Just found something of interest http://www.objectweb.org/jotm http://www.objectweb.org/jotm/current/jotm/doc/howto-tomcat-jotm.html
A opensource transactionmanager which you can use to solve your problem.

Maybe to simple :-) consider the following snippet
int x = 0; try { x=x+10; x=x+10; somethingMightThrowingAnException(x); x=x+10; } catch (Exception e) { }
if somethingMightThrowingAnException(x) is not throwing an exception x would be 30 in the end. but if somethingMightThrowingAnException(x) is throwing an exception the value of x=20. For the transaction it should be 0.
I think you need a transactionmanager to solve this problem.

Hi List,
I have 2 methods that i am calling in same sequence.
+ txnMethod1() + txnMethod2()
I wish either both of them get _executed_ or none of them.
Can i rollback the state to what was before method1's _execution_ if method2 fails?
Is it possible or i should start thinking simple?
Think simple: throw an exception.
