Hi Nuno, I would think you have configured mod_jk to use worker1 as the only worker in apache. You should use the loadbalancer worker in mod_jk.conf like
JkMount /myapp/* loadbalancer and change your worker.properties to inlude the loadbalancer worker in the worker.list property like worker.list=loadbalancer,worker1,worker2 And I believe that you can remove worker1 and worker2 from that list if your are not accessing them directly from any JkMount directive.
