Thanks to Raghav and Jason,I still have the problem,here is the error message when the link to JSP page is clicked in browser:
---------------
Error: 500
Location: /examples/jsp/lbm/registerJSP.jsp
Internal Servlet Error:

I think you might have two problems here.
The NoClass error, seems to point that either your JSP references a bean whose class is not in the web-inf/classes folder.
The response is already committed error occurs frequently if
you have <jsp:include page in your linked JSP, you cannt set headers, redirect or forward if you have used <jsp:include becuase the flush attribute must be set to "true"
if you can replace <jsp:include with <%@ include instead it will fix that problem

Thank you, Glenn
I checked my code, I did use <%@ includ rather than <jsp:include.After I put my program on the remote tomcat server, it works well(I got the error message on local server).I can't explain it, but anyway,it works.
Thank you for your help.
