Thank u Martin.I could able to solve that exception now. but now iam getting NullPointerException. Below is the modified code and Exception .
| JbpmConfiguration jbpmConfiguration =JbpmConfiguration.parseResource("hibernate.cfg"); | JbpmContext jbpmContext=jbpmConfiguration.createJbpmContext(); | try{ | // parsing sub process | ProcessDefinition subProcessDefinition = ProcessDefinition.parseXmlResource("ChildProcess/processdefinition.xml"); | jbpmContext.deployProcessDefinition(subProcessDefinition); | System.out.println("subproceess Deployed "); | ProcessDefinition processDefinition = ProcessDefinition.parseXmlResource("MainProcess/processdefinition.xml"); | jbpmContext.deployProcessDefinition(processDefinition); | System.out.println("Main proceess deployed"); | | ProcessInstance processInstance = processDefinition.createProcessInstance(); | System.out.println(" a: "+ processInstance.getRootToken().getNode().getName()); | processInstance.signal(); | System.out.println(" b: "+ processInstance.getRootToken().getNode().getName()); | System.out.println("going to Process State now"); | processInstance.signal(); | System.out.println(" c: "+ processInstance.getRootToken().getNode().getName()); | System.out.println("reached to process State Now"); | | | System.out.println(" : "+ processInstance.getRootToken().getNode().getName()); | | processInstance.signal();// i expect , signal to end node of main process here. but i got the below exception. | System.out.println(" d: "+ processInstance.getRootToken().getNode().getName()); | | } | catch(Exception e) | {e.printStackTrace();} | finally{ | jbpmContext.close(); | } | And the exception is | java.lang.NullPointerException | at org.jbpm.graph.node.ProcessState.leave(ProcessState.java:197) | at org.jbpm.graph.exe.Token.signal(Token.java:194) | at org.jbpm.graph.exe.Token.signal(Token.java:139) | at org.jbpm.graph.exe.ProcessInstance.signal(ProcessInstance.java:251) | at com.iton.servlets.TestProcessState.doGet(TestProcessState.java:110) | at javax.servlet.http.HttpServlet.service(HttpServlet.java:697) | at javax.servlet.http.HttpServlet.service(HttpServlet.java:810) | at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:252) | at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) | at org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) | at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) | at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) | at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) | at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:178) | at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:175) | at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:74) | at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:126) | at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:105) | at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:107) | at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:148) | at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:869) | at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.ja | | at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:527) | at org.apache.tomcat.util.net.MasterSlaveWorkerThread.run(MasterSlaveWorkerThread.java:112) | at java.lang.Thread.run(Thread.java:595) | Plz tell me whats wrong in my code??
