I'm creating a distributed application using EJB3 and I want to know how to do the communication between my ejb objects. I think it would be such a mess having explicit calls to my session beans inside others session beans.
I was searching for EJB3 design patterns but I haven't found anything really clear and updated yet.
The impression I formed was that the OP did not have distinct coarse grained/fine grained ejbs.
In such cases a call to the ejb layer results in a lot of criss cross calls between fine grained ejbs sometimes force creating coarse grained beans on the ejb layer without even knowing it. Which is why I suggested taking a step back and addressing the cause at the root - have a robust session facade ejbs fronting.
Of course if the problem is not what I have outlined above, then session facade is not the right option.
