Not to rain on your parade, but both these products only let you use
JavaScript as the scripting language in a JSP page instead of Java.
My understanding of what Yan wants to do is let code running in the
browser call an object living on the server, so replacing one server-side
language with another doesn't help him (probably it just adds to the
confusion).
The only way to let code in the browser invoke some object on the server
is by making a new request. One way of doing this is through an applet, as
someone else suggested, but it still requires a new HTTP request, served by
a special servlet (or JSP page), or a remote call to an RMI server, or something
similar. There's no way to assign a client-side JavaScript variable a direct
reference to a server-side Java object, or a server-side JavaScript object
for that matter (if you use Rhino or BSF). Something is always needed to
bridge the two execution environments, And that's true no matter which
language or server-side technology you use (Perl-CGI, ASP, ColdFusion, etc).
