[jboss-user] [Tomcat, HTTPD, Servlets & JSP] - How to implement JGroups-RMI Clustering in Tomcat

[sivasharma]

Hai!

I had tried to replicate my RMI Server using JGROUPS in the following manner. 

RMI Server running in one node with rmireplicated code using jgroups api (downloaded from soucreforge.net) and Tomcat server running on
another node. I had copied replicated rmi class files from RMI Server and pasted it into a WEB-INF/classes directory. 
First I had started the RMI Server. It displayes message as Become Group Coordinator found in Remote Home.

Then I had started the Tomcat server and call my apllication using IE. When a client contacts the RMI Server it shows error..

 
RMI Side

[WARN] UDP - -packet from /172.178.100.79:3747 has different version ( ??") from
 ours (0227). This may cause problems
