Here's the Hello.java code:
/**
* This is a simple example of an HTTP Servlet. It responds to the GET
* and HEAD methods of the HTTP protocol.
*/
public class Hello extends HttpServlet
{
/**
* Handle the GET and HEAD methods by building a simple web page.
* HEAD is just like GET, except that the server returns only the
* headers (including content length) not the body we write.
*/
public void doGet (HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException
{
PrintWriter out;
String title = "Test Tomcat Servlets";
// set content type and other response header fields first
response.setContentType("text/html");
// then write the data of the response
out = response.getWriter();
out.println("<HTML><HEAD><TITLE>");
out.println(title);
out.println("</TITLE></HEAD><BODY bgcolor=\"#FFFFFF\">");
out.println("<H1>" + title + "</H1>");
out.println("<H2> Congratulations, Servlets Work!<br>");
out.println("</BODY></HTML>");
out.close();
}
}
Thanks,
