Hi,
I have a task node with two transitions and a task attached to it.The code is
as follows..
| <task-node name="HOD_Approval">
| <event type="node-enter">
| <action class="com.sample.action.ProcessAction"
accept-propagated-events="false"></action>
| </event>
| <transition to="Finance_Approval" name="Accepted"></transition>
| <transition to="end-state" name="Denied"></transition>
| </task-node>
Inside ProcessAction class I am accepting the decision from user and want to go
to the next transition accordingly..
| public class ProcessAction implements ActionHandler {
|
| private static final long serialVersionUID = 1L;
|
| public void execute(ExecutionContext executionContext) throws Exception
{
System.out.println("######################---------ProcessAction------------1-----------------######################
.");
| System.out.println("This Node
is---"+executionContext.getNode().getName());
| System.out.print("Enter your decission: ");
| BufferedReader br = new BufferedReader(new
InputStreamReader(System.in));
|
| String decission = null;
| try {
| decission = br.readLine();
| } catch (IOException ioe) {
| System.out.println("IO error trying to read your decission!");
| }
| System.out.println("Thanks for the desission, " + decission);
|
System.out.println("######################---------ProcessAction------------2-----------------######################
.");
| if(decission != null && decission.equalsIgnoreCase("a")){
|
|
System.out.println("######################---------ProcessAction----a--------3-----------------######################
.");
| executionContext.getTaskInstance().end("Accepted");
| }
| else if(decission != null && decission.equalsIgnoreCase("d")){
|
|
System.out.println("######################---------ProcessAction-----d-------3-----------------######################
.");
| executionContext.leaveNode("Denied");
| }
| else if(decission != null && decission.equalsIgnoreCase("c")){
|
System.out.println("######################---------ProcessAction-----c-------3-----------------######################
.");
|
| executionContext.leaveNode("checkBudget");
| }
| else{
| System.out.println("Error trying to read your decission!..Enter
only a/d ");
| }
|
| }
| }
|
With this the flow is navigating correctly to the next node as per the
decision, But after reaching end -state , again the process is selecting a
default transition ..where as it should stop, at end node..
The class I am using to invoke the jBPM is as follows..
| public class TravelProcessTest extends TestCase {
|
| public static void main(String args[])throws Exception {
| new TravelProcessTest().execute();
| }
| public void execute() throws Exception {
| JbpmConfiguration jbpmConfiguration =
JbpmConfiguration.getInstance();
| JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext();
|
| // Extract a process definition from the processdefinition.xml
file.
| ProcessDefinition processDefinition =
ProcessDefinition.parseXmlResource("simple/processdefinition.xml");
| //HashMap map = new HashMap();
|
| //map.put("travelDate",new Integer(100));
| //map.put("travelPeriod",new Integer(50));
|
| //Create an instance of the process definition.
| //ProcessInstance instance = new
ProcessInstance(processDefinition,map);
| ProcessInstance instance = new
ProcessInstance(processDefinition);
|
System.out.println("--------------------1-----------------######### .");
| displayStatus(instance);
|
System.out.println("---------------------2-----------------########## .");
| instance.signal();
|
|
System.out.println("---------------------3-----------------###########.");
| displayStatus(instance);
|
System.out.println("---------------------4-----------------###########.");
| instance.end();
|
|
| }
|
| private void displayStatus(ProcessInstance instance) {
| String nodeName = instance.getRootToken().getNode().getName();
| System.out.println("You are now in node: "+nodeName);
|
| }
| }
|
|
|
Can you please suggest what is going wrong.. so that even after reaching end
state , the process is again propagating to another transition..
