Hi Lakshmi, Try putting the Bean Class (UserData) in WEB-INF\classes directory and make sure it is in the classpath. Also, if you are using 'Tomcat 5', the bean class has to be inside a package.
You have to import only packages. For example, in JSP, you can no longer have <%@page import="someClass"%>. It has to be inside a package. You can only have <%@page import ="somePckg.someClass" %> Otherwise, it'll give exception "."expected

Hi Lakshmi,
Put the UserData inside a package, say "myPack" and put this inside the /WEB-INF/classes folder. In your JSP pages, import the package itself - <jsp:useBean id="user" class="myPack.UserData" scope="session"/> Please check your JSP page for any errors!! Let me know if you have any problems.
I created mypack package.i modified <jsp:useBean id="user" class="mypack.UserData" scope="session"/> .When iam ruuning on Tomcat server iam getting the following error
description The server encountered an internal error () that prevented it from fulfilling this request.

Hi Lakshmi,
I just tried it out and it seems to be working properly. Maybe you have some problem in classpath. Just check if you have the WEB-INF/classes folder in the correct path. Also this bean file inside WEB-INF/classes/myPack/UserData.class. Check for the correct package name too. I found a link where someone had the same problem. Hope it solves yours too!! http://forums.devshed.com/t44539/s.html Let me know if you have more problems.
