problem in using beans in tomcat

The problem seems to be very frequent among tomcat users, as there are a lot of similar questions on web. well the problem is that the tomcat can't find the classes though i put them in webapps/ROOT/myapps/WEB-INF/classes folder. if i put them in shared folder then it can find them.
i don't know what to do with this.

thanassis

change
webapps/ROOT/myapps/WEB-INF/classes
with
webapps/myapps/WEB-INF/classes

thanassis

and then restart tomcat
