non-EJB (EAR file) communicating to web service (EAR file)

[crash.test.dummy]

I have 2 projects:
1. non-EJB (using struts, spring, hibernate, pojo) deployed as an
EAR file
2. web service deployed as an EAR file

Running these two projects under WSAD works fine. Now I need to deploy
them in WAS (on the same server). How do I make them communicate to
each other?

Thanks.
