Hi all, I still got the problem that some of my sounds don't realy work like I want them to. Now I want to catch the exceptions the soundfiles throw but my problem is that the exceptions are thrown while the sound are playing, not if I start or stop them. I already catch the exceptions thrown by starting and stoping the sounds, but is there a way to catch these other exceptions?

The exception is: Exception in thread "SoundStream:file:/D:/..." java.lang.IllegalArgumentException: Could not open sound file: file:/D:/..." Caused by: java.io.IOException: javazoom.jl.decoder.BitstreamException: Bitstream errorcode 102 I think there was an error in the stream to open the file but only sometimes this hapens. And while playing the sound.

What kind of file are you trying to open?

It's an mp3 file. Most times it opens the file but sometimes not. I don't realy understand why.

I also had a problem like that (in my case, it threw an exception sometimes when the music was playing). I don't know why, maybe it's because of the file, maybe it's a bug in GreenfootSound, maybe something else.

yea thats clear. I know how to catch exceptions but only if I have code. The exception is thrown while running the soundfile and I don't know how to catch this.

Does the program still continue after the printed out exception?

yes it doe's but however the exception realy sucks. (I haven't used e.printStackTrace if you thought is was that)

Then you've got the exact same problem as I have. The exception is caught somewhere, but there's printStackTrace called somewhere. There's nothing I really can do for you, maybe somebody of the greenfoot team does.

So you think greenfoot catches the exception and prints the stacks content on the terminal? Yes that would realy make sence. I don't understand why Greenfoot doe's that but it would be an answer. Thank you SPower.

That exception is coming out of the Javazoom / JLayer library, which is included with Greenfoot for MP3 support. It may be buggy.
