Hi,
I've been trying to setup a cluster and use mod_jk for loadbalancing. I
followed this tutorial :
http://wikis.sun.com/display/GlassFish/LoadBalanceMod_jkDemo , but
unfortunaly it's not workig for me.
I'm getting following exceptions when I try to deploy an application :
Cannot start container web

Any clue why this is happening ? When instead of creating a jk-listener I set
JVM option :
-Dcom.sun.enterprise.web.connector.enableJK=${AJP_PORT}, it seems to be
working. But I read somewhere that this method is now deprecated and I should
use the Network Listener. What's the difference anyway ?
And I have another question. I'm trying to achieve session replication in the
cluster. But when I try to test it and shutdown the instance to which I'm
currenly logged, with a new request I'm redirected to another instance with
new JSESSIONID and therefore my session data is lost. I managed to overcome
this by setting worker.instance-name.domain=domain1 for all the workers in
the workers.properties, but this seems to be causing some other issues. Is
this the right approach ? Do I have to set the domain attribute when I want
to get the session replication to work with mod_jk ?
I would be very grateful for any advice or suggestion.
