I have a large application that uses EJB 2.x entity beans (BMP). This is well-known to be a horrible persistence strategy (I can elaborate if necessary). I'd like to start migrating this application to use a much more expressive, transparent, and non-invasive persistence strategy, and given my company's previous experience with it, Hibe...
I have a J2EE 1.3 app that uses EJB 2.1 session and entity beans. Currently this app runs as an EAR file on JBoss. I'd like to switch to the SpringSource dm Application Server because of all the benefits that OSGi provides. Does anyone know if there's an OSGi bundle that can act as an EJB container? Can OpenEJB do this? ...
We use EJB2.x entity beans with BMP (bean managed persistence). It appears BMP is not supported in EJB3. We had wanted to stay current and upgrade to EJB3. Does anyone know if there are in fact any BMP options available in 3.0? From what I can tell, using 3.0, all entity beans have to use JPA and by definition ORM. There are some op...
The EJB3 spec indicates that EJB2 and EJB3 can co-exist in a single application. I wish to migrate my EJB2 stateless session beans to EJB3 stateless session beans. This question does not relate to JPA at all (that is a separate piece of work to be carried out in the future) I'm running on websphere 6.1 with the EJB3 feature pack instal...

I am not able to create EJB 2.1 beans using a wizard in the latest version of Eclipse. I only see options to create EJB 3.0 beans. I selected 2.1 as the 'EJB Module Version' while creating the "EJB Project". But now when I want to create a session bean, I don't see any option to create a 2.1 bean. Is there a plugin/setting I need to en...

Hi I can't find this in the JBoss documentation anywhere, so am asking here. Can multiple, non-clustered JBoss instances access and share the same TIMERS table (as used by EJB2 Timers Service) without upsetting each other, or does each one need its own table? In the case of a cluster, is it essential that the nodes in the cluster all ...
