Without know what the application does, it is impossible to say how to fix it. Who did you get the app from? Does the app vendor offer support? Do you have the source code for the app? Are you sure that it is a an applet that is having the problem? Do you know what the applet is doing or attempting to do? Have you opened the Java control panel within the browser - that usually can tell you if the Java code got an exception.
