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: java.lang.IllegalStateException: Response has already been committed at org.apache.tomcat.core.HttpServletResponseFacade.sendError(HttpServletResponseFacade.java:157) at org.apache.jasper.runtime.JspServlet.unknownException(JspServlet.java:299) at org.apache.jasper.runtime.JspServlet.service(Compiled Code) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at org.apache.tomcat.core.ServletWrapper.handleRequest(Compiled Code) at org.apache.tomcat.core.ContextManager.service(ContextManager.java:559) at org.apache.tomcat.service.http.HttpConnectionHandler.processConnection(Compiled Code) at org.apache.tomcat.service.TcpConnectionThread.run(Compiled Code) at java.lang.Thread.run(Compiled Code) ------------------ while on the tomcat console in command prompt the error is: java.lang.NoClassDefFoundError
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.
