Was successfully able to do it, its pretty simple. Here are the steps :
1. Export the JSF project as WAR, including the source files.
2. Using RAD, create the new faces portlet (in my case 168) project.
3. Now, import the JSF App (.war) into Portlet Project.
4. Changes to be done in the following files
a. faces-config.xml - Add <factory>
<faces-context-factory>com.ibm.faces.context.PortletFacesContextFactoryImpl</faces-context-factory>
</factory>
and
<variable-resolver>com.ibm.faces.application.PortletVariableResolver</variable-resolver>
b. Web.xml - Remove the reference to FacesServlet.
c. Add taglib reference for portlets -
http://java.sun.com/portlet for URL and /WEB-INF/tld/std-portlet.tld for location
d. Portlet.xml - Change the value of init param of �com.ibm.faces.portlet.page.view� to �/xyz.jsp� (entry point of App)
e.
JSP files - add the following the tags and Remove HTML, Body, Head tags
<%@ taglib uri="http://java.sun.com/portlet" prefix="portlet"%>
<portlet

efineObjects />
You are now all set to run the application on portal server.
