Hi, I have the following problem. I made a jar-file from JBuilder 3. And am using the Sun Java Plugin 1.2.2 to view the applet inside in Netscape, IE5 and Opera. Because i need to write to the local hard-drive, and i don't want those warning banners to show up, i'm signing the applet, and distributing the certificate to a client and use policytool. Now, when the jar-file is not signed, it runs fine. (however crippled) When it IS signed, i get an error message in both Netscape and IE5. In Opera, it will sometimes run, but not always. The error message in the Plugin console: Opening http://MyIP/vision/docs/Trivia/Trivia.jar no proxy CacheHandler file name: C:\Program Files\Netscape\Users\me\cache\MU13GVMV.JAR Opening http://myIP/vision/docs/Trivia/Trivia/Trivia.class no proxy CacheHandler file name: C:\Program Files\Netscape\Users\me\cache\MVF5IG0E.CLA java.lang.ClassFormatError: Trivia/Trivia (Bad magic number) at java.lang.ClassLoader.defineClass0(Native Method) at java.lang.ClassLoader.defineClass(Unknown Source) at java.security.SecureClassLoader.defineClass(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) Does anyone know what's going on here. I have no idea what i'm looking at here. Again, it DOES work when the applet is NOT signed! Can anyone please help me?
