Modify AJAX Framework Page Layout - Needed JAR files !!

I am trying to add a footer to the the layout of Ajax Framework Page. I imported the war file of com.sap.portal.navigation.afp.layout. After importing, I am not able to resolve the following errors in the editor. I added most of the JARs, but cant seem to resolve the followings,

LShapeLayout.jsp

1) <%@ taglib uri="prt:taglib:com.sap.portal.reserved.layout.TagLibLayout" prefix="lyt" %>
2) IDocModeService - <%@ page import="com.sapportals.portal.prt.service.laf.IDocModeService" %>
3) IDocModeService docModeService = (IDocModeService) PortalRuntime.getRuntimeResources().getService(IDocModeService.KEY);

afpFrameworkLayout.jsp

1) <%@ page import="com.sap.portal.navigation.json.JSONArray" %>
2) epPageVariables
3) JSONArray

How do I resolve these? What are the JAR files?

Thanks

Sandip
