JSP error in crm/isa/web/b2b from SC SAP-SHRWEB

Hi All,

I am new to e-commerce application and implementing b2b, e-commerce (version 7.3),  R3 edition. In order to do some enhancements in the standard code we have installed NWDI server.  I have created a project from DC, crm/isa/web/b2b  which is taken from SC, SAP-SHRWEB[sap.com].   After downloading the project (DC) on local, we are encountering some reference issues in all JSP files as below

<%@ taglib uri="/isa" prefix="isa" %>

<%@ taglib uri="/isacore" prefix="isacore" %>

Cannot find the tag library descriptor for u201C/isau201D

Cannot find the tag library descriptor for u201C/isacoreu201D

<%@ page import="com.sap.isa.core.util.WebUtil" %>

<%@ page import="com.sap.isa.catalog.webcatalog.WebCatItem" %>

The import com.sap cannot be resolved.

What could be the issue? Please help. Thanks in advance.

Regards

Rahul
