tomcat中无法部署myeclipse中的项目问题

具体问题:

 

Deployment failure on Tomcat 5.x. Could not copy all resources to C:/Program Files/Apache Software Foundation/Tomcat 5.5/webapps/dataExchange. 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 C:/Program Files/Apache Software Foundation/Tomcat 5.5/webapps/dataExchange

 

解决方法：

       工程中引用的包找不到,重新导入jar包
