Is there a way to debug plugin? Thanks.

Your mileage may vary but here's what I've done to get debugging up and running.
Use at your own risk, no guarantees...the usual stuff. :-)
In searchctl.bat, there's a command line to start javaw. (Shouldn't be hard to find.)
I added the following command line parameters:
-Xdebug -Xrunjdwp:transport=dt_socket,address=4000,server=y,suspend=n
I put those command line parameters between "javaw.exe" and "-Xrs". If you put 'em in the wrong spot, you'll have troubles.
That means my command line in searchctl.bat starts out looking like this after my modification:
%OH%\jdk\bin\javaw.exe -Xdebug -Xrunjdwp:transport=dt_socket,address=4000,server=y,suspend=n -Xrs...<stuff omitted>
Restart SES. Your plugins can now be remotely debugged.
In JDev, I created a new debug run configuration. Edit the new run configuration and click the checkbox that says "Remote Debugging and Profiling".
Still in the same window, you'll see a tree on the left hand side. Click the node that says "Remote". It should be the bottom option.
On the right hand side of the dialog, your display will change.
On the Protocol pull-down, select Attach to JPDA.
In the host text box, enter your host name. You don't need a bunch of path or port information...just the server name. For me, since I've got a test environment on my machine, I enter localhost.
Leave 4000 in the port
Specify whatever timeout you like. (I left mine at 2).
Click OK.
Start your debug session using the newly created debug run configuration.
By doing this, I've been able to successfully debug Authorization Managers, Query Filters, etc.
Some things to probably keep in mind if you get debugging up and running...
1) You may want to mess around with the number of threads and timeout options on the SES admin screens.
2) You may have to restart SES if you make a change and redeploy your jar file.
3) Bad things have happened to me if I restarted SES before I actually logged out. :-) Make sure and logout of the search and admin pages before restarting SES.
Hope this helps.
