title: Move servlets to jar file in purpose to use as library
body: <p>As I know it's rule to locate servlets in webapplication module. So after packaging we'll have war archive. 
  But later I need servlets to use like library. So as we cannot use war file as library i need the jar. </p>
  
  <p>The question: is it normall to refactor webmodule so that move servlets to other project(module) to package to jar archive and use it in webapp as dependency while compiling ?</p>
