But when i use:
<xtags:variable id="menu" select="<xpath expression>"/>
and try to do a simple:
<%
System.out.println(menu);
%>
it gives me an error like:
Undefined variable: menu
It's strange...!?

Right - if <xtags:variable> has an 'id' attribute, then you may simply use
it to expose a scripting variable. There isn't a need for <jsp:useBean>
if the tag directly exposes a scripting variable. (So that's your
answer!)
