Struts - import com.opensymphony.xwork2.ActionSupport;

I am writing Struts code after 2 years.

As I am trying to write a sample struts code from the website and run the build file it is giving the following error. I have placed The following jar files in the classpath of environment variables
C:\struts-2.0.11.1\lib\xwork-2.0.4;C:\struts-2.0.11.1\lib\struts-core-1.3.5;
C:\struts-2.0.11.1\lib\tiles-core-2.0.4;C:\struts-2.0.11.1\lib\tiles-jsp-2.0.4;
C:\struts-2.0.11.1\lib\struts2-core-2.0.11.1;C:\struts-2.0.11.1\lib\ognl-2.6.11;

My code is located in a different directory
C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\struts2tutorial\WEB-INF\src\java\net

The build statement is not recognising the following import statement

import com.opensymphony.xwork2.ActionSupport;

I am really not aware of this new struts which deals with xworks. Please guide me. The error I got is displayed below.
