On which OS did you install tomcat6?

If your OS would be Debian or Ubuntu, /usr/share/tomcat6/lib/ is the
place to make weka.jar available for all webapps on tomcat. After
dropping it in there, did you restart tomcat?

Have you checked the file permissions of weka.jar? It has to be readable
for the user tomcat6 is running with.
