Get processDefinition tasks , start event, end event using Java, without creating a process instance

[mansi]

Hi,
My requirement is to get the details about deployed processDefinition, like Tasks in it, its StartEvent, EndEvent.
But I want to have these without creating a process instance.
Is there a way to achieve this?
I have been looking into activiti user guide as well as javadocs, but couldn't find a way.
Any help will be appreciated. Thanks.

Hi Mansi,

have a look on the following jUnit test in the activiti source:
org.activiti.engine.test.bpmn.event.end.TerminateEndEventTest#testParseTerminateEndEventDefinitionWithExtensions

Hey, Thanks a lot, I looked into that test and was able to proceed with my task.

I also want to know if there is some way to update a processDefinition after creating it once.
Thanks.

Hi Mansi,

I do not know about such a possibility in activiti5 (it could be supported in the activiti6).

Okay thanks again.

I have one more question:
Is there a way to create a process definition without specifying configuration in an xml file, instead specifying it programatically?

[martin_grofcik]

Hi,

You can deploy process definition with org.activiti.engine.RepositoryService#createDeployment and deploy the deployment afterwards.

So ultimately it will need the xml file right? when we will deploy it?

[jbarrez]

BPMN 2.0 is an XML standard, so yes.
The alternative is creating it in java (see the BpmnModel approach in the class that Martin mentions above).

Hey, Thanks a lot will look into it.

Hello, I found that after creating a process using BpmnModel, it has to be converted to xml for deployment, is that correct? Or is there any other way of doing it?
