clustered statefull ejbs require HA-JNDI in colocated scenar

[new4jboss]

I have colocated web and business layers in each Jboss server and want to replicate HTTPSession instances throughout the cluster (to enable HTTP session fail-over). Furthermore, the session holds a statefull (clustered) ejb remote reference.

In this scenario must the remote reference be fetched from HA-JNDI or can it be retrieved from the local JNDI server, since I don't want load balancing anyway ?

Thank you in advance

Where you lookup a proxy should make no difference as the proxy is cluster aware independent of how its obtained.

Thanks for answering.

Interesting. I had this (wrong) idea that cluster aware stubs would only be available via HA-JNDI and that plain JNDI servers would still have old non-cluster aware stubs.

This raises another problem. In this colocated scenario, it makes no sense to redirect the request to another cluster node. How do I prevent load balancing from happening ?

Thank you

Look at the org.jboss.invocation.InvokerInterceptor. You can write a customized version to avoid distribution, or write a custom load balancing policy. If you care about where the calls are going, why is the bean clustered?

Hi

Ultimately, the bean is clustered to support clustering of an HTTPSession carrying a remote reference to it. Does this make any sense ?

Thanks

Well, does it make sense or not ? Anyone ?...

Yes, with a stateful session bean that makes sense.
