rudidokuMemberHi,
I’m new to hibernate. I’ve been following a tutorial on the hibernate website. My problem is that an exception is thrown when i try to insert a new record. I have noticed that the exception is thrown on execution of the commit method of the transaction object. The INTERESTING thing that I have noted is tha the record is always saved to the database (MySQL) even when the exception is thrown. here is the stack trace :
! inside CREATE!!!
! about to save
about to commit
