Class DABridgeServlet

java.lang.Object
  javax.servlet.GenericServlet
      javax.servlet.http.HttpServlet
          com.programix.da2.bridge.http.DABridgeServlet

All Implemented Interfaces:

Serializable, Servlet, ServletConfig

public abstract class DABridgeServlet
extends HttpServlet

This is the servlet half of the HTTP bridge (see HttpDABridgeProcessor). This servlet does not enforce any security or session tracking and passes along all requests to the DABridgeProcessor specified during initialization (that processor is in charge of any security policies). Subclasses must implement the setup() method and in this method, they must call setProcessor(com.programix.da2.bridge.DABridgeProcessor).
