1.Tomcat下的Servlet测试

我在Tomcat的webapps建了个eshop的web应用：
webapps
--eshop
----index.jsp
----WEB-INF
------web.xml
--------classes
----------shopping
------------shoppingServlet.class
web.xml的内容是：
<?xml version="1.0" encoding="ISO-8859-1"?>

<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">

<web-app>
<display-name>My Web Application</display-name>
<description>
A application for test.
</description>

<servlet>
<servlet-name>ShoppingServlet</servlet-name>
<display-name>ShoppingServlet</display-name>
<description>A test Servlet</description>
<servlet-class>shopping.ShoppingServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>ShoppingServlet</servlet-name>
<url-pattern>/ShoppingServlet</url-pattern>
</servlet-mapping>

</web-app>

然后我在浏览器里面输入：http://127.0.0.1:8080/eshop/ShoppingServlet
这个servlet是能正确显示的。

而后我把整个eshop目录剪切到webapps\examples下面，重启Tomcat。
在浏览器里面输入http://127.0.0.1:8080/examples/eshop/ShoppingServlet
说找不到这个servlet。

不知道什么原因？

http://127.0.0.1:8080/examples/eshop/ShoppingServlet
Tomcat收到这个请求，会去交给examples这个app来处理
在examples/WEB-INF/web.xml中并没有对ShoppingServlet做servlet-mapping
所以不能处理这个请求

解决方法: 把ShoppingServlet的class或jar文件放到examples/WEB-INF下的classes目录或lib目录
修改examples/WEB-INF/web.xml
添加ShoppingServlet的声明和映射(/eshop/ShoppingServelt)

修改examples/WEB-INF/web.xml
添加ShoppingServlet的声明和映射(/eshop/ShoppingServelt)
在哪一行加都可以吗
