Unable to make a REST calls to jbpm-console

[Mahesh Vibhute]

Hello jBPM gurus,

I have created a sample workflow using the KIE workbench, and now I am trying to make a REST call to trigger this workflow.

While some simple REST calls are successful (eg.: http://localhost:8080/jbpm-console/rest/deployment/com.my.own:CoverageAndVisibility:1.0/), the call to start a process is failing with the below error.

Has anyone encountered this or knows how to resolve?

Hi,

To start process instance using REST API you have to use following API
~~~
/runtime/{deploymentId}/process/{procDefID}/start
~~~

Refer guide for more details on REST API.

Since the execute command already contains the deployment id, it's no longer necessary to specify this as part of the url:
http://server:8080/business-central/rest/execute
