Calling NumberToWords SOAP 1.2 with SAAJ

Takeaways:

SAAJ does supports SOAP 1.1 and SOAP 1.2.
An empty SOAP message can be created very easily: msg = MessageFactory.newInstance().createMessage().
A SOAP HTTP call can be done very easily too: SOAPConnectionFactory.newInstance().createConnection().call(msg,url).
Don't use xml* as the namespace prefix for your SOAP body elements. SAAJ 1.3.4 implementation will not generate the namespace declaration for you.
