public abstract class NiggleServlet

extends javax.servlet.http.HttpServlet

The base Servlet class in the Niggle framework. Note that this class defines very little functionality. NiggleServlet delegates to 2 objects, NiggleConfig and ServletInteraction

public NiggleServlet()

Method Detail

init

public void init(javax.servlet.ServletConfig config)
          throws javax.servlet.ServletException

Servlet initialization. This routine just hands off to the NiggleConfig object that really takes care of initializing the framework.

Specified by:

init in interface javax.servlet.Servlet

Overrides:

init in class javax.servlet.GenericServlet

Throws:

javax.servlet.ServletException - thown if there is some problem initializing this servlet. Servlet will not be loaded.

NiggleConfig

doGet

public void doGet(javax.servlet.http.HttpServletRequest request,
                  javax.servlet.http.HttpServletResponse response)
           throws javax.servlet.ServletException,
                  java.io.IOException

By default, a Niggle servlet treats a GET and a POST identically. So this method, in this base class, simply invokes doPost()

Overrides:

doGet in class javax.servlet.http.HttpServlet

javax.servlet.ServletException

java.io.IOException

See Also:

doPost(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse)

doPost

public void doPost(javax.servlet.http.HttpServletRequest request,
                   javax.servlet.http.HttpServletResponse response)
            throws javax.servlet.ServletException,
                   java.io.IOException

This method implements the top-level flow of of control by which we handle a request. Essentially, we create a ServletInteraction object of the appropriate type (we rely on the niggleConfig object to do this.) Then we invoke the dispatch() method which carries out the logic implicit in the request. At the end, we invoke interaction.output() in order to output a page as a result of the request.

Overrides:

doPost in class javax.servlet.http.HttpServlet

javax.servlet.ServletException

java.io.IOException

getServletInfo

public java.lang.String getServletInfo()

Specified by:

getServletInfo in interface javax.servlet.Servlet

Overrides:

getServletInfo in class javax.servlet.GenericServlet
