部署时提示的错误信息如下：
Deployment failure on Tomcat 6.x. Could not copy all resources to
E:\apache-tomcat-6.0.16\webapps\HebbnWebServices. If a file is locked,
you can wait until the lock times out to redeploy, or stop the server
and redeploy, or manually remove the deployment at
E:\apache-tomcat-6.0.16\webapps\HebbnWebServices
再次点部署按钮时就会提示如下：
Undeployment Failure could not be redeployed because it could not be
completely removed in the undeployment phase. the most common cuase of
this problem is attempting to redeploy while the server is running,which
has locked one or more files.
to correct the deployment you will need to stop the server and then redeploy the project before restarting the server.
办法就是在Eclipse中把项目中引用的jar文件重新加一遍就行了，基本原因就是以前的jar文件不存在了，但是项目信息中还有，即项目的.classpath文件中还有不存在的jar文件引用。
对照.classpath文件中的classpathentry属性引用的.jar文件和项目lib文件夹中的.jar文件，删除存在于.classpath文件中却不存在于lib文件夹中的节点。
可以右键点项目名称，选择Properties,选择Java Build Path,选择Libraries,把所有项目中的jar都remove，然后再点"add jars"，把项目中的jar文件都加进来，再次部署就正常了。
以前没遇过这个问题，折腾了好久...
