Thanks for Allen's advice. I am new user for JBoss and still study to use it. My first step is to setup a simple environment that achieve all I need. Then, further step is HA (cluster, failover,...etc). I spent a little bit time to read about the cluster of JBoss. The documentation is not clear to show the steps to setup the clustering. I hope JBoss can have a simple clustering setup example steps by steps. If you have simple steps to setup simple clustering, please let me know. Thanks.
