Deploying a process programatically

[P]

Hi,

I'm reviewing Camunda for integrating it in our environment, but I'm a bit stuck early on in the process.

I've included the required jars on the classpath (not getting any classNotFound errors), and created a processEngine:
ProcessEngineConfiguration.createStandaloneInMemProcessEngineConfiguration().buildProcessEngine();

Next I create a modelInstance and deploy it:
BpmnModelInstance modelInstance = Bpmn.createExecutableProcess('ExampleProcess')
.name("Example process")
.startEvent()
.userTask()
.name("Some work to do")
.endEvent()
.done();

File file = java.io.File.createTempFile("bpmn-model-api-", ".bpmn");
Bpmn.writeModelToFile(file, modelInstance);

processEngine.getRepositoryService().createDeployment()
.name('test-2')
.addInputStream("FluentTest", new java.io.FileInputStream(file))
//.addModelInstance("FluentTest", modelInstance) //Also tried this variant, but same issue
.deploy()

After running this code, which raises no errors, I'm logging the following:
log.debug(processEngine.getRepositoryService().createProcessDefinitionQuery().processDefinitionId('ExampleProcess').list())
log.debug(processEngine.getRepositoryService().createDeploymentQuery().deploymentName('test-2').list())

Which gives me:
DEBUG []
DEBUG [DeploymentEntity[id=1, name=test-2, resources=null, deploymentTime=Fri Aug 01 13:06:31 CEST 2014, validatingSchema=true, isNew=false]]

So, my conclusion is that the proces "ExampleProcess" in my deployment is not available. Where am I going wrong?

Hope someone can share some insight,

Regards,

Paul

Hi Paul,

two things:

  //.addModelInstance("FluentTest", modelInstance) //Also tried this variant, but same issue

should be changed to 

  .addModelInstance("FluentTest.bpmn", modelInstance)

And this

   log.debug(processEngine.getRepositoryService().createProcessDefinitionQuery().processDefinitionId('ExampleProcess').list())

should be changed to

   log.debug(processEngine.getRepositoryService().createProcessDefinitionQuery().processDefinitionKey('ExampleProcess').list())

See also: http://docs.camunda.org/latest/guides/user-guide/#process-engine-process-engine-concepts-keys-and-versions

Does this help you?

Excellent! Now it works.

In my attempts I had also tried "processEngine.getRepositoryService().createProcessDefinitionQuery().processDefinitionKey('ExampleProcess').list()", but that didn't return anything either.

The main issue was the missing ".bpmn" in the resource name. Didn't find that anywhere in the docs.

Tnx for your quick response
