I want to understand how does the communication happen between two SBB's in the perpective of SLEE.

My understanding is that :
When i attach one SBB entity from another SBB entity , the SBB entity is attached to the ActivityContext and the event is delivered to it.Is this correct?

Also,
1. What is the internal mechanism in SLEE for the communication between to SBB's i mean something like java invocation or webservice invocation etc.
2. What is the internal mechanism in SLEE for the communication between to services deployed in SLEE)

Please could some one throw light on this.

Thanks & Regards
Krishnaveni

Yes. In case of root and child sbbs, Otherwise SLEE uses its internal mechanisms to determine SBBEntities

Events + plus null actvities is the first thing that comes to my mind.
