Hi All,
I think you may know this but I like to share with you all..

In spring normaly we use this code for transaction manager:-

DefaultTransactionDefinition td = new DefaultTransactionDefinition();
td.setPropagationBehavior(3); //transaction level
TransactionStatus ts = transactionManager.getTransaction(td);

If we create transaction inside transaction, it will run into deadlock situation.
The locks to tables not get released.
