[ https://issues.apache.org/jira/browse/CXF-180?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Bozhong Lin updated CXF-180:
----------------------------
Component/s: Transports
Fix Version/s: (was: 2.0-RC)
2.0
Affects Version/s: 2.0
> JMS Transport support for transaction
> -------------------------------------
>
> Key: CXF-180
> URL: https://issues.apache.org/jira/browse/CXF-180
> Project: CXF
> Issue Type: New Feature
> Components: Transports
> Affects Versions: 2.0
> Reporter: willem Jiang
> Fix For: 2.0
>
>
> Here are some points on the JMS Transport stuff:
> [ulhas]
> Currently JMS Session pool in Artix uses different Message Receiver
> acknowledgement mechanism than Celtix to provide Transaction support.
> (Celtix uses AUTO_ACKNOWLEDGEMENT) whereas Artix uses CLIENT_ACKNOWLEDGE
> for server side.
> [Willem]
> AUTO_ACKNOWLEDGMENT just make sure JMS broker client
> received the message, but not sure about the client had processed the message.
> If we want to support the Transaction in CXF, I think we need to change to
> CLIENT_ACKNOWLEDGE to make sure the message had been processed in
> message level.
> [ulhas]
> Second part of the transaction support is in current JMSServerTransport
> postDispatch code. This is the place where the server make sure that the
> message received can be processed and it is safe to send the
> Acknowledgement to JMS broker to remove the message from topic/queue and
> commit.
> [Willem]
> In current CXF JMS Transport implementation the transport just provide an channel
> to send and receive messages. All the message handling stuff need to play with the
> Stream. I think it is a good place in the OutputStream close method to send
> acknowledgment to JMS broker.
> So if we want to support local transaction in CXF JMS, we just need change the Session
> acknowledgment and the OutputStream close method.
