java - Servlet无法正常工作，页面也无法进入tomcat webapps目录

我已经使用Eclipse Luna IDE和一个简单的jsp页面创建了一个简单的servlet。当我部署它时，它不起作用。我正在使用tomcat 8。

错误是

HTTP状态404-/ ServletLearning / DynamicPage / welcome
类型：状态报告

消息：/ ServletLearning / DynamicPage / welcome

描述：请求的资源不可用。

我的代码在这里。

 package atulrai;

 import java.io.IOException;
 import java.io.PrintWriter;

 import javax.servlet.ServletException;
  import javax.servlet.annotation.WebServlet;
 import javax.servlet.http.HttpServlet;
 import javax.servlet.http.HttpServletRequest;
  import javax.servlet.http.HttpServletResponse;

/**
* Servlet implementation class DynamicServlet
*/
 @WebServlet("/DynamicServlet")
public class DynamicServlet extends HttpServlet {
/**
 *
 */
private static final long serialVersionUID = 1L;

public void doGet(HttpServletRequest req, HttpServletResponse res)
        throws ServletException, IOException {


    res.setContentType("text/html");
    PrintWriter pw = res.getWriter();
    String name = req.getParameter("name");
    pw.println("Welcome " + name);
}
}

Jsp页面是

 <html>
<head>
<meta charset="ISO-8859-1">
 <title>dynamic page using Servlet</title>
 </head>
 <body>
<form action="welcome" method="get">
    Enter your name:<input type="text" name="name"><br>
    <input type="submit" value="login">
</form>

</body>
</html>

web.xml

  <?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"

<welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
</welcome-file-list>

<servlet>
    <servlet-name>atulrai</servlet-name>
    <servlet-class>DynamicServlet</servlet-class>
</servlet>

<servlet-mapping>
    <servlet-name>atulrai</servlet-name>
    <url-pattern>/welcome</url-pattern>
</servlet-mapping>

最佳答案

尝试/ ServletLearning / welcome或将index.jsp文件放入WEB-INF。
