ZK - Open Source Ajax Java Framework

I would like to share ZK Framework among multiple projects;
which are the ZK Framework's libraries that I can share in $A(pplication)S(server)_HOME/lib (GLOBAL SCOPE) folder and what do I have to necessarily put into PROJECT/WEB-INF/lib (PROJECT SCOPE) folder each project, to make projects with ZK work properly?

could someone help me?

I use Resin Web Applicatin Server!

thanks to all

Please refer to quick start guide,

Alternative 1: Bundle ZK into Your Web Application
http://www.zkoss.org/doc/quickstart/ch04s01.html
Alternative 2: Install ZK to Be Shared by All Web Applications
http://www.zkoss.org/doc/quickstart/ch04s02.html

But we suggest you put ZK libraries only in project scope. As Tomcat's default.
Note: Tomcat 6.x, by default, doesn't load any classes from the shared/lib directory.

thanks Peter
