Re: JMS Transaction and Redelivery

[Guy Katz]

hi; in JMS there is no transaction propagation from sender to receiver so there will be 2 transactions involved when the scenario involves sending and receiving a message.. if you are sending a message under a transaction it (say from a session bean), the message will be delivered to the queue/topic only under that transaction. if you are reading a message (say asynchronously from from an MDB) the transaction will include the message read and the code under your onMessage().  -----Original Message----- From: Venkatesan Krishnamoorthy [mailto:[EMAIL PROTECTED] Sent: Monday, April 26, 2004 10:06 AM To: [EMAIL PROTECTED] Subject: JMS Transaction and Redelivery Guys:   My question is regarding transaction propagation in JMS based messaging. In the article on the web site http://www.javaworld.com/javaworld/jw-03-2002/jw-0315-jms-p1.html, the producer and the receiver use different transaction and acknowledge modes for the corresponding queue session.  The message producer uses a non-transacted queue session while the message consumer uses a transacted queue session. Does it mean that the transaction specified on the message producer side is for the delivery of message from the producer to the JMS provider and not for the delivery of the message from the producer to the consumer? Also, what does it mean to have different acknowledge modes specified for the corresponding queue session at the message producer and the message consumer?   Can someone clarify this issue for me?   Thanks and Regards, Venkat =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff EJB-INTEREST".
