* implementation. This method uses the following ordered lookup procedure to determine the SAAJMetaFactory implementation class to load:
*
* - Use the javax.xml.soap.MetaFactory system property.
* - Use the properties file "lib/jaxm.properties" in the JRE directory. This configuration file is in standard java.util.Properties format and contains the fully qualified name of the implementation class with the key being the system property defined above.
* - Use the Services API (as detailed in the JAR specification), if available, to determine the classname. The Services API will look for a classname in the file META-INF/services/javax.xml.soap.MetaFactory in jars available to the runtime.
* - Default to com.sun.xml.messaging.saaj.soap.SAAJMetaFactoryImpl.
