A powerful library which helps developers to implement audit functionality through Hibernate. It uses a global revision number and for every transaction commit it increases the global revision number by one and created an entity record in the designated audit table. The default table would be end with the _AUD suffix. And all you need is to add @Audited annotation to the entities and add the event listeners within the hibernate session factory bean. Pretty cool!

We had this new error from Hiberante – “java.lang.IncompatibleClassChangeError: class org.hibernate.cfg.ExtendedMappings has interface org.hibernate.cfg.Mappings as super class” – This is due to using the older hibernate entity manager/annotations libraries that were around when we upgraded to the newer 3.5.x version of hibernate. Hibernate includes the entity manager and annotations as part of the hibernate core library.

We use Ehcache extensively with Hibernate and for temporary caches. I had to write a JMS based distributed cache listener to update cache on a cluster and that works fine. And the JMS based distributed cache is also transactional.

Try the new Ehcache which is part of the open source Terracota kit at http://www.terracotta.org/dl/oss-download-destination?name=terracotta-3.2.1-installer.jar&bucket=TCreleases&file=terracotta-3.2.1-installer.jar

Red Hat recently released their updated SQA platform with JBoss Enterprise SOA Platform 5.0. MOre information here – http://www.theserverside.com/news/thread.tss?thread_id=59785

I’ve used other ESB’s including Mule, ServiceMix, Sonic etc. I think its a lot easier to integrate with these tools when compared to the JBoss Enterprise SOA Platform.

You would need this if you want to test your Web GUI for concurrent users. Easy to setup and install.
