Description
Description:
Test in Designer with Java code, "System.out.println(System.getProperty("javax.xml.transform.TransformerFactory"));". You should be able to see "com.tibco.xml.parsers.xmlfactories.TransformerFactory" in BW5.11, but "null" in BW5.9. That is, in BW5.11, "javax.xml.transform.TransformerFactory" is set with the value "com.tibco.xml.parsers.xmlfactories.TransformerFactory" by default. But BW5.9 does not.

Issue/Introduction
Error: "[java.lang.ClassCastException] :
[com.tibco.xml.parsers.xmlfactories.TransformerFactory cannot be cast to
javax.xml.transform.sax.SAXTransformerFactory" while migrating Java activity from BW5.9 to BW5.11.
Resolution
If you need an instance of the "SAXTransformerFactory" class, use setProperty() to specify another compatible
"TransformerFactoryImpl" to override the TIBCO one which has not fully
implemented the SAXTransformerFactory. Example, configure by Java code: System.setProperty("javax.xml.transform.TransformerFactory", "org.apache.xalan.processor.TransformerFactoryImpl");
java.property.javax.xml.parsers.DocumentBuilderFactory org.apache.xerces.jaxp.DocumentBuilderFactoryImpl
}
TIBCO only relies on SAXParserFactory more than SAXTransformerFactory because in both designer.tra files of BW5.9 and BW5.11, at the end of the file you will see
{
java.property.javax.xml.parsers.SAXParserFactory org.apache.xerces.jaxp.SAXParserFactoryImpljava.property.javax.xml.parsers.DocumentBuilderFactory org.apache.xerces.jaxp.DocumentBuilderFactoryImpl
}
