org.itsnat.core.http
Class HttpServletWrapper

java.lang.Object
  javax.servlet.GenericServlet
      javax.servlet.http.HttpServlet
          org.itsnat.core.http.HttpServletWrapper

All Implemented Interfaces:

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

public abstract class HttpServletWrapper
extends javax.servlet.http.HttpServlet

Simplifies the development of new ItsNat based servlets.

New servlets may inherit from this class and overload init(javax.servlet.ServletConfig config) to setup the ItsNat infrastructure (default properties, register templates etc).

This class creates an ItsNatHttpServlet wrapping this servlet and forwards request/response calls to the ItsNatHttpServlet. Standard request and response objects are wrapped in HttpServletRequest and HttpServletResponse
