Question

<form action="../SelectBeer.do" method="POST">
    <p>Select Beer Characteristics</p>
    <p>Color</p>
    <select name="color" size="1">
        <option>light</option>
        <option>amber</option>
        <option>brown</option>
        <option>dark</option>
    </select>
    <br><br>
    <center>
    <input type="submit">
    </center>
</form>

以下是我的form.html的代码，其路径是/Library/Tomcat/webapps/Project/form.html

package com.example.web;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
@WebServlet("/SelectBeer.do")
class BeerSelect extends HttpServlet
{   

public void doPost(HttpServletRequest request,HttpServletResponse reponse) throws ServletException,IOException
{   
    reponse.setContentType("text/html");
    PrintWriter out=reponse.getWriter();
    out.println("Beer Selection Advice<br>");
    String c=request.getParameter("color");
    out.println("<br>Got Beer Color "+ c);
}
}

这是我的BeerSelect.java文件，其路径为/Users/MyName/Desktop/ServletProjects/BeerAdvisor/src/com/example/web/BeerSelect.java

</servlet>
<servlet-mapping>
    <servlet-name>Beer</servlet-name>
    <url-pattern>/SelectBeer.do</url-pattern>
</servlet-mapping>

当我提交表单时，页面显示Error404 Not Found，原始服务器没有找到目标资源的当前表示，或者不愿意透露存在该表示。可以请某人帮忙。

未找到错误404
