Transaction problem

[lhfdr]

Hi all,   I have two question about transaction!   1  When transaction begin, should enlistResource. When transaction finished, should      delistResource. But in program, call delistResource beofre commit. I think this      should called after commit(I know JTA specifaction say should delistResource before commit).      I want to know why call delistResource before commit, not after! Because I think      after commit, Transaction finished.   2  If local transaction, Transaction commit can current. But if distributed transaction,      Transaction commit is synchronized. Could tell me why?   Any help would be greatly appreciated. Thank you very much. regards, launce
