Using XMLDecoder in applications

If you use XMLDecoder to load data files into your app be sure to pass the correct ClassLoader^? to XMLDecoders constructor. Using the default system ClassLoader^? will not work. Follow this sort of pattern

        ExceptionListener exceptionListener = new ExceptionListener() {
            public void exceptionThrown(Exception e) {
                logger.warning("Problem Reading Config File : "+e.getMessage());
            }            
        };
        
        InputStream is = getClass().getClassLoader().getResourceAsStream("org/jdesktop/lg3d/apps/myapp/myconfig.xml");
        XMLDecoder decoder = new XMLDecoder(is, null, exceptionListener, getClass().getClassLoader());

Resources

Load resources from your applications jar using the following pattern

getClass().getClassLoader().getResource("org/jdesktop/lg3d/apps/myapp/myconfig.xml");
