org.apache.ojb.otm.core.Transaction.commit()
Commit this transaction. A commit notifies all listeners of this transaction. It then initiates a two phase commit on connections. Since, connections cannot be associated to more than one transaction at any given point in time, there is no neccessity to identify transaction.
