-------------------------------------------------

Hi [~pferraro]

I think ejb-client topology and ejb are separate concepts. The topology does not contain any information about what is deployed (just the info related to connect to that node). I think is posible to allow the topology to be sent independently if the singleton is deployed or not and let the ejb-client to query once one node is down. After all setting up the whole topology statically will throw the same result (most of the endpoint connections will be useless except one where the singleton is deployed)

> Given that an application contains a SLSB and is clustered, any EJB client will be updated to have a view off all cluster members and is able to use and failover to any node in the cluster no matter whether it is in the initial list of servers.
> Now if the application is marked as "singleton-deployment" via jboss-all.xml and deployed to all servers only one server in a cluster will pick it and make it active.
> Now the expectation is that a client is routed to that server no matter whether this special server is included in the clients initial connection list.
> The interesting thing is that the client.log show that both servers are connected it the application is NOT marked as singleton
> But only the initial server is connected if the app is marked as singleton!
