Hi,
I am trying to load balance JBoss servers(jboss 4.2.2) with session replication on windows.
I have tried using mod_jk(version 1.2.27) as connector, but unable to connect apache http server(version 2.2.13) to jboss server.
I have successfully load balanced jboss servers with mod proxy, but no session replication in this case.
Kindly help me to load balance servers using mod_jk as well as replicating session in case of mod proxy.
Settings for mod_jk :
I have done the following settings in httpd.conf:
LoadModule jk_module modules/mod_jk.so
Include conf/mod-jk.conf
In mod-jk.conf file:
JkWorkersFile conf/workers.properties
JkShmFile logs/mod_jk.shm
JkLogFile logs/mod_jk.log
JkLogLevel info
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
JkOptions +ForwardKeySize +ForwardURICompat –ForwardDirectories
JkRequestLogFormat "%w %V %T"
JkMount /* loadbalancer
<Location /jkstatus/>
JkMount status
Order deny,allow
Deny from all
Allow from 127.0.0.1
</Location>
In workers.properties file:
worker.list=loadbalancer,status
worker.node1.port=8012
worker.node1.host=172.17.88.53
worker.node1.type=ajp13
worker.node1.lbfactor=1
worker.node1.cachesize=10
worker.node1.redirect=node2
worker.node2.port=8012
worker.node2.host=172.17.88.46
worker.node2.type=ajp13
worker.node2.lbfactor=1
worker.node2.cachesize=10
worker.node2.redirect=node1
worker.loadbalancer.type=lb
worker.loadbalancer.balance_workers=node1,node2
worker.loadbalancer.sticky_session=1
worker.status.type=status
The error that comes in apache server’s log file is : No connection could be made because the target machine actively refused it.

But when I used mod_proxy, I was able to load balance JBoss servers but unable to replicate session.
I did the following settings in httpd.conf for load balancing:
ProxyRequests On
ProxyVia On
ProxyPass / balancer://mycluster/
<Proxy balancer://mycluster>
BalancerMember
https://172.17.88.46:8444 smax=10
BalancerMember
https://172.17.88.53:8444 smax=1 loadfactor=20
</Proxy>
----------------------------------------------------------------------------------------------------------------------------------------------
JBoss settings :
In server.xml : <Engine name="jboss.web" defaultHost="localhost" jvmRoute="node1">
In web.xml : added the tag : <distributable/>
In jboss-web.xml : added the following cluster configuration :
<replication-config>
<replication-trigger>ACCESS</replication-trigger>
<replication-granularity>SESSION</replication-granularity>
</replication-config>
In jboss-service.xml : <attribute name="UseJK">true</attribute>
I am able to load balance the servers successfully using mod proxy but unable to replicate session.
Kindly let me know if I am missing something…
