Using XML in a Servlet
Now let's take the previous example and incorporate it into a servlet. The only difference is
that the XML file that you are parsing has been hard coded into the servlet; therefore, you will
need to replace the <SERVER_ROOT> with the location of your installed Tomcat server. The bet-
ter route would be to use an init parameter, but I want to keep the example as simple as possi-
ble. Listing 10.4 contains our servlet example.

L ISTING 10.4 XMLServlet.java

import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;

import java.util.Hashtable;
import org.w3c.dom.*;
import org.xml.sax.*;
import javax.xml.parsers.*;
import SAXHandler;

public class XMLServlet extends HttpServlet {

private static final String CONTENT_TYPE = “text/html”;

private String moviefile = “<SERVER_ROOT>\\djs\\item.xml”;

public void init(ServletConfig config)
throws ServletException {

super.init(config);

}

public void doGet(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {

doPost(request, response);
