Method Detail

init

public void init()
          throws javax.servlet.ServletException

Overridden to create and initialize the delegate Servlet instances.

Overrides:

init in class javax.servlet.GenericServlet

Throws:

javax.servlet.ServletException

destroy

public void destroy()

Overridden to destroy the delegate Servlet instances.

Specified by:

destroy in interface javax.servlet.Servlet

Overrides:

destroy in class javax.servlet.GenericServlet

doGet

protected void doGet(javax.servlet.http.HttpServletRequest req,
         javax.servlet.http.HttpServletResponse resp)
              throws IOException

Overrides:

doGet in class javax.servlet.http.HttpServlet

Throws:

IOException

doPost

protected void doPost(javax.servlet.http.HttpServletRequest req,
          javax.servlet.http.HttpServletResponse resp)
               throws IOException

A query can be submitted with a POST if a query parameter is provided. Otherwise delegate to the InsertServlet or DeleteServlet as appropriate.

Overrides:

doPost in class javax.servlet.http.HttpServlet

Throws:

IOException

doPut

protected void doPut(javax.servlet.http.HttpServletRequest req,
         javax.servlet.http.HttpServletResponse resp)
              throws IOException

A PUT request always delegates to the UpdateServlet.

Note: The semantics of PUT are "DELETE+INSERT" for the API. PUT is not support for just "INSERT". Use POST instead for that purpose.

Overrides:

doPut in class javax.servlet.http.HttpServlet

Throws:

IOException

doDelete

protected void doDelete(javax.servlet.http.HttpServletRequest req,
            javax.servlet.http.HttpServletResponse resp)
                 throws IOException
