Service endpoints are stateless and most likely beeing accessed over HTTP transport. What is your specific issue with load balancing the endpoint?
we want to make the web service highly available with a simple load-balancing . One way we explored is to use the apache modjk in the front-as suggested in jboss docs. But this leads to a single point of failure. What if apache goes down ??
No end to avoiding the single point of failure in the front. The key here is to distribute the request processors to keep the system healthy and take chances on the request dispatchers, as they do *not* do the bulk of processing.
