I need to call some classes in the web-inf / lib / j2ee.jar package in Tomcat5, I will follow the J2EE.jar package COPY to this directory, restart Tomcat, the result program error, did not find the related class , I will solve the problem in the J2EE.jar file Copy to Tomcat / Common / Lib.
I estimate that some Class files in Web-INF / LIB /, such as servlet.jar et al., Are caused by certain Class file conflicts in J2EE.
