JAXP Factories in JBoss EAP 6/7

Issue

• Should we set these system properties to use our JAXP implementations? 2) set these system properties at startup like so:

-Djavax.xml.parsers.DocumentBuilderFactory=com.example.xml.parsers.DocumentBuilderFactoryImpl
-Djavax.xml.parsers.SAXParserFactory=com.example.xml.parsers.SAXParserFactoryImpl

• Why is the class used from the __redirected package for the JAXP factory implementations?

• Using a different Streaming XML API provider in EAP 6

• Our application in EAP 5 to use the old bea streaming API and we used to set the properties below, but with JBoss EAP 6 there is a clash causing my Web / SOAP application to stop working. What is the best way to continue to use our previous streaming provider and may it Available to my application ?

-Djavax.xml.stream.XMLOutputFactory=com.bea.xml.stream.XMLOutputFactoryBase -Djavax.xml.stream.XMLInputFactory=com.bea.xml.stream.MXParserFactory -Djavax.xml.stream.XMLEventFactory=com.bea.xml.stream.EventFactory

• We were wondering if it is safe to change XML transformers or not? One of our developers wants to swap in a new XML library and we want to verify it is JBoss-safe or not. The library is Saxon-HE-9.4.0.6.jar and it will be deployed as a global module, and enabled via a startup parameter equivalent to the below code, is there any concerns in doing this way from JBoss side?

      System.setProperty("javax.xml.transform.TransformerFactory", "net.sf.saxon.TransformerFactoryImpl");

• Is it safe to change XML transformers by setting system properties ?
