    Invoke jBPM workflow from external app

    Ashish Chawla Newbie

      Hi All,
      I am trying to figure out how can I invoke a jBPM workflow from an external java application because as per my understanding someone has to invoke the start state and then the flow can pass through.

      Here is the processdefinition.xml

      <?xml version="1.0" encoding="UTF-8"?>
      
      <process-definition xmlns="urn:jbpm.org:jpdl-3.2" name="http-demo-process">
      
       <swimlane name="initiator">
       <assignment actor-id="manager" />
       </swimlane>
       <start-state name="start-state1">
       <task swimlane="initiator" />
       <transition to="node1"></transition>
       </start-state>
       <node name="node1">
       <action class="com.sample.action.MessageActionHandler">
       <message>Sending Message</message>
       </action>
       <transition to="end-state1"></transition>
       </node>
       <end-state name="end-state1"></end-state>
      </process-definition>


      If I deploy this code to jbpm-console i can login as a user and invoke this workflow, but instead what i want to do is write a separate java application (public static void main) from which I can invoke this workflow...

      Any examples, sample code, links, docs etc will be very helpful...

      Thanks

          Hi there,

          I wrote the following class, which will invoke a workflow process. I use this from a servlet which takes normal xml over http (not soap) and then calls the process with the parameters.

          /**
           *
           */
          public class WFProcessFactory {
          
           JbpmConfiguration jbpmConfig = null;
          
           /**
           *
           * @param processId
           * @param processName
           * @param key
           * @param processVariables
           * @param signalStart
           * @return
           */
           public long startProcess(long processId, String processName, String key, HashMap processVariables, boolean signalStart) {
           long tokenId = 0;
          
           if (jbpmConfig == null) {
           jbpmConfig = JbpmConfiguration.getInstance();
           }
           JbpmContext jbpmContext = jbpmConfig.createJbpmContext();
           try {
           // get the session and process definition according to the process id
           GraphSession graphSession = jbpmContext.getGraphSession();
          
           ProcessDefinition processDefinition = null;
           if (processName.length() > 0) {
           processDefinition = graphSession.findLatestProcessDefinition(processName);
           } else {
           processDefinition = graphSession.getProcessDefinition(processId);
           }
          
           // if there are no process variables, then create an empty variable list
           if (processVariables == null) {
           processVariables = new HashMap();
           }
           // startup the process, set its business key (for correlation purposes, and
           // signal it to start going with the flow
           ProcessInstance processInstance = processDefinition.createProcessInstance(processVariables);
          
           processInstance.setKey(key);
           tokenId = processInstance.getRootToken().getId();
           if (signalStart) {
           processInstance.signal();
           }
           } finally {
           jbpmContext.close();
           }
           return tokenId;
           }
          }
          


          The XML that I post to my servlet looks something like this.

          Input:
          
           <launch_workflow>
           <process_id>401</process_id> OPTIONAL if process_name is specified
           <process_name>SomeProcessName</process_name> OPTIONAL if process_id is specified
           <process_key>401_00001</process_key>
           <process_input>
           <process_var>
           <var_name>item1</var_name>
           <var_value>value1</var_value>
           </process_var>
           <process_var>
           <var_name>item2</var_name>
           <var_value>value2</var_value>
           </process_var>
           <process_var>
           <var_name>item3</var_name>
           <var_value>value3</var_value>
           </process_var>
           <process_var>
           <var_name>item4</var_name>
           <var_value>value4</var_value>
           </process_var>
           </process_input>
           </launch_workflow>
          
          
          Output:
          
           <launch_result>
           <token_id>499</token_id>
           </launch_result>
          


          One thing to take note of: Don't re-instantiate the JBPMConfiguration object with each call, as this causes the server to run out of memory really quickly.

          I hope that this helps.

          Regards

            Hi hmuller,
            I am still not able to use this with the servlet also. I used the sample which you provided and created a servlet and deployed it...but then also i am getting an error

            couldn't parse jbpm configuration from resource 'jbpm.cfg.xml'


            I am using Netbeans for my deployment of servlets and have configured the default server as jboss under the jbpm-suite path.

            Also now when i try to start the jboss server using
            run.bat -c jbpm


            I am not able to do that and its giving me errors, JbpmDS not bound.

            Please provide your inputs on how to get this deployed and working ...

            thanks

              hi Ashish,

              Were u able to solve this problem (couldn't parse jbpm configuration from resource 'jbpm.cfg.xml')?
              If yes, can you provide me with the steps.
              I am trying to call it from external java standalone program.

              Any help will be greatly appreciated.

                it is all just classpath issues.... the config file has to be available

                    Hi HMuller.

                    I too am doing the same thing, only difference is I am using a bpel process to be invoked.

                    I am using the same code. But I am getting this error.

                    Have you seen this any time. If so what must be wrong ?

                    org.jbpm.JbpmException: token 'Token(/)' can't be signalled cause it is currently not positioned in a node

                      Have you guys been able to figure it out yet?

                      Let me know if not, I can send you a sample code to look at.

                      Thanks

                            basically I have commented JTA transaction properties and CMT transaction properties. I am unaware of the implications.
                            Can someone throw some light on it.
