This functionality is supported only if you are using the Classic Agent.
If Silk Test Classic sees the main window of your Java application or applet as MainWin instead of JavaMainWin, or recognizes the main window, but none of its child controls, you can run a Java status utility to help you or Technical Support diagnose the problem.
One common cause is that Silk Test Classic is not properly configured to test Java.
