Good book/tutorial on EJB Remote Access ?

[effco]

Hello,

I'm currently developping a rich client app that needs to access EJBs remotely.
After looking for docs, I've found only few things:
http://wiki.jboss.org/wiki/Wiki.jsp?page=AccessEJBsRemotely
http://www.javareference.com/books/freebooks/TIE/TIEJv1.1.htm#_Toc39473015

Could you point me to some books to cover this topic in more depth?
I've been looking on Amazon but didn't know really what to buy.

Thanks,

Fred
