I'm migrating a SAP B2B Commerce project from version 7.0 to 7.4, with the previous version of java 1.4 to 1.7.
Right now I have no java errors, but this error messages in the JSP file:
//the import sap api couldn't not be resolved
<%@ page import="com.sap.isa.core.util.WebUtil" %>
<%@ page import="java.util.Iterator" %>
<%@ page import="java.math.BigDecimal" %>
//Can not find the tag library descriptor for "/isa"
<%@ taglib uri="/isa" prefix="isa" %>
I have been checking the web.xml files and turns out that there are references to a few *.tld
files that are missing, those files describe groups of custom tags with their name, implementation class, body content, attributes and variables.
I think that could be the problem but I'm not sure if those files were lost while the project was migrated to the newer version. (Note: I didn't do that migration, I'm just fixing it to make it work again)
Any thoughts on this? I'm quite new to SAP applications and anything related to it.
UPDATE
It looks like a package/component is missing (com.sap.isa), I have read a similar problem in this page, but since I don't have access permissions to download such component I can't try the solution, also I was told that before the migration, they didn't had such component (and the project worked) nor after the migration.
I've never been involved in the development, just in the migration of it, so I don't know many details of the configuration of it.
