java.lang.ClassCastException：无法将 Servlet.Telnet 转换为 javax.servlet.Servlet

Question

I want to implement a servlet and call it in a WebApp.

I am constantly get java.lang.ClassCastException: Servlet.Telnet cannot be cast to javax.servlet.Servlet from the Apache Tomcat Server. I made sure my class extends HttpServlet this is my code:

package Servlet;

import java.io.IOException;
import java.io.PrintStream;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.commons.net.telnet.TelnetClient;




public class Servlet extends HttpServlet {


    protected void processRequest(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        response.setContentType("text/html;charset=UTF-8");
        PrintWriter out = response.getWriter();
        try {
             TelnetClient telnet = new TelnetClient();
             telnet.connect(request.getParameter("router"), 23);
             PrintStream output = new PrintStream(telnet.getOutputStream());
             output.println(request.getParameter("login"));
             output.flush();
             output.println(request.getParameter("password"));
             output.flush();
             out.printf("SUCCESS");



             telnet.disconnect();




        } catch (Exception e) {
            e.printStackTrace();
            out.printf("ERROR");

        }
    }

我重命名了包和类，它工作得很好。
