title: Communication between rest services hosted on different tomcat servers
body: <p>I have a scenario where i am hosting different java Rest Services on different Tomcat instances (different machines). These projects running on the tomcats do not have any UI. For simplicity's sake, lets assume that the user will directly enter some URL in the browser (or curl) to avail these services. Now I need this service to be able to talk to (call functions) the services available in the other tomcat instance.<br>
  For eg. If TomcatInstance1 gets the call, and all this does is act as a 'router' to the different services, i want it to be able to place the Rest call for the other 'service' available on, say, TomcatInstance2. Is this possible?. If so, how to achieve that? (Tried searching for similar questions on SO, couldnt find any). Are there any online reference for the same?</p>
  
  <p>PS: Hosting the services in the same Tomcat Instance is against the requirement that I'm having. </p>
