I have solved the problem for our needs.
Now Activiti uses the HibernateTransactionManager and with
Now Activiti uses the HibernateTransactionManager and with
that we can make a full rollback!
Its not important that Activiti uses MyBatis,
because after a small research about MyBatis I found out that
MyBatis support the HibernateTransactionManager.

Methods for start and commit a transation
(all Transactions done after startTransaction are commit after call commit Transaction):
Code:
protected TransactionStatus startTransaction() {
PlatformTransactionManager manager = getTransactionManager();
DefaultTransactionDefinition d = new DefaultTransactionDefinition();
d.setPropagationBehavior(DefaultTransactionDefinition.PROPAGATION_REQUIRES_NEW);
transaction = manager.getTransaction(d);
return transaction;

manager.rollback(transaction);

private PlatformTransactionManager getTransactionManager() {

I hope this helps anyone who have a problem
to integrate activiti in a hibernate environment.
P.S.: I think it would be great if this method (or something like that)
P.S.: I think it would be great if this method (or something like that)
is also found in the activiti doucumentation,
because lots of projects currently using hibernate for persitences and in the activit
documentation doesn't exist a guide to integrate activiti in an hibernate environment.
