How to create a JSF Portlet using MyFaces:

Make sure your JSF MyFaces application runs as a stand-alone servlet.
Remove any redirects from your faces-config.xml. Portlets can not handle these.
Create a Portlet WAR as per the instructions for your Portlet container. Make sure it contains everything that was included in step 1.
Update your portlet.xml file as follows:


                <!-- You must use this Portlet impl class -->
                <portlet-class>org.apache.myfaces.portlet.MyFacesGenericPortlet</portlet-class>

                <!-- The "home page" of your JSF application -->
                <!-- This is a required param.               -->
                <init-param>
                <name>default-view</name>
                <value>/some_view_id_from_faces-config</value>
                </init-param>

                <!-- A class name that implements org.apache.myfaces.portlet.DefaultViewSelector -->
                <!-- This optional param is used if your want to choose different default views  -->
                <!-- based on some condition.  You still must specify default-view above, but    -->
                <!-- this impl will take precedence.                                             -->
                <init-param>
                <name>default-view-selector</name>
                <value>com.foo.MyViewSelector</value>
                </init-param>
