Adv Java Program : Write a SERVLET program that provides information about a HTTP request from a client, such as IP address and browser type. The servlet also provides information about the server on which the servlet is running, such as the operating system type, and the names of currently loaded servlets.
serverInfo.java
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class serverInfo extends HttpServlet implements Servlet
{
protected void doGet(HttpServletRequest req,HttpServletResponse res)throws IOException,ServletException
{
res.setContentType("text/html");
PrintWriter pw=res.getWriter();
pw.println("<html><body><h2>Information about Http Request</h2>");
pw.println("<br>Server Name: "+req.getServerName());
pw.println("<br>Server Port: "+req.getServerPort());
pw.println("<br>Ip Address: "+req.getRemoteAddr());
//pw.println("<br>Server Path: "+req.getServerPath()); pw.println("<br>Client Browser: "+req.getHeader("User-Agent"));
pw.println("</body></html>");
pw.close();
}
}
