[Opensource] Expresso Tags

[Malcolm Wise]

Nelio,

Take a look at

http://www.jcorporate.com/econtent/Content.do?state=template&template=2&reso
urce=636&db=default

scroll down to the Community Contributed Documents.  There is a document
called 'Extended Struts Tags Usage with Expresso'  which may help.

The custom tags you see are Struts 1.0.2 tags
http://jakarta.sun.com/struts/

Expresso has two version of these tags. There are subtle differences

1) Pure 1.0.2 Struts tags

2) Expresso enhanced Struts tags which know about controller elements,
input, outputs, and blocks.

To use either one you specify the TAG LIB DESCRIPTOR (TLD) and
the NAMESPACE in a JSP
e.g

<%@ taglib uri="/WEB-INF/tld/struts-html.tld" prefix="purehtml" %>
<%@ taglib uri="/WEB-INF/tld/struts-bean.tld" prefix="purebean" %>
<%@ taglib uri="/WEB-INF/tld/struts-logic.tld" prefix="purelogic" %>


<%@ taglib uri="/WEB-INF/tld/expresso-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/tld/expresso-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/tld/expresso-logic.tld" prefix="logic" %>
