I have developed a simple facelet portlet. Changed the ViewHandler in the faces-config.xml as it is said in the book:

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE faces-config PUBLIC "-//Sun Microsystems, Inc.//DTD JavaServer Faces Config
1.1//EN" "http://java.sun.com/dtd/web-facesconfig_1_1.dtd">
<faces-config xmlns="http://java.sun.com/JSF/Configuration">
 <application>
   <view-handler>
       com.sun.facelets.FaceletPortletViewHandler
   </view-handler>
 </application>
<factory>
    <faces-context-
        factory>com.liferay.util.bridges.jsf.myfaces.MyFacesContextFactoryImpl</faces-
        context-factory>
</factory>
</faces-config>

There are 2 .xhtml pages: template.xhtml

<?xml version="1.0" encoding="UTF-8" ?>
<f:view xmlns="http://www.w3.org/1999/xhtml"
    xmlns:ui="http://java.sun.com/jsf/facelets"

        <h:outputLabel value="label" for="input"/>
        <h:inputText id="input"/>
        JUST TEXT
        <ui:insert name="insertBlock">
            <h:outputText value="defaultText"></h:outputText>
        </ui:inse开发者_运维百科rt>
    </body>

and insertedBlock.xhtml

<?xml version="1.0" encoding="UTF-8" ?>
<ui:composition template="template.xhtml"

    <h:outputText value="Inderted block"/>
    <h:outputLabel value="test label" for="testInput"/>
    <h:inputText id="testInput"/>
  </ui:define>

</ui:composition>

portlet.xml:

When I deploy this portlet on the Liferay - no errors are displayed. But when I add the portlet on a page IT IS EMPTY - just the empty rectangle. The code of the page (html code inspection in the fireBug) shown that there is no content in the portlet either.

What did I do wrong?

Did you include liferay specific artifacts? For a porlet to be deployed in liferay, the artifact needs some liferay specific configuration files. You can create a skeletal artifact using the Liferay Plugin SDK. (You can find it in, additional files download section.)

Or you can download the JSF samples and alter it to match your configuration.
