Re: [eclipselink-users] How to disable auto-commit in EclipseLink

[patric@xxxxxxxxxxx]

After tracing and looking through the source code I think that this  
issue is even more crucial:
EclipseLink will only enable auto-commit after a rollback() or  
commit() of a transaction:

Please have a look at DatabaseAccessor.java:

basicBeginTransaction() will disable auto-commit()
basicCommitTransaction() will enable auto-commit()
basicRollbackTransaction() will also enable auto-commit()

This means that the result in the database of some JPA operations may  
differ if a tranaction has been rollbacked or committed before.

Why has it been implemented that way?
Is it an intentional behaviour?
