I have a message driven bean created using Spring. Transaction attribute in ejb-jar.xml is 'NotSupported' now if any method in the bean throws RunTimeException then what wil happen? By default if transaction is there spring will rollback the transaction. In this case transaction is not present then how spring will be behave?
Spring will manage transactions only if you ask spring to... You will have to create transaction manager and write transaction advice on the method, then on a RuntimeExec the transaction will be rolled back.
