    AppletBrowser does not appear

    tcn Newbie


      I downloaded JBoss, unpacked it, ran run.sh (linux, jdk 1.4.2-beta) and opened but the AppletBrowser on applet.jsp just does not appear (gray rectangle) . On Opera the page seems to have been completely loaded while Konqueror stucks at 99% and keeps on spinning the little wheels in the upper right.

      Well, I assume some exception has been thrown but I don't know which :-) And esp. I don't know why...

          Ok, forget about Konqueror :-) But I do have no problems with Opera and other applets.

              You need the Java Web Start Plugin for your Browser. The best way to do this, is to install the Sun JRE.

                The problem actually was (well, still is - too lazy ;) java.policy.

                  I had the same problem. I copied the jcert.jar,
                  jnet.jar and jsse.jar files to my jre/lib/ext dir.

                  Miracle !!! it works.

                  Well the exception in my case was HttpsURLConnection not found.

                  Hope this solves your prob as well.

                    If I put those 3 jars in jre/lib/ext, JBoss 3.2.1 won't even start - I get all kinds of exceptions. This is on JDK 1.4.2, on Windows XP Pro. I also tried changing jre/lib/security/java.policy to all permissions - that also does not work. I have a different system running 3.2.1 on JDK 1.3.1 on Windows 2000 Pro - doesn't work there either. One thing these two systems have in common is that I've moved all the services off their standard ports. The server download port is now 8283.

                      Ok. I have also been through these things, and it did not work. What some have said about jdk1.4 is correct, but it is ofcourse in the web browser this is important. Go to Tools - Internet Options - Advanced - and set the "Use Java 2 v1.4.1 for applet" on. If this option is not there, you must install J2SDK1.4.1.

                      I hope this helps.

                      Thank you for all the help forums have given me!
