Custom JSF tags

paulo.dangelo Jan 5, 2007 7:49 AM

Help .... I´m trying to add custom JSF tags on an Seam application but Jboss keeps ignoring then.

I´ve created div, ul and li tags (as described on the posts http://www.it-eye.nl/weblog/2006/04/25/creating-a-jsf-div-component/ and http://thepeninsulasedge.com/blog/2006/08/28/jsf-html-div-and-ul-tags/) and added the requested entries to faces-config.xml and to a new \WEB-INF\taglib.tld file as described on the Configuration part of the post.

The problem is that Jboss Seam seams to be ignoring the new custom tag:

Example.xhtml:

<div class="menuButtons"
xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:s="http://jboss.com/products/seam/taglib"
xmlns:hg="http://www.xxxxx.com/jsf">

<hg:div id="mainnav" styleclass="nav" rendered="#{loggedIn!=null}">

....

Processed page:

<div class="menuButtons" xmlns="http://www.w3.org/1999/xhtml" xmlns:hg="http://www.griffo.com.br/jsf">

<hg:div id="mainnav" styleclass="nav" rendered="false">

?.

Not even the xmlns entry is processed. Please, anyone have a clue?

Looks to me like you are using facelets. In that case you need to wire your custom components as for facelets not JSP. Take a look at the facelets documentation which explains how to do this.

You need to check the facelets documentation to see how to declare facelets taglibs. It doesn't use a tld file.

Here's a facelet tag example:

Nice .. Thanks for all the replies ?.

I saw the facelet tag example but have one doubt: How do I represent a div html tag similar to the nbsp showed there? Would it be something like this?

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:ui="http://java.sun.com/jsf/facelets">

<ui:composition>
<f:verbatim>??? What goes here? ???</f:verbatim>
</ui:composition>

ok ... problem solved. No need for a xhtml file.

I keep all code as initially described in the first post but, instead of using the tld descriptor, I use the xml one as this:

<?xml version="1.0"?>
<!DOCTYPE facelet-taglib PUBLIC
"-//Sun Microsystems, Inc.//DTD Facelet Taglib 1.0//EN"
"facelet-taglib_1_0.dtd">

<facelet-taglib>
http://www.xxxxx.com/jsf

<tag-name>div</tag-name>

<component-type>javax.faces.Panel</component-type>
<renderer-type>com.xxxxx.framework.view.jsf.components.Div</renderer-type>

</facelet-taglib>

and the reference on web.xml:

<context-param>
<param-name>facelets.LIBRARIES</param-name>
<param-value>
/WEB-INF/xxxxx.taglib.xml
</param-value>
</context-param>

Thank you all for your help.

Paulo.
