I did not quiet understand your problem, but here is some
information that you may use:
In the
tomcat server, when you develop your classes and you want to make them available to the web application , you have 2 coices.
1:- to make these classes available to a certain web application.
if you wanna do so , place the classes packed on classes directory under the web-inf directorey of your web application , or put them on a Jar file and place it on the lib directory under the web-inf directory of your web application.
2:- To make the classes available to all of the web applications deployed on the tomcat server , place them packed under $CATALINA_HOME/classes, or put them on a jar file and place them on $CATALINA_HOME/lib.
You don't have to define any class path for the tomcat , because it has it's own ones.
bye.
