I am not using an application server, I was running my own java classes
from qsh.

Eclipse already had the remote debugging as did my iSeries.


from qsh:

java -interpret
  -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=y
  SomeClass

in eclipse:
I started the debugger, pointed it at the ip of my iSeries and the port
above and it hooked into the remotely running java app
