Shelly, >From what I have read, Nested TXs run independent of each other with a Main TX. Rollback of one will have no impact on the other. Reference : ED roman Mastering EJB.
My question is related to Requires and RequiresNew TX. When meth1, Bean A has Requires TX attribute and meth2, Bean B has RequiresNew TX attribute Then the TX for meth1 in Bean A is suspended and New TX is started for meth2 in Bean B. If these 2 transactions are different then how is this situation different from Nested TX? ----- Original Message ----- From: "Aggrawal, Shelly (Cognizant)" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Tuesday, October 30, 2001 3:28 PM Subject: Re: Nested Transaction & Requires Attribute > Hi, > > Considering the same scenario that is: A method meth1 in Bean A is executing > with Required Tx attribute.
