OpenSymphony Workflow is a very flexible workflow system that can be plugged in to almost any need or existing application. Uses can range from document management to order processing to project management. It includes support for many different interface mechanisms (SOAP, EJB, Java Class) as well as persistence (EJB, JDBC, XMl, Ofbiz). It works in any J2EE container, including servlet containers (without EJB support).
