rollback problem with some RequiresNew

Hi!
I have a problem or more a question concerning RequiresNew. As far as I read in the J2EE and EJB Spec and in this forum and the JBoss Doku there are no nested transactions in JBoss right?

Now I implemented a CMP Entity Bean and set the transaction attributes for all methods to "RequiresNew".

The sequence of method calls is like this:

Client (without transaction) calls
|
|
Method1 (with transaction attribute RequiresNew) calls
|
|
Method2 (with transaction attribute RequiresNew)
|
Method2 returns without error.
|
|
Method3 (with transaction attribute RequiresNew)
|
Method3 returns without error.
|
|
ERROR in Method1 causes Rollback

This rollback in Method1 causes to rollback all changes in Method1, Method2, Method3!


How is this possible?
If there are only flat transactions, I would assume all changes from Method2 and Method3 are already commited when the methods return, So a rollback in Method1 shouldn't rollback changes from Method2 and Method3! In my opition Method2 and 3 must be declared as "Required" to show the behaviour stated above or there must be nested transactions.


Can anyone explain to me what's going on there?
Thanks!

Sorry, my fault!

I called a local method using
this.increaseBalance() inside a CMP Entity Bean, so there was no possibility for the container to create a new Transaction for Method "increaseBalance()" in this case!

Hi !
I tried to use CMT on my EJB but did not get rollback when i have forced one method to error.

Client (without transaction) calls
|
|
Method1 (with transaction attribute RequiresNew)
|
|
Method2 (with transaction attribute Required)
|
Method2 returns with error.
|
|
Method3 (with transaction attribute Required
|
Method3 returns without error.

error in Method2 should cause a rollback of Method1, but it did not happend at all.

Please advise as how it is done. Is there anythinh i need to do with my code?


Thanks
