我使用tomcat 6在Eclipse中创建了一个servlet应用程序。我将一些信息从表单发送到servlet。我收到错误 - Firefox can't find the file at /C:/workspace-jee/Beer-v1/WebContent/html/SelectBeer.do.如何解决此问题？相关信息如下。如果您需要更多信息，请告诉我。

HTML页面 

<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<h1 align="center">Beer Selection Page</h1>
<form method = "POST" action="SelectBeer.do">

Select beer characteristics<p>
Color:
<select name ="color" size="1">
<option value="light">light</option>
<option value="amber">amber</option>
<option value="brown">brown</option>
<option value="dark">dark</option>
</select>
<br><br>
<center>
<input type = "SUBMIT">
</center>
</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://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
  <display-name>Beer-v1</display-name>
  <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>
    <description></description>
    <display-name>BeerSelect</display-name>
    <servlet-name>BeerSelect</servlet-name>
    <servlet-class>com.example.web.BeerSelect</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>BeerSelect</servlet-name>
    <url-pattern>/SelectBeer.do</url-pattern>
  </servlet-mapping>
</web-app>

Servlet BeerSelect实际存在且代码正确。

Tomcat启动日志 - 我猜他们称之为catalina或其他什么。
