Is it possible (and not to difficult) to use eclipse to debug distributed java application

I am asked to help a company to change the way development is done. One point is the way how testing and debugging is done.
They have a distributed Java application. At the moment testing and debugging is done by running all the parts of the distributed application on the development machine.
For several reasons this is undesirable. For starters you are not testing a distributed system.

I do not have much experience with debugging Java applications in Eclipse. Especially not with remote debugging. And when the application is distributed the debugging has to be done on several machines at the same time.

Is debugging a distributed application doable, or is it better to continue working like it is done now?
