javax.servlet.http.HttpServlet
   de.danet.an.workflow.clients.wfxml.Servlet

Servlet
public class Servlet extends HttpServlet (Code)
This class provides an interface between the workflow engine (i.e. its processes and any HTTP based client (e.g. Web browser application).

The servlet works as a mediator for services of the different roles, excluding the observer, as they are defined by the Wf-XML 2.0 standard.
