1 Web Server connecting to 2 JRun srvrs (failover, alternate boxes)

[Jay1Roy]

Hi guys,

I have trouble failing over two JRun3.1 servers. Following is the description, please help!
Scenario:
There are TWO instances of JRun on two different hardwares (with different IPs). There is a virtual IP that can point towards either of them when need be, like a crash of one server. While one server is UP the services on the other is stopped and the clustering software brings up/down the servers on either of the boxes.

The Problem
The clustering software works fine and starts the other server when one crashes but the issue is with the ejipt_objects.jar and ejipt_exports.jar which are server specific and have some hex numbers that are differnt in the two. My web server when tries to connect to the other JRun server in case of a crash, cant communicate and throws a "Stub mismatch" exception.

Request
Can anyone tell me how to have two JRun servers generate the exact stubs so that the switching of one JRun server to other is transparent to the webserver (like the IP is already by virtue of virtual IP).

Thanks in advance,

Roy.
