Java!!!!!!!!!!! !!!


« Posted 2005-03-23 03:57:48 »

Hello,

will trying to get my little game startable from my homepage, I received this error:

java.lang.NullPointerException
     at com.sun.media.sound.WaveFileReader.getAudioInputStream(Unknown Source)
     at javax.sound.sampled.AudioSystem.getAudioInputStream(Unknown Source)
     at com.dnsalias.java.gage.sound.WaveEngine.load(WaveEngine.java:56)
     at Game.<init>(Game.java:88)
     at Game.main(Game.java:56)
     ....
     
The corresponding code looks like this
     
1  
2  
3  
4  
5  
6  
7  
8  
9  
10  
11  
12

    createSmoke = new Timer(250,this);
   
    chopper   = getClass().getClassLoader().getResource("./sound/copter.wav");
    explosion = getClass().getClassLoader().getResource("./sound/boom.wav");
   
    try {
           nchopper   = WaveEngine.load(chopper);     <-----  LINE88
           nexplosion = WaveEngine.load(explosion);            
    } catch (LineUnavailableException e) {
    } catch (IOException e) {
    } catch (UnsupportedAudioFileException e) {}

   

     
I can't see any error. Getting the file with getResource(..) should be the right way (AFAIK).
The wav-file is placed at the right location within my jar.

What's wrong here?

It might be the "./" in the front, I'm not sure classpaths like them. Also, the preferred way of accessing resources now is:

1  
Thread.currentThread().getContextClassLoader().getResource("blah");


At least thats what I've been told Smiley
