Hi, Just curious about the change. We have a production system for almost 3 years and we use JMS as our backbone. And recently have increased a load on our clustered servers. We were using jdbc3 persistence which was recommended when we upgraded the jboss veriosn to 4.0.2. But i just noticed on the Wiki that JDBC 3 persistence manager is not recommended any more. Is there a link or performace results to compare JDBC 2 & 3 persistence? And the reasons why its not recommended any more. Any other information will be helpful.
