Why can't Tomcat find the JARs?
Thanks in advance,

So you keep your 3rd party JARs located in the directory /MyWebApp/lib
inside your project and would like them copied to /WEB-INF/lib/ at
deployment.
Check out the J2EE Module Dependancies project properties page for
button Add External JARs.
However I'm not sure if this feature is 100% working in 1.0RC1 or even
if it will be 100% working by 1.0 final, for this to happen both server
publication and export to WAR need to be able to deal with this new
feature correctly.
Until then your only other option is to copy the files into
WebContent/WEB-INF/lib directory and refresh your project.
