applet not always working

OpenGL Development JOGL Development
#1

hello, i try to run a jogl applet on a website and use the jnlp appletlauncher

the problem is, that the exception only occurs occasionally, not always. so sometimes it works, sometimes it doesn’t.
it seems to occur less often in firefox, more often in internet explorer and so far it never worked in opera.

this is from the console log:

if you would like to see the code, please tell me.

thanks for any help!

Could you please try the new Java Plug-In from http://jdk6.dev.java.net/6u10ea.html and tell us whether you continue to see the same problems?

#3

thanks, but unfortunately this also does not work with the new plugin. here is the error from the console:

this OS is vista64 but the jre is 32bit. may that be the problem?

#4

I don’t see any exception related to the actual OpenGL code running, only an InterruptedException indicating that the Animator’s thread was interrupted by the outside world. This is expected behavior during applet teardown. Do you have an example on the web we can look at? Do the simple JOGL demos work?

#5

yes, the jogl gears applet-demo works fine.

yes, there is an example online here:

http://www.embege.com/shadowmapping/applet.php

applet code:

package com.embege.shadowmapping;

import java.applet.Applet;
import java.awt.Color;

import javax.media.opengl.GLCanvas;


public class SMApplet extends Applet  {

	private static final long serialVersionUID = 1L;

	@Override
	public void init() {

		setBackground(Color.WHITE);

		GLCanvas canvas = new ShadowMapping("data");
		add(canvas);

		setVisible(true);

		setSize(getWidth(), getHeight());
		canvas.setSize(getSize());
	}

}
