Have you defined the jvmRoute on your Engine element in tomcat's

E.g.,
The value for jvmRoute should match the route defined in your apache

Hello to all,
I am using Apache 2.2.21 & Tomcat 6.0.29
1) Schema: Load balancer (Apache.2.2.21) -> 1st appli (Tomcat 6.0.29)
-> 2nd appli. (Tomcat 6.0.29)

statefull (having a look at the logs).
