BlendInspect

emzic · August 11, 2007, 9:12am

hello,

i have written a small tool that visualizes the behaviour of the opengl blendmodes.
since it is maybe useful for some of you guys, i packed it in a jar and made it webstartable

you can webstart it here: http://www.embege.com/blendinspect/

any feedback is welcome! (even if it is completely senseless, tell me )
i would especially be happy to know if it runs on a mac, since that is the only platform i couldnt test it. thanks!

Doesn’t seem to work right on Linux (Fedora 7, JDK 1.6.0_01), I just get this tiny window which I can’t resize. No errors in the console.

thank you very much for the information. do other jogl-webstart applications work for you?

lhkbob · August 12, 2007, 10:07pm

I didn’t work with my Mac Powerbook Pro, it had an java.lang.Exception in the Launcher class. I’m nor sure what’s wrong since I’m not a very big webstart guy, however I haven’t tweaked with any java or webstart settings, so there shouldn’t be anything that I’ve done to make my problem unique to my box. Anyway, best of luck.

thanks for the information. do other jogl-webstart application like the jogl-demos work for you?
thanks!

lhkbob · August 13, 2007, 2:34pm

Most of the jogl-demos work if I recall as well as the jME demos, so I know webstart is capable of working on my computer.

thanks! hmmm, that’s strange. does anyone know what could be wrong with this jnlp file?

This is the exact exception I get if it helps you any:
java.lang.Exception

Worked great on Windows XP SP2 with the latest Java (actually, a Java 7 development build).

emzic · August 19, 2007, 6:13pm

lhkbob, thanks very much for the information.
i will need to look into this further. maybe it is a java-version problem, since i have only tested it with java6.

meanwhile, i am happy about any other feedback.

flipperke · September 7, 2007, 1:09pm

I have the same problem (tiny window) when I open it the first time. When I try to open it a second time (while the tiny window is stil open, it works like it should.
Linux
JDK1.6.0

emzic · September 7, 2007, 2:32pm

thanks a lot for the information! with tiny window you mean the java-webstart splash screen?

flipperke · September 7, 2007, 6:51pm

No, just a smal (3 mm by 10mm approx).
To be more precise, it seems to start at normal size (just a split-second), an then it goes to mini.

emzic · September 7, 2007, 9:58pm

hm, interesting. though yet i have no idea what the problem could be.

quintesse · September 12, 2007, 8:48am

Show us the code and we might be able to help

emzic · September 12, 2007, 3:12pm

the problem is, that the exception occurs in code which is not mine. (see lhkbob’s post above)
it happens somewhere in the java-webstart launcher code.

so i could actually post the complete code, which is quite a number of java-files, but i dont think that would help.

kbr · September 12, 2007, 4:23pm

The exception lhkbob isn’t enough to make a diagnosis. There’s another tab in the window which pops up like “wrapped exception” or similar which should have the real root cause.

emzic · September 12, 2007, 5:51pm

ah thanks! i didnt realize that.

maybe someone (lhkbob? ) can post that exception too, so that we can further investigate the issue.

thanks a lot!

lhkbob · September 14, 2007, 1:16am

I peaked into it further (there was no wrapped exception tab, but I remembered to check the actual console) and it’s a java.lang.UnsupportedClassVersionError. So if I’m not mistaken, that’s probably because I have java 1.5. So, sorry for leading you on, and it works fine for windows machine.

emzic · September 14, 2007, 10:03am

ah, ok
i was building it with 1.6 so maybe that’s the problem.

edit: ok i am using ant for my deployment. does anyone know how to configure it to build it with 1.5 compliance. is that a compiler flag?

thanks!
