No. Refer to section 17.6.1 of EJB2.0 specs - it clearly indicates that when a client (SB1 in your case) invokes a business method on a bean with bean managed transaction, the container suspends any transaction that may be associated with the client request prior to invoking the bean method. > * If not, then do I have to call userTransaction.begin() and userTransaction.commit() in SB2's business method? Yes. > If so, then this seems to negate what is said in the EJB2.0 spec sec 17.1.2(about nested transactions). No - this is not a case of nested transactions. Nested transactions occur when you can start (i.e. nest) a transaction within an existing transaction. In the scenario described above, you are always dealing with flat transactions (as mandated by the current EJB specs) - the container suspends an existing transaction prior to invoking the method in SB2. -Saurabh =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff EJB-INTEREST".
