Re: How can I avoid using the jsp:useBean tag?

[Bruno Aranda <br...@gmail.com>]

Maybe you could create a list with your properties (invoking your
setup method before adding the property to the list), and the usint a
dataTable or dataList to show the properties... This should work and
is more elegant ;-)
