Track the process like JBPM4

weiyi2011

Hi, everybody.

I want to track the process like JBPM4.

JBPM4:

// get ID from jsp page
String id = ActionUtil.getParameter("piId");
      
ProcessEngine pe = Configuration.getProcessEngine();
RepositoryService ps = pe.getRepositoryService();
ExecutionService es = pe.getExecutionService();
      
// query the process instance
ProcessInstance pi = es.createProcessInstanceQuery().processInstanceId(id).uniqueResult();
String pdId = pi.getProcessDefinitionId();
Set<String> names = pi.findActiveActivityNames();
      
// get the coordinate of acitivity
ActivityCoordinates ac =  ps.getActivityCoordinates(pdId,names.iterator().next());
System.out.println(ac.getX() +"\t" +ac.getY());
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Activiti5:[something I try]

ProcessDefinition processDefinition = repositoryService.createProcessDefinitionQuery()
            .processDefinitionKey("leave2")
            .list()
            .get(0);
       
ProcessDefinitionImpl pdImpl = (ProcessDefinitionImpl) processDefinition;
/**
 * ??? ProcessDefinitionImpl.getInitial is null
 */
ActivityImpl actImpl = pdImpl.getInitial();
System.out.println(actImpl.getX() +"\t" +actImpl.getY());
       
ExecutionEntity execution = (ExecutionEntity) runtimeService.createExecutionQuery()
             .executionId("101")
             .singleResult();

/**
 * ??? execution.getActivity() is null
 */
actImpl = execution.getActivity();
System.out.println(actImpl.getX() +"\t" +actImpl.getY());
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Can you show me the way? Thanks very much.

The ProcessDefinition returned by the query had no ActivityImpl initialized, use this (not exposed on public API) instead:

<br>ReadOnlyProcessDefinition def = ((RepositoryServiceImpl)repoService).getDeployedProcessDefinition(processDefinitionId);<br>

Also, Activiti offers the process-instance visualisation in activiti Probe, or through the REST-API:

I try these code. But I found all of them return the value is -1.

What's the matter? Why all coordinates is -1?

<br>// Graphical information<br>protected int x = -1;<br>protected int y = -1;<br>protected int width = -1;<br>protected int height = -1;<br>

this is init value, but I want to get the coordinate the same as XXX.activiti.

Thanks again.

These values are filled in during parsing, IF your process has Diagram interchange information (eg. when using Activiti Modeler or Designer)

Hi, jbarrez.

I haven't got your point. Can you explain more particularer?

Show me some java CODE.

Thanks a lot.

See http://activiti.org/userguide/index.html#generatingProcessDiagram

Your process must contain informations such as <bpmndi:BPMNShape … etc. Those will automatically be produced by the modeler and designer.

Hi, jbarrez.

I design my process by eclipse Designer and not signavio.

http://activiti.org/userguide/index.html#generatingProcessDiagram

In case no image is provided in the deployment, as described in the previous section, the Activiti engine will generate a diagram image when the process definition contains the necessary 'diagram interchange' information. This is the case when using the Activiti Modeler (and in the near future when using the Activiti Eclipse Designer).

Which version are you using? DI information was added in the last (5.2) release.

Could you please upload your process so we can take a look?

Hi, jbarrez.

Yes. I use activiti5.1. And I create a new activiti by version 5.2, It work well.

Thanks very much.
