Example 36 with TransactionList

use of com.sun.messaging.jmq.jmsserver.data.TransactionList in project openmq by eclipse-ee4j.

the class TransactionHandler method doCommit.

/**
 * Commit a transaction. This method is invoked from two places: 1) From TransactionHandler.handle() when handling a
 * client COMMIT packet. This is the common case. 2) From the admin handler when an admin commit request has been issued
 * on a PREPARED XA transaction.
 *
 * @param id The TransactionUID to commit
 * @param xid The Xid of the transaction to commit. Required if transaction is an XA transaction. Must be null if it is
 * not an XA transaction.
 * @param xaFlags xaFlags passed on COMMIT operation. Used only if an XA transaction.
 * @param ts Current TransactionState of this transaction.
 * @param conlist List of transactions on this connection. Will be null if commit is trigger by an admin request.
 * @param sendReply True to have method send a Status.OK reply while processing transaction. This should be "true" for
 * client initiated commits, "false" for admin initiated commits.
 * @param con Connection client commit packet came in on or, for admin, the connection the admin request came in on.
 * @param msg Client commit packet. Should be "null" for admin initiated commits.
 *
 * @throws BrokerException on an error. The method will have logged a message to the broker log.
