ui:composition template=“<template from jar>”

问题

I would like to place the Facelets template file for JSF in a JAR file.

I tried to reference it by EL as

<ui:composition template="#{resource['templates:template_pe_layout.xhtml']}">

which works perfect for CSS or images, but not for the composition template.

How could I achieve the goal?

回答1:

The #{resource} expression is initially designed for use inside CSS files only like so

.someclass {
    background-image: url(#{resource['somelibrary:img/some.png']});
}

It's not intented for usage in <h:outputStylesheet>, <h:outputScript> or <h:graphicImage> which should rather be used as follows:

<h:outputStylesheet library="somelibrary" name="css/some.css" />
<h:outputScript library="somelibrary" name="js/some.js" />
<h:graphicImage library="somelibrary" name="img/some.png" />

As to the templates, just specify the full /META-INF/resources relative path in there.

<ui:composition template="/templates/template_pe_layout.xhtml">
