

yes
2) you'll have to factor in reaction time, otherwise you'll probably have a "perfect" flock every time

yeah, what you're saying does make sense

how to return from an exception?

so i need to figure out how i do direction

i'm trying return;

you could probably do a generational system (like the game of life), and say it takes between 3 and 5 generations of consistent behavior by a member in order for that member to be "imitated"

empty catch, but don't do that

hmm

if a member is acting erratically, probably the other members would ignore or avoid it

r0bby, actually that doesn't work because my whole program is crashing.
it's in main.

you want to catch the exception and recover

well i'm catching it i want to return to main

direction is easy - your Member object would have: double x; double y; double heading; // in radians maybe

so how do work out its heading?
i mean i have its xy and its x velocity and y velocity

well x velocity and y velocity is easily convertable into r-theta
basic trig
and in fact I think r-theta will be easier
double x, y, heading, velocity;

i feel stupid, because i know what you're saying, but my trigonometry is shameful

r0bby?

trig is essential

aye, so im learning with this

if you get absolutely nothing else out of math - get trig - whether you're going to be a carpenter, schoolteacher, programmer, whatever
it's essential

imagine, i got through 4 years of computer science not knowing this kind of trig
:/

that's… insane

sohcahtoa!

you should have had this level of trig when you were about 14 years old
anyway, off to feed the children

well thanks dmlloyd

i only used trig on my degree for a laugh

il go have a think, and read up on my trig

something is throwing an exception inside main, would I still be able to recover from it?

sure

damn. that guy almost made it all 21 days
how so what?

not necessarily

Heh

oh. well, check this. this is kind of an advanced topic, but I think you can handle it.

aight

you can actually *catch* that exception in main() and handle it.

safari is neat… although I'm on the cheap plan and have to swap 10 books in and out

i'm doing so ..

no crashes that way

cheeser, I have a System.out.println("hi"); after the line that threw an exception in main.. it's not printing out.

well, duh.
it'll go to the catch block
you say you've read that exceptions link?

I want it to return and print that line

it won't if the method throws an exception
go read that page.

~coffee whaley

but i'm catching it in main

so print in the catch block

so no way to go back to the normal flow of the program?

structure your code properly.

that's what I mean by the whole program would crash.

meant*

wrap just that one line in a try/catch

hmm

that's not crashing. that's normal exception handling.

oh damn
sorry I'm blind

if it crashes, it's your fault.

s), and Class B extends A with method foo(Collection s) in what cases does it override?

but everybody was right, you could have googled and found my solution.

I know, I found on google

i believe so
PaulEU:

it was not a yes or no question

I think subclass methods always override super class declarations where the signatures match

see ya.

That will always override or generate a compiler error I think. I'm not sure where it will do the latter.

by

so in this case i believe B will override A's declaration

I think the question here is what happens if only the erased signatures match.

TIAS … you should be able to do that with a couple of println()s

Morally it shouldn't override, but I'm pretty sure methods overloads are resolved based on their type erased signature.

ok sorry, im not well versed in all the generic ins and outs yet =\

This is an obscure one. I've no idea what the answer is without TIASing myself.
I just know that it's either going to be an override or a compiler error.

s)

the runtime doesn't see the generic method signature. it only sees the type erased signature.

so Collection s is considered a type erased signature?

though it should be a compiler error in practices. subclasses aren't allowed to narrow their parent's interface

s is a generic method sig?

i was considering cleaning up the base class, adding proper typing, but wanted to make sure that it would not break things

hi guys, I am trying to run the azureus java client, but I am getting the error "could not find the main class. Program will exit". I know this is a common error, but despite reading all the internet pages on it, I cannot get it to work. The command I am running is java -cp .
azureus2.jar
can anyone help, please?

Yes, that's clearly correct though.

java -jar azureus.jar

doesn't exist at all at runtime. it's syntactic sugar for the compiler to help you spot errors in your code and make your code more readable.

That it is a compiler error I mean.

does exist at runtime. It's just not enforced.

one, use the scripts that come with azureus. 2. try an azureus forum. this isn't an application support forum.

it's not wise to narrow a base class' interface. you probably will break something and will have to change all subclasses.

In a client-server architecture where everything the passed over the network is serialized and there is a "common" jar (used by the client and the server) - would you convert all "common" data structures as soon as they come from the server to client-only ones?

see above

Zaph0d^: it's a good idea if it's not too much of a PITA

defined "too much"? (this is an 'enterprise' system)

Zaph0d^: the idea is to build a facade so the client is decoupled from changes in the network protocol and vice versa.

is it possible to pattern-match over several lines in java?

that already exists. However, the client is still affected by changes in the server

Zaph0d^: well too much means if it's too much work. but if you only have a single client under your control then don't worry about it

or do I need to remove the line ends?

What you mean by line ends? Newlines or multilines?

meeper I was afraid that's the answer I'd get. actually, I'm afraid that's the answer I'd get from my team leader.

JLearn, yeah sorry, new lines
JLearn, I have an ical File and need to extract only the VEVENTs

yes its possible.

Zaph0d^: don't worry. when the time comes and you need to rewrite the client because it's not sufficiently decoupled from the network you'll learn the right answer

hopefully I won't be there that long.

hmm I have strange problem.. I load image, but its not visible on JPanel :/

JLearn, I thought pattern-matching could get me the single events

jPanel.add(new JLabel(imgIcon)); jPanel.repaint();

jottinger, I have been using the azureus version that has been compiled for windows, but there is a new feature in the beta release that I would like to test, which is why I am attempting to get this one working

Zaph0d^: then it's not your problem at all. do whatever is easiest.

JLearn, but now I'm not sure how to get only the lines between the tags BEGIN:VEVENT and END:VEVENT

and it don't show image, but I can read these dimension of file

talk to the azuereus developers. you're doing them a favor by wasting your time beta testing for them and they'll be happy to help you

jottinger, what I don't understand is where it is getting the reference to apache (in the above erro). On another PC the error references the eclipse application

I must use method paint ?

meeper, but is this a problem with azureus or my lack of knowledge ?

it's you

the problem is with evil open source developers who waste billions of dollars each year with poor documentation!

ask on the azureus forums. they'll have dealt with this already.

but mostly it's you
