RE: error while running servlet undet tomcat in Linux Red Hat
Howdy,
How many servlet.jar files do you have loaded? ;) You probably have an
extra one somewhere, e.g. in your /WEB-INF/lib. You should remove
those, and only keep the one that comes with tomcat. Moreover, it looks
like your extra servlet.jar file is v2.2 (or maybe older)...
