Writing Client to WAS Cluster

I have a WAS 6.0 Clustered environment setup. I have a client on a different box, outside of the WAS environment that is attempting to hit the cluster via EJB calls. Is it necessary to install the WAS Application Client to enable appropriate load balancing (I should note, that when we attempted to run a client without WAS Appl Client installed, it would NOT load balance at all, it would only hit one server)? Secondly, assuming the answer to the question above is yes, is it necessary to actually 'install' the application client, or is there a list of deployable jars that we can use instead of doing a formal install?

I do have the websphere horizontal cluster (Having Two Horizontal Nodes)in my project and the websphere plug-in (to be placed on web server) itself takes the great care of load balancing (Round-Robin). I don't think you need application client installation.

Hi

I am not sure if you can load balance ejb calls. You can see in memory-to-memory replication concept.

Terry,

In you client app are you passing both the bootstrap ports of the clusters members. Here is a good article on how EJB Calls operate and aslo an example.
