Tomcat 6 clustering problem...rltd to context path
*I have two tomcats (tomcat 6)** setup on two separate machines. I have a
hardware load balancer with scheduling method configured to round robin.*
**
*each tomcat recognizes the other one by saying replication member added *
**
*I also made the "examples" web application (that comes with tomcat) a
cluster aware application. For this "examples" application, session
replication and everything works fine. This is how the log shows for this
application.*

Re: Tomcat 6 clustering problem...rltd to context path
Posted by rohit aman <ro...@gmail.com>.
Thanks for the reply...
The app is installed on node 2 as well. But, for some reason it looks at
the context path localhost#/ea where as the app is at localhost#/ ..... So,
Somehow I need to tell tomcat to look at localhost#/ instead of
localhost#/ea.... Any input is appreciated...Thanks
