我有一个带有Spring mvc的简单J2ee应用程序。 因此，当我尝试运行服务器Tomcat 7.0时，我遇到此错误，但应用程序正常运行。
The error is:
Grave: Error starting static Resources
java.lang.IllegalArgumentException: Document base C:\Users\michele.castriotta\Dropbox\workspace_j2ee\.metadata\.plugins\org.eclipse.wst.server.core\tmp1\wtpwebapps\SpringMVC does not exist or is not a readable directory
