Transaction context propogation

I have an Entity Bean with two methods A() & B() with the following transaction attributes

A() - Required
B() - Required

Processing is as follows:

Client -> some logic -> A() -> B()

client is not associated with any transaction context & method A() internally calls method B().

What would happen to the transaction context of B()? Would it get the same transaction context that was started in A(), or would it create a new one.

The specs say that the container interposes every method invocation on the home or component interface and applies the transaction parameters accordingly. In the above case the call from A() to B() is not a remote one, but a local one.

Since the transaction attribute is set to 'Required' for method B() and A() is internally calling B() then method B() will run in the transaction context of method A().


cheers.

B will run in A's transaction context. I don't think it makes any difference whether the call is local or remote.
