===============================================================================
In above codes, the line of "globalIdTx.get(id)" has been used to get a Transaction,
NOT specified action "importing a transaction propagation context into this TM".
But I found another implementation of "importTransactionPropagationContext" in
TyrexTransactionPropagationContextManager.java. So I guess that the implementation in
TxManager.java does not work/be used at all.
Am I right?
Because my job focuses on WS-Transaction, I want to leverage the implemention of JTA
in jboss to achieve "Transaction Context Propagation". If you've some comments/hints,
you could send them to me any time. Your replies will be greatly appreciated.
