Class DwrServlet

java.lang.Object
  javax.servlet.GenericServlet
      javax.servlet.http.HttpServlet
          org.directwebremoting.servlet.DwrServlet

All Implemented Interfaces:

java.io.Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

Direct Known Subclasses:

DwrGuiceServlet, DwrSpringServlet

public class DwrServlet
extends javax.servlet.http.HttpServlet

This is the main servlet that handles all the requests to DWR.

It is on the large side because it can't use technologies like JSPs etc since it all needs to be deployed in a single jar file, and while it might be possible to integrate Velocity or similar I think simplicity is more important, and there are only 2 real pages both script heavy in this servlet anyway.

There are 5 things to do, in the order that you come across them:

• The index test page that points at the classes
• The class test page that lets you execute methods
• The interface javascript that uses the engine to send requests
• The engine javascript to form the iframe request and process replies
• The exec 'page' that executes the method and returns data to the iframe
