Hello all, I'm still having problems as I stated in my previous "Rollback problems"
threads and am sending this out again in hope of some answers. What's happening is
that I try to insert a value that is already in the database, I get a duplicate entry
excep, I try to rollback the database, then castor prints out the stack trace for a
nullpointerexception, it doesn't throw it so I can catch and handle it my self.
After that I can no longer get locks on any of the data and keep getting
readLockTimeOuts.
They NPE is with the DuplicatEntry :
