Easy way to test action templates

Recently we’ve started developing our own (programmatic) action templates (in java) and design/change-time policies.
Is there an easier way to test these action templates besides the way we are doing it now: for the moment we write the executor source code in eclipse; we build the project; add the jar to the zip file and then we upload this zip to the action template inside the registry.

Can we not test these action templates directly from within eclipse ?
