I have loaded the latest beta, and then tried running my Applet when subsequently dies. I think I know what's going on here.... I am using the Java2 1.3 enhancement in my manifest that says my code requires an extension, in this case Java3D. Well, I am asking for at least 1.2.1, but then Java compares that to what is installed, namely "1.2.1 Beta2". Hm, "1 Beta2" is not a number that can be compared. The "1.2.1 Beta2" is not a valid version name. What can I do?? java.lang.NumberFormatException: 1 Beta2 at java.lang.Integer.parseInt(Unknown Source) at java.lang.Integer.parseInt(Unknown Source) at sun.misc.ExtensionInfo.compareExtensionVersion(Unknown Source) at sun.misc.ExtensionInfo.isCompatibleWith(Unknown Source) at sun.misc.ExtensionDependency.checkExtensionAgainst(Unknown Source) at sun.misc.ExtensionDependency.checkExtensionAgainstInstalled(Unknown Source) at sun.misc.ExtensionDependency.checkExtension(Unknown Source) at sun.misc.ExtensionDependency.checkExtensions(Unknown Source) at sun.misc.ExtensionDependency.checkExtensionsDependencies(Unknown Source) at sun.misc.URLClassPath$JarLoader.parseExtensionsDependencies(Unknown Source) at sun.misc.URLClassPath$JarLoader.getClassPath(Unknown Source) at sun.misc.URLClassPath.getLoader(Unknown Source) at sun.misc.URLClassPath.getResource(Unknown Source) at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at sun.applet.AppletClassLoader.findClass(Unknown Source) at sun.plugin.security.PluginClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.applet.AppletClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.applet.AppletClassLoader.loadCode(Unknown Source) at sun.applet.AppletPanel.createApplet(Unknown Source) at sun.plugin.AppletViewer.createApplet(Unknown Source) at sun.applet.AppletPanel.runLoader(Unknown Source) at sun.applet.AppletPanel.run(Unknown Source) at java.lang.Thread.run(Unknown Source) J.
