Wow, that is real gibberish. "Installed in the JVM" takes the cake
If you are going to use ANY additional libraries in a Tomcat installation you have to pay attention to how Tomcat locates classes. A typical tomcat installation usually includes a file "class-loader-howto.html" under webapps/docs that will fill you in.
NOTE: You will also have to make sure that your compile environment can find the libraries - this is a separate problem.
