[jboss-user] [JBoss jBPM] - JBPM : How to open web forms under a process flow

[anurag.yadav]

Hi,

  I am new to JBPM and tried it for some time to build a sample web application based on JBPM work flow. Now as i have different web forms attached with various nodes to take user input but when i am executing the process via java code (not on jbpm-console), the whole process executed simultaneously without opening any web form....
i had searched a lot over the net but didn't found any way out to open form via jbpm process.. is there any thing else required for this...

My process definition looks like this:
<?xml version="1.0" encoding="UTF-8"?>
  | <process-definition  xmlns="urn:jbpm.org:jpdl-3.2"  name="Appraisal">
  | 	<swimlane name="employee">
  | 		<assignment pooled-actors="anuragy,onkars"></assignment>
  | 	</swimlane>
  | 	<swimlane name="RO">
  | 		<assignment pooled-actors="sandeepg,vinayb"></assignment>
  | 	</swimlane>
  | 
  | 
  | 	<start-state name="Fill Appraisal Form">
  | 	<task name="Fill Appraisal Form">
  | 		<assignment pooled-actors="anuragy,onkars"></assignment>
  | 		<controller>
  | 			<variable access="read,write" name="ecode" mapped-name="E-Code"></variable>
  | 			<variable access="read,write" name="empName" mapped-name="Emp-Name"></variable>
  | 			<variable access="read,write" name="scheduleAdherence" mapped-name="Schedule Adherence"></variable>
  | 			<variable access="read,write" name="quality" mapped-name="Quality"></variable>
  | 			<variable access="read,write" name="effort" mapped-name="Effort"></variable>
  | 		</controller>
  | 	</task>
  | 	
  | 	<event type="node-leave">
  | 		<action class="com.demo.handler.FillAppraisalFormHandler"></action>
  | 	</event>
  | 		<transition to="Approve Appraisal Form"></transition>
  | 	</start-state>
  | 
  | 
  | 	<task-node name="Approve Appraisal Form">
  | 		<task name="Approve Appraisal Form">
  | 			<assignment pooled-actors="sandeepg,vinayb"></assignment>
  | 			<controller>
  | 				<variable access="read" name="ecode" mapped-name="E-Code"></variable>
  | 				<variable access="read" name="empName" mapped-name="Emp-Name"></variable>
  | 				<variable access="read" name="scheduleAdherence" mapped-name="Schedule Adherence"></variable>
  | 				<variable access="read" name="quality" mapped-name="Quality"></variable>
  | 				<variable access="read" name="effort" mapped-name="Effort"></variable>
  | 				<variable access="read,write" name="comment" mapped-name="Comment"></variable>
  | 			</controller>
  | 		</task>
  | 		<event type="node-enter">
  | 			<action class="com.demo.handler.GetAppraisalData"></action>
  | 		</event>
  | 		<transition to="End" name="Approve"></transition>
  | 		<transition to="Update Appraisal Form" name="Reject"></transition>
  | 	</task-node>
  | 
  | 	<task-node name="Update Appraisal Form">
  | 		<task name="Update Appraisal Form">
  | 			<assignment pooled-actors="anuragy,onkars"></assignment>
  | 			<controller>
  | 				<variable access="read" name="ecode" mapped-name="E-Code"></variable>
  | 				<variable access="read" name="empName" mapped-name="Emp-Name"></variable>
  | 				<variable access="read,write" name="scheduleAdherence" mapped-name="Schedule Adherence"></variable>
  | 				<variable access="read,write" name="quality" mapped-name="Quality"></variable>
  | 				<variable access="read,write" name="effort" mapped-name="Effort"></variable>
  | 				<variable access="read" name="comment" mapped-name="Comment"></variable>
  | 			</controller>
  | 		</task>
  | 		<transition to="Approve Appraisal Form"></transition>
  | 	</task-node>
  | 
  | 
  | 	<end-state name="End"></end-state>
  | 
  | 
  | 
  | </process-definition>
and my forms.xml looks like this:

  | <?xml version="1.0" encoding="UTF-8"?>
  | 
  | <forms>
  |   <form task="Fill Appraisal Form" form="Fill Appraisal Form.xhtml"/>
  |   <form task="Approve Appraisal Form" form="Approve Appraisal Form.xhtml"/>
  |   <form task="Update Appraisal Form" form="Update Appraisal Form.xhtml"/>
  | </forms>
  | 

and i am creating any process instance via this way:

  | 
  | 	public ProcessInstance startNewProcessInstance(String processDefinitionName) {
  | 
  | 		JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext();
  | 		try {
  | 			GraphSession graphSession = jbpmContext.getGraphSession();
  | 			ProcessDefinition definition = graphSession
  | 					.findLatestProcessDefinition(processDefinitionName);
  | 			if (definition != null) {
  | 
  | 			} else {
  | 				definition = deployProcessDefinition(jbpmContext,
  | 						processDefinitionName);
  | 			}
  | 			ProcessInstance instance = definition.createProcessInstance();
  | 			signalProcess(jbpmContext, instance);
  | 			return instance;
  | 		} catch (Exception ex) {
  | 			ex.printStackTrace();
  | 		} finally {
  | 			jbpmContext.close();
  | 		}
  | 		return null;
  | 	}

Please help!!!!!
