TAglib error in AFP layout customization in Sap portal 7.3

Hi team,

I am doing the customization for AFP layout application.

I have downloaded the application and imported in NWDS there were lots of build error coming which was removed adding the relevant jar files.

But there are still two build error which i am not able to resolve.

1.can not find the tag library  descriptor in "prt:taglib:com.sap.portal.reserved.layout.TagLibLayout"

line of code is for that error

<%@ taglib uri="prt:taglib:com.sap.portal.reserved.layout.TagLibLayout" prefix="lyt" %>

2.epagevariables can not be resolved.

code for that is

LShapeController controller = new LShapeController(req, resp, epPageVariables);

my portalapp.xml code for taglib is

<property name="com.sap.portal.reserved.layout.TagLibLayout" value="/SERVICE/com.sap.portal.pagebuilder/taglib/layout.tld"/>

                <property name="com.sap.portal.reserved.layout.TemplateFile" value="LShapeLayout.jsp"/>

I am using NWDS 7.3 SP08 PAT013.

Thanks
