I do this all the time with JSW and YAJSW. I believe you have all the info you need. Repeating your bullet from below: Use a Remote Java Application Debug Configuration with the proper host and port specified You must have a Run/Debug definition in Eclipse where the port = 8000. Run netstat -a and look to see the target port is not already listening (in use). Uncomment the wrapper.conf lines you specify below. If on Windows shut the service off (Stop service) in the Windows service manager. Run you application at the console or command line (service.exe or whatever it is called). With the suspend=y it should just hang in the command shell window with a prompt waiting for Eclipse. Then back to Eclipse and run the Debug definition previously created. If successful the Thread Stack should appear on the left. BTW: given the current global security status I would not use my company email on this forum. HTH.
