Answer 1

Quoting from wikipedia:

jBPM is an open-source workflow engine written in Java that can execute business processes described in BPMN 2.0 (or its own process definition language jPDL in earlier versions). It is released under the ASL (or LGPL in earlier versions) by the JBoss community.

Quoting from wikipedia:

A workflow engine is a software application that defines a process, the rules governing process decisions, and routes information. It is a key component in workflow technology and typically makes use of a database server.

The relationship:

jBpm is a flexible, extensible workflow management system. Business processes , expressed in a simple and powerfull language and packaged in process archives, serve as input for the jBpm runtime server. jBpm bridges the gap between managers and developers by giving them a common language : the jBpm Process definition language (jPdl).

Answer 2

1. JBPM is a good word for IT managers, a nightmare for programmers.
2. Do not use it. Jbpm full with bugs..
3. A workflow engine: https://en.wikipedia.org/wiki/Workflow_engine
