I've not looked at this for a while but on the discussion forum on the books
web site they've spoken about how the .tld is incorrect in the book and how
you need to make some changes to get mutlib working.
Looks like I've got it working so I'll compare what I have to what you have.
The DTD for tlds says that the order has to be different from what they
supplied
in the box. Look at bodycontent, info, attribute and compare the ordering
with
what yours has.
Also this is my HTML file.
The url is mut and the prefix is mut no mutlib as per the book. The authors
really should have gotten around to updating these changes in the online
source code.. because the books an excellent one.
<%@ taglib prefix="mut" uri="/mut" %>
