Pete Muir updated WELD-59:
--------------------------

    Fix Version/s: TBC
                       (was: 1.1.0.CR1)


Issues in JBoss EJB 3 mean that we can't test Weld in a cluster. We are aiming 
to get these EJB3 issues resolved for AS 6, but that is not certain (I have 
pleaded ;-). So slipping this to TBC for clarity.

> Clustered WebBeans, no support for sessionscoped (and higher) replication

> From what I can tell, this is what happens.
> Assume you have a 2 node environment w/ apache httpd + mod_jk in front of the 
> jboss servers, used to limit servers exposed + a loadbalancer (F5 ASM) in 
> front of those.  The apache servers are only configured to talk to one jboss 
> server each (httpd + jboss are on same box, they only talk to the local 
> client).  the f5 serving the initial request is configured for pure round 
> robin (no cookie persistence) and as a result request 1 could go to server 1 
> and then request 2 goes to server 2.
> Now assume that the two jboss servers are clustered together, the EJBs are 
> clustered and have a cache policy (based on the JBoss annotations).  They 
> only have local interfaces.  In addition, there are some classes that are 
> only POJOs; but they sit in the ejb module.  Based on what's happening these 
> objects should be replicated as part of the HTTP session state.
> A few problems seem to occur when the request goes to the second server after 
> the first request goes to the first server.
> 1. References to the resources required by the EJBs are not injected in the 
> second server.  This includes members decorated @Resource or 
> @PersistenceContext
> 2. References to EJBs required at the view level are not restored.
> In addition, concurrent modification exceptions seem to be more likely when 
> deployed like this, resulting in having to downgrade EJBs to POJOs in order 
> to remain stateful.
