[JBoss-user] [Messaging, JMS JBossMQ] - Distributed transaction and Message Driven Bean
Hi, we have been playing around with Message Bean to investigate how a distributed transaction works in an asynchronous way. But we could not make that working. Basically we have the following example: 1) BankFacade - a stateless session Bean 2) OracleAccountMDB - a message driven bean which internally invokes a OracleAccountEntityBean 3) MySqlAccountMDB - similar to the above but invokes MySqlAccountEntityBean 4) OracleAccountEntityBean and MySqlAccountEntityBean manages a bank account table in oracle and mysql respectively In BankFacade session Bean, there is a method call transfer which transfer 100 Euro from account in MySql to that in Oracle. Both MDBs are configured to use Container Managed transactions. Test Case: 1) Configure BankFacade to use Bean Managed Transaction, 2) In transfer method, explicitly get a UserTransaction and start a new transaction, 3) Send messages to tell OracleAccountMDB to deposit money and MySqlAccountMDB to withdraw money; 4) Once it?s done, call Rollback to rollback the whole transaction OR (other scenario) let one of the Entity Beans throw an exception. The result is the transaction is Committed instead. Is there a way to propagate the transaction from the Session Bean BankFacade to the MessageDrivenBeans?

[JBoss-user] [Messaging, JMS JBossMQ] - Scalable JMS cluster solution?
Hi, in our project we have the requirement for a scalable asynchronous communication protocol. We started with evaluation of different JMS products (f.e. JBOSSMQ, SonicMQ, OpenJMS). We are happy with JBossMQ, we were able to send and receive about 4000 msgs per second (topic with 40 subscribers) on one node. The next task is to improve the performance further by using a clustered environment. Therefore we performed some tests with a JBoss 3.2.5 cluster and found out that JMS is deployed as a HASingleton. That means we will get a reliable JMS solution but not a scalable solution with our cluster. And now my questions: === Can this behavior be modified? If not are there plans to provide a scalable JMS cluster solution? In the JBoss 4 Roadmap I found the information that reliability has higher priority as scalability, but could you please give my an idea if and when we can expect a scalable JMS solution. Thanks a lot and Best regards Nicole View the original post : http://www.jboss.org/index.html?module=bbop=viewtopicp=3841093#3841093 Reply to the post : http://www.jboss.org/index.html?module=bbop=postingmode=replyp=3841093 --- This SF.Net email sponsored by Black Hat Briefings Training.
