The Quintessential Servlet</h3>
This example implements a servlet that handles GET requests.
<pre>
package com.mycompany;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class <font color="#0066ff"><i>MyServlet</i></font> extends HttpServlet {
// This method is called by the servlet container just before this servlet
// is put into service. Note that it is possible that more than one
// instance of this servlet can be created in the same VM.
public void init() throws ServletException {
// Initialization code...
// See <a href="../javax.servlet/GetInit.html" class="eglink"><font size="-1"><b>e1035</b> Getting and Setting Initialization Parameters for a Servlet</font></a>
}
// This method is called by the servlet container to process a GET request.
// There may be many threads calling this method simultaneously.
public void doGet(HttpServletRequest req, HttpServletResponse resp) throws IOException {
PrintWriter out = resp.getWriter();
out.println("<html><head><title>A Simple Servlet</title></head><body>");
out.println("Today is "+(new java.util.Date()));
out.println("</body></html>");
out.close();
}
// This method is called by the servlet container just after this servlet
// is removed from service.
public void destroy() {
// Shutdown code...
}
