I am new to using a Tomcat server and new to applets also. I am having the following problem and I was hoping that someone could help.
I have an html page in my web application that contains an applet. The applet classes are being obtained from a jar file as specified in the applet tag with "archive=". When I start the Tomcat server and access the html page from internet explorer on the SAME machine where the Tomcat is running, the page and applet display fine. When I go to another computer on the network and try to access the same html page in internet explorer, the page appears ok, but the applet portion is not there. There is just a blank area where the applet should be. The status bar says that the applet did not init. All of my other jsp pages and html pages are appearing fine on both computers. It is just the applet that does not work on the other computer.
I appreciate any help that anyone can give me. Do I need to physically copy the applet classes to some location on the other computer? Or how can I fix this?
Yes. It works on one machine but not on the other machine.
I had never looked at the Java Console before and I did not know how to do that. After reading your message and doing some research, I was able to determined how I could see the Java Console when the applet runs. There is a message appearing about the wrong version of Java on that machine. The working machine has Java 1.6 (I believe) and the non-working machine has 1.4.2. I am guessing that I need to update the version of Java on that machine. Does that seem like it could be the problem?

Yes, that could very well be the problem. The applet has apparently been compiled with a version newer than 1.4 (i.e., at least 1.5 or even 1.6). Either upgrading the Java installation to 1.6, or recompiling the applet with 1.4 (assuming that it doesn't use features introduced in 1.5 or 1.6) should do the trick.
