[jboss-user] [Clustering/JBoss] - Re: ejb proxies only contain nodes at deploy time

Ok, I'll try to explain. Whenever a change is made to the cluster, adding a node or one node dies, the client proxies aren't informed. If I'm correctly informed this should happen. Even jndi lookup results in the same proxies as before the change in the cluster config.

There is a webserver started on each server holding the java webstart client. Depending on which server is used to download the client the behavior is different as I described. The client calls stateless ejbs on the server and these are quite frequently looked up from jndi. The problem is that the resulting proxy only contains the nodes available to the server when it was deployed.

Here is some Ethereal capture made after Server1 (192.168.1.116) was shut down. This is part of the response from Server2

As I understand the proxy is informed that both server is still alive and it uses it numerous times, each time with a timeout that takes a long time to fail.

Even if this is a ha-jndi matter we are somewhat confused. The first problem when only one server is used may be because we only get the local jndi. But the other case where we get both servers in the proxy is weird. Shouldn't it catch the death of the other node and reflect it to the proxies?
