Java 4k Resources Thread

The service does not sign the jar.

Does the non-proguard .pack.gz version work?

[Ranger]

@TheAnalogKid

Any idea what’s happening here?

AFAIK, you can’t test a pack200 file without a web server. I’ve been trying to get it to work in this thread http://www.java-gaming.org/index.php/topic,21641.0.html

EDIT: Got it working using pjt33’s server code.

[TheAnalogKid]

Very surprising! I’ll try on my website then.

Riven, I’ll try later the other outputs from your service. I’m a baby-sitter for now

@pjt33

For people who don’t have a properly configured web server with which to test. This is a bit paranoid, so it shouldn’t let your box get rooted.

Works great - thanks!

I tried the non-proguard version of my game but now I have a different error:

[TheAnalogKid]

Just to narrow the cause, I’m able to run my game in an applet in a normal jar on my local machine. I really think there’s something broken or missing with pack or other formats. Or the optimizations applied brake something. I’ll try the service by uploading my jar.

[TheAnalogKid]

The jar way doesn’t work neither.

[TheAnalogKid]

Hmm, it was successful with the first generate pack.gz from copy pasted code BUT only one time. I tried all the other produced pack.gz and they didn’t work. I tried again the first pack.gz and it no longer works! I also selected “keep class members” option. And after each try I always deleted the IE cache and java plug-in cache. I’m very confused now.

BTW, what does “compile and self destruct” do? That sounds scary!

[Riven]

My tool isn’t doing anything fancy. It does: javac, jar, (proguard, )pack200, {bjwflate|kzip|7z}

The only part that can corrupt it is proguard, which is why I made it optional.

That’s actually quite weird… there shouldn’t be a Content-Encoding: x-gzip header, as it will cause the browser to ungz it, which will probably screwup any attempt the plugin makes at loading the pack.gz file (it will try to ungz the ungz-ed stream)

What kind of webserver are you running? Ah… Apache/1.3.39.

@TheAnalogKid

It will install a cute trojan :persecutioncomplex: on the server :

[TheAnalogKid]

There’s something with the service:

OK

EXCEPTION: java.io.IOException

Thanks, was updating the JDK on the server from 6u15 to 6u18 and ‘forgot’ that I had the a path including 6u15 hardcoded in the shrinker (for javac, jar and pack200). Fixed now.

@TheAnalogKid

Check out the source of the webpage.

Now I’m having:

Relax 8) I’m fixing it as we speak!

[TheAnalogKid]

No problem, I’m just reporting issues.

RIVEN IT’S BROKEN IT’S BROKEN AAAAAAAUUUUGHHH!!!

[TheAnalogKid]

So, I’m not the only one to struggle??? For me, nothing works with the service. Only plain jar really worked so far.

[Riven]

Struggle? Oow!

I was way too busy doing: http://www.indiespot.net/trace

Excuse me for the interrupted service :-X

A few seconds ago my 4K entry got shrunk just fine. How about yours?

[TheAnalogKid]

My issue might have something to do with the web server hosting my site. I have no control on it. I don’t even know any detail about it.

[TheAnalogKid]

Riven, could you share your html to launch your applet please? I may be doing something wrong.

Thanks

[Riven]

Update: I added a link after every generated file. Clicking it will test your applet in the browser

The browser will either receive a .jar or .pack.gz depending on the “Accept-Encoding” header.

Tested with 6u18:
[x] it worked when the server sent a .jar
[x] it worked when the server sent a .pack.gz
[x] Please test it here
