Interoperability of EJB2/3 between JBoss EAP 4.3 and JBoss EAP 5.1.1

Hi All JBoss gurus,

I had one geric question. Is Interoperability of EJB2/3 between JBoss EAP 4.3 and JBoss EAP 5.1.1 will work?

Let's take my EJB2/3 application is running in JBoss EAP 5.1.1 and ejb client application is running in JBoss EAP 4.3. Is this setup will work?

When we tested with both EJB2 and EJB3 and the communication seems not working good.

Thanks and Regards

I would recommend to use both server with AS5.1.

There are some difficulties with:
- Transactions, you cant have Tx span both server/application
- Security, works only if the applications are not JAAS secured (or you might handle the credentials in your application which is a mess)
- classloader, because of different client libraries that you have to use

So I give up to get this working because I can't get all things working
