I can use
< Context path="/images" docBase="I:/images" >
to share a unique images folder between different web applications.

But if I try to share html files or jsp files, it doesn't run
E.g.
< Context path="/commonhtml" docBase="I:/commonhtml" >
and in a JSP, I try to use
< jsp : include page="/commonhtml/header_marco.html" flush="true" / >


does anybody knows how to include jsp or htmls with a path based on web server?
