产生问题是因为创建新的server和WEB项目后没有正确配置server服务，现正确配置如下
解决办法：
1.在servers中新建的SERVER上右击——属性的General项下右边Location属性点击SwitchLocation按钮，设置成/Servers/Tomcat v6.0 Serverat localhost.server
(Servers : Properties -> General -> Location =/Servers/Tomcat v6.0 Serverat localhost.server;)
2.双击新建的server，修改Server Options设置：将Publish module contexts toseparate XML files打钩（最下面）
3. 配置WEB项目的server选项：右击WEB项目——属性（properties）——server(新建WEB项目后默认是none)选中里面您servers热部署中创建的server（我的是Tomcat v6.0 Serverat localhost.server）。
搜索到的相关解释：
(
Explaination:
[*]Tomcat of previous version doesn't support the "source" attribute in the "Context" node of "server.xml" file.
Result:
[*]Aseparate XML file named "demo.xml" was created in the "$serverpath$\conf\Catalina\localhost\".
)
注意：【metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\t does not exist or is not a readable directory】该问题是WEB项目作了不恰当的重命名相关文件夹，或则误删除某些目录又重新创建后导致eclipse无法在使用热部署时候自动同步相关配置。
此时：可手动部署方式将固定的WEB部署目录结构创建到metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\目录底下。如：mytest项目 可以创建结构如下：创建mytest目录，在mytest文件夹目录中创建META-INF、WEB-INF两个文件夹目录。配置到这，此两个文件夹目录底下应该放些什么内容，大家应该都清楚了。正常项目tomcat中结构。如果是新建项目啥都还没写的话建议删除重新创建一个WEB项目，此时ECLIPSE会自动感应。
到此配置完毕，重新启动吧。应该没问题了。
