我正在嘗試使用 tomcat 服務器版本 9 運行 java 應用程序。當我創建第一個項目并且項目運行成功但問題是當我創建另一個項目并將該項目分配給服務器時，我收到以下錯誤。服務器 Tomcat v9.0 本地主機上的服務器無法啟動。這是index.html的代碼<!DOCTYPE html><html><body><body><form action="login">User Name:<input type="text" name="userName"/>Password:<input type="password" name="userPassword"/><input type="submit" value="submit"/></form></body></html>這是 Servlet 代碼。package Edureka;import java.io.*;import javax.servlet.annotation.WebServlet;import javax.servlet.http.*;@WebServlet("/login")public class MyServlet1 extends HttpServlet{/** * */ private static final long serialVersionUID = 1L;public void doGet(HttpServletRequest request, HttpServletResponse response) {try{response.setContentType("text/html");PrintWriter pwriter = response.getWriter();String name = request.getParameter("userName");String password = request.getParameter("userPassword");pwriter.print("Hello here:"+name);pwriter.print(" Your Password is: "+password);//Creating two cookiesCookie c1=new Cookie("userName",name);Cookie c2=new Cookie("userPassword",password);//Adding the cookies to response headerresponse.addCookie(c1);response.addCookie(c2);pwriter.print("<a href='welcomehere'>View Details</a>");pwriter.close();}catch(Exception exp){System.out.println(exp);}}}這是 web.xml 文件。<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd" id="WebApp_ID" version="4.0"> <display-name>Cookies</display-name> <servlet><servlet-name>Servlet1</servlet-name><servlet-class>Edureka.MyServlet1</servlet-class></servlet>這是我嘗試在 Eclipse 中運行它時的屏幕截圖。
