Starting a Process Through API

[dhanushgopinath]

Hi,

I understand that when a BPEL process is deployed the Application Server(AS) hosts the webservice to start that process, and we make a webservice call to that WS to start the process.

Is there a way to start the process through the API's ? Does ProcessDefinition class's createProcessInstance() method starts a process.

Please let me know your inputs.

Thanks in Advance

You can create a newProcessInstance with the JbpmContext.newProcessInstance() method...

[dhanushgopinath]

But it cannot receive any inputs right.

Suppose if my start activity is a , then how will I instantiate the input variable.

Is this actually possible?

Thanks
Dhanush

[salaboy21]

Yes, it is possible.
When you create a new ProcessInstance object the process not begin inmediately..
You can put your variables and then signal it to start.
Something like this:

ProcessInstance pi=JbpmContext.newProcessInstance("processname");
pi.getContextInstance().setVariable("var1", new Integer(1));
pi.signal(); -> this will start your process..

[dhanushgopinath]

No luck .. I got this exception.. Any inputs

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

[salaboy21]

Are you sure that you create a newProcessInstance???
Because look when this exception is thrown:

 if (node==null) {
 throw new JbpmException("token '" + this + "' can't be signalled cause it is currently not positioned in a node");
 }

This means that your actual node is null when you call the signal method.
Can you show us your process??
and the code that you are using to start it?

The process is this :

And the code is this :

JbpmConfiguration jbpmConfiguration = JbpmConfiguration
 .getInstance();
 JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext();
 BpelGraphSession graphSession = BpelGraphSession
 .getContextInstance(jbpmContext);

 BpelProcessDefinition bpelProcDef = graphSession
 .findLatestProcessDefinition("ProcessDefinitionName","ProcessDefintiion Target URI";

 ProcessInstance procInstance = jbpmContext.newProcessInstance("ProcessDefintionName");
 procInstance.signal();
 jbpmContext.close();

I am not currently setting any input variables, just wanted to see if its starts. I inspected the root token of the procInstance variable and found that its node is null.

[salaboy21]

I have no previously experience with jbpm-bpel, but first of all
you need to deploy your process first in order to do:

ProcessInstance procInstance = JbpmContext.newProcessInstance("ProcessDefintionName");

did you try with JbpmContext.deploy(BpelProcessDefinition)?

[dhanushgopinath]

The process is all deployed. The only thing in the code above is that i am trying to find the process def by the name and i do get it.

but start doesnt work

[dhanushgopinath]

Any updates? I would also like to know how to call a normal receive task through API's.

Thanks in Advance.

[salaboy21]

try to remove the following lines:

BpelGraphSession graphSession = BpelGraphSession
 .getContextInstance(jbpmContext);

 BpelProcessDefinition bpelProcDef = graphSession
 .findLatestProcessDefinition("ProcessDefinitionName","ProcessDefintiion Target URI";

if you have the process definition deployed the newProcessInstance method find your process definition and then you can signal it.

Also, are you sure that your process definition is correctly deployed?

[dhanushgopinath]

That also gives the same error. And the process def is for sure deployed. Other wise it wont create an instance of process def

I was looking into some stuff of code like this.

BpelGraphSession graphSession = BpelGraphSession
 .getContextInstance(jbpmContext);

 BpelProcessDefinition bpelProcDef = graphSession
 .findLatestProcessDefinition(procDEfPOJO.getProcessName(),
 procDEfPOJO.getProcessTargetNamespace().getUri());
//
// ProcessInstance procInstance = bpelProcDef.createProcessInstance();
// Token startToken = procInstance.getRootToken();
// startToken.signal();
 List listNodes = bpelProcDef.getNodes();
 Map mapNodes = bpelProcDef.getNodesMap();

 Set mapKey = mapNodes.keySet();
 Iterator keyIterator = mapKey.iterator();
 while(keyIterator.hasNext())
 {
 Object key = keyIterator.next();
 Scope obj = (Scope) mapNodes.get(key);
 List listNodes2 = obj.getNodes();

 for(int i=0;i<listNodes2.size();i++)
 {
 org.jbpm.graph.def.Node node2 = (org.jbpm.graph.def.Node) listNodes2.get(i);
 System.out.println(((Activity)node2).isInitial()); - PRINTS TRUE HERE
 if(node2 instanceof Receive)
 {
 Receive recieve = (Receive) node2;
 System.out.println(recieve.getName());
 }
 }
 }

And then

ProcessInstance procInstance = jbpmContext.newProcessInstance("Workflow1");
 procInstance.getRootToken().setNode(node2);
 procInstance.signal();

But the object node2 I am getting is a type of Sequence.

My Receive Task is inside a Sequence.

This much i am able to do.. so i think if i can get the receive activity Node and then set it on the root token it should work. This is just a guess though.
