Servlets and XML: Made for Each Other

A very basic servlet

For our first example, the middle step of creating the XML document is not our concern; we simply want to generate a valid XML document. We've hardcoded the document into our source code, shown in Listing 1.

Listing 1. xmlfromscratch.java



publicclassxmlfromscratchextendsHttpServlet 

{

  publicvoidservice(HttpServletRequestrequest,

                      HttpServletResponseresponse)

    throwsIOException, ServletException

  {

    response.setContentType("text/xml");

    PrintWriterout = response.getWriter();

    

    out.println("");

    out.println("");

    out.println("  Hello, World!");

    out.println("");

  }

}

The result generated by this exciting piece of code looks like this:

Listing 2. Results from xmlfromscratch.java





  Hello, World!
