Hello,
I have followed the steps given in the docs for clustering web applications
.But failover doesnt work with 2 servers.
The 2 servers are running on different machines.I have installed apache with
mod_jk on both the machines.
when I shut down my server with the other server running and try to access the
web application by using localhost:port/samplewebapp , it gives page cannot be
displayed error.
I have changed theRMi port on the other server to 11099 whereas the RMI port in
my machine is 1099.Is that a Pblm?
I am sending the properties and config files.Please let me know if there are
any errors in the configurations
mod-jk.conf
