[gl4java-usergroup] X11HandleAccess

[Dale B. <dr...@cs...>]

Hi,

I've been trying for a while to use the X11HandleAccess class to retrieve
the window handle, but haven't been able to get it to work.  The error I'm
receiving is:

java.lang.NoClassDefFoundError: sun/awt/DrawingSurface
        at
gl4java.jau.awt.motif.X11HandleAccess.achieveData(X11HandleAccess.java:40)
        at
gl4java.jau.awt.motif.X11HandleAccess.getWinHandle(X11HandleAccess.java:73)
        at TJRemote.TJRemote$MainCanvas.update(TJRemote.java:65)
        at sun.awt.RepaintArea.paint(RepaintArea.java:169)
[...]

I'm new to OpenGL in Java, so there may be something I'm just doing wrong,
but here's the code, it's pretty straightforward:

class TJRemote {

    static Frame f;

    public static void main(String[] args) {

        f = new Frame( "TJRemote" );
	f.add("Center", new MainCanvas(500, 500));
	f.setLocation(500,30);
	f.setLayout(new BorderLayout());
	f.setSize( 500, 500 );
	f.show();

    }

    static class MainCanvas extends GLCanvas {

	public MainCanvas(int w, int h) {
	    super(w,h);
	}

	public void update(Graphics g) {

	    GLContext glc = getGLContext();
	    if (glc == null) {
		System.out.println("Null Context");
		return;
	    }

	    X11HandleAccess x11 = new X11HandleAccess();
	    long drawable = x11.getWinHandle( (this), g);
	    System.out.println("drawable: " + drawable);
	}
    }
}

I'm using Sun's Java version 1.4.2 on Redhat 9.  Any help would be greatly
appreciated.  Thanks.
