Spring Session Replication Problem

I've currently researching in load balancing my Spring project. I've used Apache web server as front-end to multiple Tomcat instances. I've used mod_jk for the load balancing. When I run it, if I shutdown one server, i had to login again to the system. Previously I also tried it in simpler example with the Tomcat's session example program and the session replication worked fine.

This is my configuration for the Apache's httpd.conf mod_jk part:

LoadModule jk_module modules/mod_jk.so

JkWorkersFile conf/workers.properties
JkLogFile logs/jk.log
JkLogLevel debug
JkLogLevel info
JkLogStampFormat "[%a %b %d %H:%M:%S %Y]"
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
JkRequestLogFormat "%w %V %T"

JkMount /test balancer <-- this is the spring program
JkMount /test/* balancer <-- this is the spring program
JkMount /jk_status status`

And this is my workers.properties setting:

workers.tomcat_home=/worker1
workers.java_home=$JAVA_HOME
ps=/

worker.list=balancer,status

worker.worker1.port=8009
worker.worker1.host=localhost
worker.worker1.type=ajp13
worker.worker1.lbfactor=1

worker.worker2.port=8109
worker.worker2.host=localhost
worker.worker2.type=ajp13
worker.work开发者_如何学编程er2.lbfactor=1

worker.balancer.type=lb
worker.balancer.balance_workers=worker1,worker2
worker.balancer.method=B
worker.balancer.sticky_session=1

worker.status.type=status

And I've put a sample of one of my tomcat's server.xml here: http://pastebin.com/0j0ta2WA

I've also added <distributable/> tag to my application's web.xml. Is there something I missed here that made the session replication not working?

• Tomcat 5.5
• Apache 2.2
• mod_jk
• Spring 2.5.6
• JDK 1.6.0_01

Do you have a jvmRoute defined in your server.xml? Here are the docs: http://tomcat.apache.org/tomcat-5.5-doc/config/engine.html I would have looked at your server.xml but the link is wrong.
