Debugging in Java

Enable remote debugging

On the command line:

-Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n

address the address to listen to. 8000 is a common value but can be changed at will.
suspend if the JVM should wait for a debugger to connect before starting execution.

You should now be able to connect to the instance using Eclipse.
