Solution to start Tomcat Web-inf\lib\j2ee.jar jar not loaded exception

When the project was loaded today, the Tomcat report was suddenly discovered:
2010-7-1 12:11:38 Org.apache.catalina.loader.WebappClassLoader Validatejarfile
Information: Validatejarfile (C:\Program files\apache software foundation\tomcat 6.0\web
Apps\accountant\web-inf\lib\j2ee.jar)-jar not loaded. See Servlet Spec 2.3, SE
Ction 9.7.2. Offending Class:javax/servlet/servlet.class

It says J2ee.jar not loaded, what's going on.
The reason may be multiple loads.

Solution: The project \web-inf\lib under the J2ee.jar package can be removed, because \tomcat\lib may already contain the J2ee.jar (although I did not find, hehe)
The following figure is the package under \tomcat\lib




Other:
If Tomcat reports the following exception (shutdown immediately after the program starts):
