Hai All,
I have to allow a user to make a lock over a record. So if I could lock over an EJB object, it will be possible, I think. That is, unless the user releases the lock, other users must not be able to do any manipulations to the record except reading. Can anybody help, how to do that ?
Thanks
Poorna
