Transaction context

Could someone answer the following question :
Is transaction context propagated through different stateless session beans method call hierarchy. I am referring to trans-attribute.

Suppose, method X of Stateless session bean A -> calls -> method Y of Stateless session bean B, and the trans-attribute of Stateless session A is Requires and trans-attribute of Stateless session B is supports. Will the transaction context propagate from A's method to B's method ?

Any other points one should know when working with transactions and stateless session beans ?

Thanks in advance for your help!

It doesn't matter whether the bean is session/entity/MDB, the transaction context from Required transaction attribute method to Supports transaction attribute method.

Supports - runs same as calling method transaction context.
I hope this helps

When the bean B's method Y transaction attribute is "supports", it means if the calling method (X of A) has transaction, Y will run in caller's transacation. If the caller doesn't have transaction, then Y will run in unspecified transaction context. So, it will depends on bean B's trasaction attribute. not A's.

Hope this helps.
