Summary

Rule-Utility-function(RUF) getXpathNode is behaving differently after upgrading to Pega 7.2.2.

User has a data page Declare_Products in the environment which is not getting loaded because of the upgrade. This is working fine in another environment which is on Pega 7.2.

Error Messages

Not applicable

Steps to Reproduce

1) Log into Application.
2) Run the data page that uses the RUF.

Root Cause

The classes that are being referred in this function getXPathNode are coming from ‘net.sf.saxon.xpath.*’, whereas the same classes are coming from ‘com.sun.org.apache.xpath.*’ in another environment which is on Pega 7.2 in which there is no issue.

Resolution

Change the RUF code to fetch XPathFactory.newInstance(); as new XPathFactoryImpl() and import package "com.sun.org.apache.xpath.internal.jaxp.XPathFactoryImpl" in Imports & Exceptions tab of the RUF. 

This will make to use the implementation of ""com.sun.org.apache.xpath.internal.jaxp.XPathFactoryImpl" instead of "net.sf.saxon.xpath.XPathFactoryImpl".
