Can I add custom Java probes within the RootCause GUI?
No. Most or all of it must be done from the command line. In a GUI you can click on “Custom” button in the setup options, but this would only bring up a help dialog with the instructions on how to set the XMJ and the corresponding Java code. You can cut and paste from this dialog to create your .xmj file in the workspace. After that, you would probably only use the workspace and intercept mechanism to deliver your probes to the application in an automated fashion. You could apply these probes directly to your application using the apjava command. RootCause just hides this from the user of the application.
