Thanks in advance Chaitali
Class files do not go into the JSP directory! Don't forget that files in there can be requested by a client - you don't want everyone downloading your class files, do you? There should be a WEB-INF directory, probably tomcat/webapps/examples/WEB-INF (I don't know Tomcat that well). Class files go into WEB-INF/classes/. Don't forget to turn package names into subdirectories (i.e. com.chaitalid.MyClass would go into WEB-INF/classes/com/chaitalid/). Should you want to package your classes up in a jar file, the jar would go into WEB-INF/lib/. - Peter

"chaitalid", The Java Ranch has thousands of visitors every week, many with surprisingly similar names. To avoid confusion we have a naming convention, described at http://www.javaranch.com/name.jsp . We require names to have at least two words, separated by a space, and strongly recommend that you use your full real name. Please log in with a new name which meets the requirements. Thanks.
First of all , you must place your class files in the class path of your server. Then the server will always load your custom class and make it available for use in your jsp. also if you are using package(looks like you kave your class in a package names counter), then you must instantiate the bean using <jsp:useBean id="counter" scope="session" class="counter.Counter" />
