Is modjk the same as AJP? If so, we have this configuration:
JBOSS 3.2.1 Tomcat 4.1.24 integrated
We had problems with session replication if stickiness was OFF. To solve the problem we had to keep stickiness ON. You may wish to investigate this as a solution to your problem.

# Define 1 real worker using ajp13
# Set properties for loadbalancer
# Set properties for worker1 (ajp13)
# Set properties for worker2 (ajp13)
But we have the same problems.
