* <UL>
|

* <LI> Use the javax.xml.soap.MetaFactory system property.
|
|
* <LI> 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.
|
|
* <LI> 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.
|
|
* <LI> Default to com.sun.xml.internal.messaging.saaj.soap.SAAJMetaFactoryImpl.
