To view the discussion, visit: https://community.jboss.org/message/752576#752576 -------------------------------------------------------------- Hi Srikanthan,      I have done the web application  interaction with JBPM. In our example It was covered around 70% of your requirement.      We can have the helper class to call the JBPM process or with in the servlet we can have the call to JBPM process. And also covered Human tasks and actions .      sample code (Servlet) : ***protected ** * **void** processRequest(HttpServletRequest request, HttpServletResponse response) **throws** ServletException, IOException { response.setContentType( "text/html;charset=UTF-8");PrintWriter out = response.getWriter(); **try** {String action = request.getParameter( "action"); **if** (action.equals("CreateProcess")) { UserTransaction ut = (UserTransaction) **new** InitialContext().lookup( "java:comp/UserTransaction" );ut.begin(); //StatefulKnowledgeSession ksession = JbpmAPIUtil.getSession(); // JPAWorkingMemoryDbLogger logger = **new** JPAWorkingMemoryDbLogger (ksession); /*Map<String, Object> params = new HashMap<String, Object>();params.put("priority", "High"); params.put("modelNumber", "123"); params.put("quantity", "66"); */ KnowledgeRuntimeLoggerFactory.+newConsoleLogger+( ksession); ksession.getWorkItemManager().registerWorkItemHandler("Log", **new** SystemOutWorkItemHandler()); ksession.getWorkItemManager().registerWorkItemHandler( "Email", **new** EmailWorkItemHandler("20.139.68.11","86400","lsundari","Shiva@2012")); //ksession.getWorkItemManager().registerWorkItemHandler("Human Task", new WSHumanTaskHandler());
