accessing the process/rules artifacts for headless integration

[Brahmeswara Yerrabolu]

I am new to jBPM and looking for help as below.

1. I would like to have a business process application with headless integration.

2. I would like to develop the main process (bpmn) and rules (DMN or Drools) using JBPM. Once done i would like these to be deployed and accessed via API.

I am looking for ways 

- to get the process/rules jar separately

- how to deploy this to jBPM (wild fly server)

Note: I am able to develop a process using business central and deploy using business central.  I am able to access the process using REST API.

I am looking to see if I can develop the process/rules using business central but take the JAR file and deploy this programmatically. 

appreciate any pointers/steps in this regard.
