Myeclipse下的Tomcat映射问题

　　这个问题真的很头疼啊。

环境是：

Myeclipse2015

tomcat 8(使用Myeclipse默认导入的配置)

问题呢：

　　在Myeclipse下创建一个web project，如果是不创建默认web.xml，就可以进入index页面。

　　如果默认创建了web.xml文件，就会出现404错误。

　　然而，最头疼的是，我创建了一个EasyUI的测试project，页面就两个，index.jsp和main.jsp，

 1 <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
 2 <%
 3 String path = request.getContextPath();
 4 String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
 5 %>
 6 <!DOCTYPE html>
 7 <html>
 8   <head>
 9       <meta charset="UTF-8">
10     <title>Basic Combo - jQuery EasyUI Demo</title>
11     <link rel="stylesheet" type="text/css" href="/lib/themes/default/easyui.css">
12     <link rel="stylesheet" type="text/css" href="lib/themes/icon.css">
13     <script type="text/javascript" src="/lib/jquery.min.js"></script>
14     <script type="text/javascript" src="/lib/jquery.easyui.min.js"></script>
15   </head>
16   <body class="easyui-layout">
17     <div data-options="region:'north',title:'North Title',split:true" style="height:100px;"></div>
18     <div data-options="region:'south',title:'South Title',split:true" style="height:100px;"></div>
19     <div data-options="region:'east',title:'East',split:true" style="width:100px;"></div>
20     <div data-options="region:'west',title:'West',split:true" style="width:100px;"></div>
21     <div data-options="region:'center',title:'center title'" style="padding:5px;background:#eee;"></div>
22    </body>
23 </html>

　　在Myeclipse编辑器的模式下，没有任何报错，js文件引用也是没有问题。

　　然后，在导入到Tomcat下运行时，问题来了，提示easyui.css、icon.css、jquery.min.js、jquery.easyui.min.js 404错误

　　看错误下的地址是http://localhost:8080/lib/themes/default/easyui.css

　　如果是正确的路径的话，lib目录在 %Tomcat_Path%/webapps/webte/lib/themes/default/easyui.css

　　暂时的解决办法就是在%Tomcat_Path%/webapps/下，把lib文件夹复制一份到这里，然后，页面就显示正常了

　　问题探究，在Myeclipse下，启动tomcat，在Console下也灭有提示明显的错误，也没有修改过Myeclipse的配置，然而，就是不能用。感觉一下子没了头绪
