[jboss-user] [EJB 3.0] - @Service POJOs information

I'm experimenting with the @Service POJOs on a new project, and I really like the concept, but I have a few questions about what I've discovered. I've confirmed that the single instance created allows multiple active simultaneous threads. Therefore if I have any fields, I need to synchronize them. 1) Is it therefore safe to use the synchronized keyword in my @Service POJO methods (in violation of the EJB spec)? 2) If I build a JBoss cluster, is there still just a single instance regardless of the number of machines in the cluster? 3) Do @Service POJOs have the same transaction semantics as stateful session beans? (e.g. can I use an extended persistence context in the same way?) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4056621#...
