You should read the documentation and ask a more specific question. However I do not think that there are a lot of BPEL engine users. http://docs.jboss.com/jbpm/bpel/v1.1/userguide/ You should also take a look at Riftsaw (https://www.jboss.org/riftsaw) since the jBPM BPEL engine is not an BPEL 2.0 compliant engine. As far as I understood the developers of jBPM the BPEL engine is discontinued and they are intentions to work towards the integration of support for Riftsaw.
