Creates a new SOAPFactory object that is an instance of the default implementation (SOAP 1.1), This method uses the following ordered lookup procedure to determine the SOAPFactory implementation class to load:

Use the javax.xml.soap.SOAPFactory 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.SOAPFactory in jars available to the runtime.
Use the SAAJMetaFactory instance to locate the SOAPFactory implementation class.

Returns: a new instance of a SOAPFactory

Exceptions:

SOAPException if there was an error creating the default SOAPFactory
