Hi,
when i run my game in eclipse, everything is fine.
But when i export it as a runnable jar, i am getting openAL exceptions, the background music doesnt play at all and soundeffects sound strange as well.
I use "java -jar -Djava.library.path=.libnatives connections.jar" to start the executable jar.
This is the exception i get when running the game:

What botheres me most is that i don't even know what the error is about exactly :(
I hope someone can help me with this problem
[EDIT AFTER SOLVED]:
see reply #7 and #8
please post this line here:
at gamestates.MenuState.setupAudio(MenuState.java:778)
here it is:
private void setupAudio() {
// grab a handle to the audio system
audio = AudioSystem.getSystem();
// set overall volume
audio.setMasterGain((float) gameSettings.getVolume() / 100); // getVolume returns [0 .. 100]
// setup our ear tracker to track the camera's position and orientation.
audio.getEar().trackOrientation(cam);
audio.getEar().trackPosition(cam);
// setup a music track and start playing it
AudioTrack music1 = getMusic(MenuState.class.getResource("/data/sound/1.wav"));
audio.getMusicQueue().setRepeatType(RepeatType.ALL);
audio.getMusicQueue().setCrossfadeinTime(2.5f);
audio.getMusicQueue().setCrossfadeoutTime(2.5f);
audio.getMusicQueue().addTrack(music1);
audio.getMusicQueue().play(); // <
Line 778
}
private AudioTrack getMusic(URL resource) {
// Create streaming, looping, non-relative music clip.
AudioTrack sound = AudioSystem.getSystem().createAudioTrack(resource, true);
sound.setType(TrackType.MUSIC);
sound.setRelative(false);
sound.setVolume(1.0f);
sound.setLooping(true);
return sound;
}
Probably a classpath is missing so getResource doesn't find the wav-file.
and where would i add that classpath?
aside from that, if i dont stream the musictrack, but load it as a whole, i get an OutOfMemory exception, which seems to indicate that it does find the music file
Than you have to increase the heap-size of the virtual machine.
Add this to the VM-arguments: "-Xmx256m" to increase the maximum heap-size to 256 MB.
Hi again
It works now 
I had to set the java heap space to 512mb though. The actual .wav file is only about 73mb in size.
Isnt there a way to reduce the memory amount needed? mp3 doesnt work, right?
I still wonder why streaming doesn't work :-o I've also tried it with another .wav file, which is only about 1.5mb in size, but i got the same openAL exception that i posted in the opening post.
Anyways, thanks a lot for your help XD
I recommend OGG for audio.
Use Audacity to convert them: http://audacity.sourceforge.net
It is also perfect when you want to tweak/edit your sounds.
Thanks for the tip!
after using .ogg, i could even stream the music and i got no more OpenAL exceptions 
and i dont have to expand the heap space anymore as well.
