    Fail Over of an Web App

    Thorsten de vos Newbie

      Hi All,

      our Cluster looks like the following: Two JBoss AS 4.2.3 with Portal 2.7.1 (clustered binaries) behind two Apache LoadBalancers 2.2.3 with mod_JK 1.2.18.

      The Loadbalancing is workinging fine. But I hava a problem with the Failover. If I'm in a WebApp and then shutdown the Jboss I'm working on I will not be able to work on the second Jboss.

      In short terms: Both are started up successfully and build a cluster. Then I browse to any webapp for example in the administration area of the portal. Then I shut down the Jboss I'm now working on and I want to switch to another Tab (in the admin area from portlet-Instances to portlet-definitions) then I got the following:

      If I reload the WebApp, I have now issues, just when I follow up my original session...

      This happens in the portal and with selfmade WebApps builded for running in a cluster... So I think this is a general error in configuration, maybe the loadbalancer, or what ever. At this point I'm out of ideas on how to get this work...

      Thanks in advance for reply.

      Regards
      Thorsten
