Remote Debug the Server Side ResultSetFilters and ResultCheckers

Somebody on the internal newsgroup asked how to use the Eclipse remote debug capability to debug custom ResultSetFilters and ResultCheckers – that are running on the SUP server itself.

Somebody internally beat me to the punch, but it is described in:

Like I said, this is basically using standard Eclipse remote debugging, after the Unwired Server has been restarted in JPDA (Java Platform Debugger Architecture) mode.  You can set breakpoints and party in the code (using the brain-damaged Java debugger, but better than System.out.println()….).

On the internal newsgroup, one of the server people posted this helping bit:

You should be able to debug your filter running within Workspace by adding the same debugging JVM flags (all one line):

-Xdebug -Xnoagent

to UnwiredWorkspace.bat.

I believe you might need to use a different instance of Eclipse to run the debugger. I’ve seen some pretty strange behavior using the Eclipse debugger to attach to itself.
