Solution: My tomcat in myeclipse9.0 is damaged. I re-installed tomcat. Check the configuration first, and check the jar package (anlr. jarcommons-beanutils.jar commons-digester.jar commons-logging.jar commons-fileupload.jar commons-validator.jar jakarta-oro.jarstruts.jar), not because of packet problems, finally, put the Tomcat Directory: C: \ Program
Files \ Apache Software Foundation \ Tomcat 7.0 \ webapps can be deleted from the original project.
