title: Intercommunication between two wars in Tomcat
body: <p>I have a fundamental question, is it possible to communicate between two wars which are running on same instance?</p>
  
  <p>Another way, suppose Thread A [daemon] is running/initiated from A.war, and Thread B [daemon] is running/initiated from B.war, both wars are deployed in same tomcat instance.
  Can I communicate between Thread A to Thread B? If so, how it's possible [link to tutorial]?</p>
