Example/ Start Process via Application

[Christian]

Hi,

I'm looking for a camunda example application.
The examples (twitter, invoice etc.) start in the camunda UI tasklist:
http://localhost:8080/camunda/app/tasklist/.

Any example there the process starts via application and not via tasklist?

[Sebastian Menski]

Hey Christian,

what application do you mean? Do you mean a process application or another external application?

If you mean a process engine you could use the RuntimeService.

processEngine.getRuntimeService().startProcessInstanceByKey("testProcess");

If you have an external application you can use the REST API to start a process.

Cheers,

Sebastian

Hi Sebastian,

I want to make use of the Java API, so currently no REST API.

Is there any example to see it all working together?

Hi Christian,

You can start a process inside a method of your application like so

HashMap<String, Object> variables = new HashMap<String, Object>();
long customerId = 01234566;
variables.put("customer", customerId);

ProcessEngine defaultProcessEngine = BpmPlatform.getProcessEngineService().getDefaultProcessEngine();
RuntimeService runtimeService = defaultProcessEngine.getRuntimeService();
ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("testProcess", variables);

Be sure to import the camunda-engine jar in provided scope in maven.

Cheers,
Christian
