I remebered originally my file structure was as follows: webapps\isotrackingtest
isotrackingtest\isotracking isotrackingtest\META-INF isotrackingtest\WEB-INF isotrackingtest\index.jsp isotracking\isotracking isotracking\index.jsp isotracking\isotracking\*.jsp and *.html META-INF\context.xml WEB-INF\classes\isotrakcing\SessionBean.class WEB-INF\lib\sqljdbc.jar WEB-INF\src\isotracking\SessionBean.java WEB-INF\web.xml I moved META-INF and WEB-INF from isotrackingtest\META-INF and isotrackingtest\WEB-INF to isotrakcingtest\isotrakcing\. Then "the value for the useBean class attribute isotracking.SessionBean is invalid" comes up. I put back META-INF and WEB-INF file in isotrackingtest directory and now the error has disappeared. I can see main page but Java Bean call <%= sessionBean.getFname() sessioBean.getLname() %> doesn't display the names on the browser. I can see the function are working fine on the Tomcat console... and I have a valid bean class declared as public and has a public default constructor with no argument. Is this something to do with a library missing? I'm frustrated ... ANY HELP IS HELHLY APPRECIATED! Thanks a lot!

Seems like if that was the case there would be some kind of exception in the logs when the webapp started though. The link I posted below actually came from near the top of a google search on "the value for the useBean class attribute is invalid". You could also try looking through those search results for possibilities. --David Aynalem, Seblewengel (Trawick) wrote: >SessionBean is declared public and it has a public default constructor with no >agrument... but still shows "the value for the useBean class attribute >ISOTracking.SessionBean is invalid" error. > >What could be wrong?
