JAR files required for Portal Application

Hi Experts

I am currently migrating my custom Masthead application from NW 7.0 to NW 7.3. However, when I migrated the PAR into EAR using migration tool from Portal and imported this EAR file into NWDS7.3, the JSP pages in it shows error. Also when this EAR is directly deployed on the NW 7.3 system, it gives Portal Runtime exception.

<%@ page import = "com.sapportals.portal.prt.session.IUserContext" %>

<%@ page import = "com.sapportals.portal.prt.component.*" %>

<%@ page import = "com.sapportals.portal.prt.service.laf.*" %>

<%@ page import = "com.sap.security.api.*" %>

<%@ page import = "com.sapportals.portal.prt.service.license.ILicenseService"%>

<%@ page import = "com.sapportals.admin.wizardframework.util.ILocaleListService"%>

<%@ page import = "com.sapportals.portal.navigation.*" %>

<%@ page import = "com.sapportals.portal.prt.runtime.PortalRuntime" %>

<%@ page import = "com.sapportals.portal.prt.util.StringUtils" %>

<%@ taglib uri="prt:taglib:tlframework" prefix="frm" %>

The errors shown in the JSP page are due to missing JARs. But I am having trouble in locating the required JAR files on the server. Can anybody tell about which all JARs are required and where i can find them??

Also the imported Framework library is not accessible in the application thus there is error "Can not find the tag library descriptor for "prt:taglib:tlframework"".

Can anybody tell me what i am missing here??
