Invoke jBPM workflow from external app

[chawlaashish26]

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
Ashish

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.

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
ashish

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.

Ruchika

[kukeltje]

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

Hello,

Thanks for reply.
I try adding 'jbpm.cfg.xml' in class path but i am getting same error.
Below is the complete error stack trace:

I am not sure what I am missing.

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

thanks

Hi Ruchika/Dhanush,
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

not yet man.. any help is appreciated

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