在Eclipse中如何修改web.xml文件

[javainthinking]

我在Eclipse中建一个tomcat Project名为Test，然后创建一个Servlet包，建一个Hello world的servlet文件.
然后我想在Test的项目下建一个web.xml文件，
第一个问题：不知道用什么可以建xml文件（菜：^_^）
于是我把tomcat的web.xml文件copy过来，我把其中内容都删除了，添加如下代码就够了吗？
<web-app>
<servlet>
<servlet-name>Helloworld</servlet-name>
<servlet-class>servlet/Helloworld</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Helloworld</servlet-name>
<url-pattern>/Helloworld</url-pattern>
</servlet-mapping>
</web-app>
如果少了，还应该添加什么呢？

<web-app>
<servlet>
<servlet-name>Helloworld</servlet-name>
<servlet-class>servlet/Helloworld</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Helloworld</servlet-name>
<url-pattern>/Helloworld</url-pattern>
</servlet-mapping>
</web-app>
就可以啦,
不过你最好在eclipse里安装xml plugin
有XMLeditorForEclipse2.1,myeclipse等,都很好用的。
