What Tomcat version?
What is a "library"?
Where are you putting your "libraries" if they are in the "correct" place?
What is the URL you are trying to access?
Have you found the useBean declaration that it causing the error(s)?
Can you post that <jsp:useBean>?

You have provided basically no information except that you got an error
message at some point. Provide more details if you wish to get any help.
