Using the portlet:resourceURL UI Component

The Liferay Faces Bridge component suite provides many Portlet 2.0 UIComponent tags that are useful for JSF development. In this tutorial, you’ll learn about the portlet:resourceURL tag.

If the var attribute is present, the portlet:resourceURL tag introduces an EL variable that contains a javax.portlet.ActionURL, adequate for obtaining resources. Otherwise, the URL is written to the response.

<?xml version="1.0" encoding="UTF-8"?>
<f:view xmlns="http://www.w3.org/1999/xhtml"
    xmlns:f="http://java.sun.com/jsf/core"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:portlet="http://java.sun.com/portlet_2_0"
    xmlns:ui="http://java.sun.com/jsf/facelets">
    <h:head />
    <h:body">
        <h:form>
            <portlet:resourceURL var="myResourceURL">
                <portlet:param name="foo" value="1234" />
            </portlet:resourceURL>
            <h:outputText var="actionURL=#{myResourceURL}" />
        </h:form>
    </h:body>
</f:view>
