How to Debug RMI server ?

[Laufrech]

Hello,
I'm curently working with Eclipse on Windows XP.
A "software genius" is creating an architecture based on RMI servers. Even if
all the services are to be on the same computer. Do not ask me why: I am a
victim, not the criminal ;-)
I'll have to develop several RMI servers then.
Ok.
The point is: how is it possible to debug RMI servers ?

My RMI clients and servers are on the same computer. It's easy for the client's
side, but about the server, I haven't got a clue !

If someone has an idea, methods, or anything, please do not hesitate !!!

Thanks in advance.

First of all, your server will have to be launched with the following
run-time parameters passed to Java VM:

-Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,server=y,address=8000,suspen
d=n

Here 8000 is the port number that the VM will listen on for debugging. You
can choose a different port.

Then, with the server running, click on "Debug" button in the Eclipse
toolbar, this displays the Debug dialog. Select "Remote Java Application"
and press the "New" button. Fill in the Project field, set host to
"localhost", and port to 8000 (or whatever you used in the "address"
parameter above). Click on the "Source" tab and set the source lookup path
to include the source code directories of your server (you will need it if
you put breakpoints in the code and want to walk through the code, executing
statements one by one, or check the state of the variables etc.)

Finally, press the "Debug" button at the bottom of the Debug dialog, and
Eclipse debugger will connect to the running Java VM. At this point, you are
in business.

If you run multiple servers on the same host, you will have to choose a
different port number for each server.
