    Applet org.jboss.console.navtree.AppletBrowser notinited on

    Mark Wiltshire Newbie

      The applet is simply coming up as notinited. (on Firefox 2.0.0.2)

      I have had a look around the forums, but cannot find anything that is helping.

      I have recently upgraded Java to 1.6.0-b105

      Can anyone shed some light for me...

      I am not seeing any console errors...

      Many thanks

      Mark

          You might want to open the Java console in Firefox. Sometimes errors, such as missing classes for the applet, show up only there. Once I find the jar containing the missing class I usually put that jar into my war next to the other jars used by the applet.

            Many thanks Peter J,

            Here is the output from the Java Console, looks like I need to downgrade the java version I am running.

            Can anyone tell me
            1) How do I specify which version JBoss runs on? can I just specify it in JAVA_HOME environment variable
            2) What java version is supported?

            Many thanks

            Mark

              This is telling you that the JVM embedded within your browser is older than the JVM used to compile the Java code. If I recall correctly, version 48.0 is for code compiled with a 1.4 JVM, therefore the JVM in your browser must be 1.3. If you are running Firefox in Windows, you can open the Java Control Panel applet and change which JVM you are using. The other possibility is to install a 1.4.2 JVM (or higher), that should fix up Firefox.
