My project is using multiple implementations of XML processors (Java default, saxon 9, xerces 2). So, for x开发者_开发技巧ml processing I have to tell which class to load for DocumentBuilderFactory and XPathFactory etc.

We can do it in several ways as defined in Java docs. What is good practice for this:

Use Constructor as introduced in Java 6 (Project already has dependency on Java 6)?
Use the javax.xml.parsers.DocumentBuilderFactory/XPathFactory system properties?
Use the properties file "lib/jaxp.properties" in the JRE directory?
Use the Services API?

I'd go with option 1 as it's the least "magic". As an aside, last I checked the "Java default" XML parser was just a broken version of xerces.
