We are currently using Jboss 4 and we would like to migrate to Jboss 5. I have following questions:
1. Are there any issues that we need to be aware of during migration?
2. We use Mbean to stop Session and Message Beans. Message Beans are stopped using Delivery Active.
3. We use clustering and have Singleton Services
4. We use Caching
5. We use clustered beans
6. We use hibernate API
7. We use Jgroups
7. Jboss remoting
We probably use more services provided by Jboss but I was wondering what impact it would have, what kind of changes we need to make etc.
I can only comment on 2: the JMS implementation was changed, and thus configuration of MDBs (declaration of queues) has changed.
