How to get process definition id in service task?

[kesavkolla]

I've a service task which implements JavaDelegate.  I want to get the current running process definition id.  Is there any API which returns the current process definition id?

I'm trying

runtimeService.createProcessInstanceQuery()
               .processInstanceId(executionContext.getProcessInstanceId()).singleResult().getProcessDefinitionId();
‍‍‍‍

and is failing with NPE.  This is very first task in my process.

I found the answer what I was looking.  I'm using Context to retrieve that information.


Context.getExecutionContext().getProcessDefinition().getId()


[ssrajesh74]

List <ProcessDefinition> ls = processEngine.getRepositoryService().createProcessDefinitionQuery().processDefinitionKeyLike("testprocess").latestVersion().list();
   String processDefinitionId = ls.get(0).getId();

Hello,

I have very similar situation:


        for (ProcessInstance prins : mainProceList) {
            if (prins != null && prins instanceof ExecutionEntity ){
              ProcessDefinitionImpl def = ((ExecutionEntity) prins).getProcessDefinition(); //…..
…
           }
…

one .getProcessDefinition() I get NPE:

java.lang.NullPointerException
at org.activiti.engine.impl.persistence.entity.ExecutionEntity.ensureProcessDefinitionInitialized(ExecutionEntity.java:662)
at org.activiti.engine.impl.persistence.entity.ExecutionEntity.getProcessDefinition(ExecutionEntity.java:647)
…..

If I have current ProcessInstence how to get process definition? It's possible get proce.definition avoiding repositoryService nad additional querying?

From within a servicetask?

No, not in service task Delegate implementation.
