JBPM is such a supporting technology. It offers a process automation engine that knows how to interprete business process markup languages such as jPDL and BPEL.
jBPM is a framework for graph oriented (business process) programming. It gives you Node, Transition, ProcessDefinition and Action classes to work with, and provides a lot of infrastructure, like persisting a process instance to a database when the process instance has to wait for human interaction.
Ideally, a business process analyst will model a business process in jPDL or BPEL, after which a developer will put logic(insert Actions, Tasks, etc..) in the placeholders of the nodes and the transitions of the process definition.
In other words, the developer adds an actual implementation, like take the input from a user on a webpage, do a query on/write to a database, send a message to a JMS-bean or call a method on a webservice.
In other words, jBPM is a framework with which we can organise our building blocks(database tables, services, views,..) in a business process graph
