if java’s own demo doesn’t work… ( sound does not play )
how the hell are we meant to take this stuff seriously.
Unhappy camper
Guess it’s time to revert to some more basic sounds…
Have a go with LWJGL instead.

No it is time to fix this bug. What is wrong? Can you display the console? Do you have an exception? It does not work on my computer because I have forgotten to erase old GlueGen and JOGL JARs:

ok, the site demo still throws, as said above: (it has worked earlier this year though)

My own program was giving me an exception on initing AL, this is however working again.
Exception in thread “AWT-EventQueue-7” java.lang.NoClassDefFoundError: de/jarnbjo/vorbis/VorbisStream
So it seems being dependent on some other site to get the correct libraries is just a crap decision, if they change or
are down for whatever reason the applet wont work, AND it wont get caught with a try/catch!
With LWJGL seems like i can put the relevant libs in the server, and be 100% certain they will work, not relying on outside links.
Still all this is a farcry from the ease of Flash deployment, and I’m starting to understand why most game sites won’t accept Java applications…
If I cant pack my game into ONE file, then app management for a big game site becomes that much more of a hassle.
They have to have the right stuff in the html, and extra files for either the jnlp header.
The JNLP loading is dead ugly… I’m starting to seriously think about switching to Flash after this project sigh
Sound doesn’t appear to be the only problem with that JOGL Applet.
When I scroll the page using the mouse wheel (Firefox 3.0.1.4; Java 1.6.0_15, nvidia 8800gtx), the 3d portion of the Applet (GLCanvas?) draws outside the bounds of the Applet. (temporarily dirtying the the “The applet above is instantiated with the following code:” text immediately below the applet)
As for IE8… it doesn’t even launch. “Error : java.io.IOException: Cannot find certificates for JNLPAppletLauncher class” :persecutioncomplex:
yes, never use nightly builds in a production system
If your using an applet with LWJGL, you can package your whole project into two jars, one jar will contain your project+lwjgl and the other will contain the native dll files.
Plus it has a nice loading screen
an example of a LWJGL applet project can be found here (OpenGL + OpenAL used, do also notice the fullscreen support :))
kapta’s game is looking damn good - clean loader, tells you exactly whats going on, minimum of ‘blank screen’
you wouldn’t happen to have written a tutorial on how to make this system?
Or is this all part of the Slick package?
the loader is LWJGL’s AppletLoader (handles all the dirty stuff with deploying natives, has a fully customisable loading screen, its own caching mechanism and provides pack200 + lzma support).
The applet and full screen stuff is part of Slick2D but should be fairly easy to do with plain LWJGL if you are familiar with OpenGL.
You can download the LWJGL Applet package to see a simple example on how to use LWJGL with applets, the slick wiki has a few tutorials on how to create similar applets with slick (but should be relatively easy to apply to normal LWJGL applets depending on how familiar you are with LWJGL and slick).
You can probably also get real time support on the lwjgl’s irc channel at #LWJGL on freenode.
(Bah: got this under Chrome:):

It means you somehow got a corrupt download on one of the native jars.
The problem is fixed in svn and latest nightly builds of LWJGL’s AppletLoader, so should no longer happen in future versions of LWJGL as the AppletLoader has recently got a much more robust and reliable download system.
Just waiting for LWJGL 2.2, it should be out any day now.
edit: @princec just updated the version on that game, can you give it another try?
That’s better
Cas
I am trying to find some time to do it between other work and moving - not sure when “any day now” is 
hopefully I can find some time on tomorrow or the day after that … I need to finish some other work tonight and and friday we’re moving.
and moving == semi-offline until the 26th earliest 
Final note, i guess jnlp is not really the problem- i finally understood that the main thing annoying me is the blank white screen while loading libraries, no way to get a splash screen in there?
The failing OggVorbis was inside code, not jnlp’s fault:
Is it in any way possible to use the NOT nightly builds, now using:
import de.jarnbjo.ogg.CachedUrlStream;
import de.jarnbjo.ogg.EndOfOggStreamException;
import de.jarnbjo.ogg.LogicalOggStream;
import de.jarnbjo.vorbis.IdentificationHeader;
import de.jarnbjo.vorbis.VorbisStream;
And one more question: why doesn’t a generic try/catch fail here?
try {
System.out.println("init Sounds");
// REM crashing here when de/jarnbjo not available...
sm=new SoundManager();
} catch (Exception e) {
e.printStackTrace();
}
Do I need specifically the Unsatisfied Link Error or something?
Should i be taking the actual source he uses and putting that into my code?
This is the closest i could find i think
http://svn.shredzone.org/tags/ifish/v1.4/src/de/jarnbjo/
I’d really like to be certain I have a working version as backup before I start
the overhaul to LWJGL…
Exception != Error - try catching Throwable insteasd (that should catch everything)
I dont quite get how. I can’t implement Throwable for SoundManager class:
“The type Throwable cannot be a superinterface of SoundManager; a superinterface must be an interface”
Could you explain in more detail how this should be done?
EDIT: Thanks Matzon!
try {
System.out.println("init Sounds");
// REM crashing here when de/jarnbjo not available...
sm=new SoundManager();
} catch (Throwable t) {
t.printStackTrace();
}
