1. If you are using precompiled jsp or tag files, you should compile
them with exact the same x.y.z version of Tomcat where you deploy
them.

2. Stop Tomcat and clear everything from the /work subdirectory of
CATALINA_BASE. That is, there might be *.class files compiled with
some other version of Tomcat.

Best regards,
Konstantin Kolinko
