ejb3 interop between different versions

A user is trying to call ejb3 beans from AS 5.1 -> AS 4.2.3
http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4263032#4263032 I believe we do not cover this scenario in our compatibility matrix tests? All we test is ejb2 access. Shouldn't we provide "some" ejb3 compatibility guarantees (& testing) going forward? /Dimitris _______________________________________________ jboss-development mailing list jboss-development@... https://lists.jboss.org/mailman/listinfo/jboss-development |

Calling EJB3 beans over major releases doesn't work.
If we truly ever want something like that then we need to have isolated class loading bound to JNDI proxies, so that a proxy will use the right client class versions.

It is never going to work if you don't plan for it. Customers will ask for this, and in fact many will expect this to work, so prepare a workaround for 4<->5 and put it in your roadmaps for 5<->6 :-) I mean it might be hard to do it between 4 and 5, but between 5 & 6 where the codebase is uniform it should be easy to make it work without isolated classloading. /D > > Carlo > > On 10/29/2009 06:54 PM, Dimitris Andreadis wrote: >> A user is trying to call ejb3 beans from AS 5.1 -> AS 4.2.3 >> http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4263032#4263032 >> >> I believe we do not cover this scenario in our compatibility matrix >> tests?

Doubt it, especially if EJB3 does start using Remoting 3 for 6. Though I
imagine that R3 could be backported into 4 or 5 if one were sufficiently motivated, I'm not so sure about the EJB3 side. :-) - DML On 10/30/2009 03:31 AM, Dimitris Andreadis wrote: > Carlo de Wolf wrote: > > Calling EJB3 beans over major releases doesn't work. > > If we truly ever want something like that then we need to have isolated > > class loading bound to JNDI proxies, so that a proxy will use the right > > client class versions. > > It is never going to work if you don't plan for it.

I disagree. There was large discussion in the past on this topic, and the consensus was that the community releases would favor delivering innovation rapidly over ensuring backwards compatibility. True wire compatibility between major revs is a non-trivial engineering effort. -- Jason T.
