Question

我创建了一个简单的jsp程序。程序中没有错误。但是当我在eclipse中运行apache tomcat serverv7.0时，它会显示： 404资源不可用。有人可以告诉我为什么会这样吗？我在日食火星上创造了程序。我的代码如下：的index.jsp \

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<form action="process.jsp">  
No1:<input type="text" name="n1" /><br/><br/>  
No1:<input type="text" name="n2" /><br/><br/>  
<input type="submit" value="divide"/>  
</form>

String num1=request.getParameter("n1");  
String num2=request.getParameter("n2");
