Integrating jBPM 5 and Drools 5 runtimes as part of a web based application

• How to integrate jBPM 5 and Drools 5 runtime as part of a Web Application?
  Basically, it is good to have some small examples which can demonstrate executing a sample Business Rule or a BPMN2 Process from within a web based application (may contain JSP or Servlets) which can be deployed in a container like JBoss EAP.
