i have placed the class file in the WEB-INF/classes in the project directory and the when i run my aplication this is what comes...

I have experienced a similar problem and I guess its a problem of the class loader which is responsible for the web application (I am not sure if it is a bug). By adding the bean to import clause, all worked fine for me. Try adding this to your JSP page:

<%@ page import="TechSupportBean" %>
