StringUtils cannot be resolved

I am using Java Server Pages and for using the String manipulations and I am using stringutils which I am not able compile. It says that "StringUtils cannot is resolved." I am sorry to say which I added this to CLASSPATH, I had also put the jar file in the Lib file of Apache Tomcat ... and in The lib file where my jsp files are located ...

Actually I am using Dreamweaver Trial version and programmers Notepad ...?

If I want to add a big import: Please tell me how to does so. Or do I had to compile the whole thing?

Looks like the problem are not with the classpath but the import.

Can you import the stringutils in your JSP? Below should help

<%@ page import="org.apache.commons.lang3.StringUtils" %>

I dont see it as classpath issue, because if it is not able to locate the classes, it should has given you classnotfound Exception. But yes, you need to has classpath set properly, which I think you has already taken care of.
