[Re: soap messaging XML ???]

[Iain Potter <ip...@prismtechnologies.com>]

Hi,

Have you looked at Sun's JAXM specification? Basically, it's a 
standardised SOAP API for Java.

We're currently developing an implementation of the JAXM Version 1.0 
specification which should be available soon. We allow SOAP messages to 
be transported over HTTP or JMS.

JAXM uses MessageFactory objects to produce SOAPMessage instances, which 
you then populate with your message content. If you're sending via HTTP, 
you'll generally use a SOAPConnection object to do this. Anyway, here's 
an example of how you could use JAXM to produce the same message and 
send to an endpoint via HTTP:-

----------
SOAPConnectionFactory connectionFactory = 
SOAPConnectionFactory.newInstance();
SOAPConnection connection = connectionFactory.createConnection();
MessageFactory factory = MessageFactory.newInstance();

SOAPMessage message = factory.createMessage();
SOAPPart soapPart = message.getSOAPPart();
SOAPEnvelope envelope = soapPart.getEnvelope();
SOAPBody body = envelope.getBody();

Name name = envelope.createName("methodToCall", "ns1", 
"uri:MySoapObjectToCall");
SOAPBodyElement element = body.addBodyElement(name);

URLEndpoint endpoint = new URLEndpoint(some_url);
SOAPMessage reply = connection.call(message, endpoint);
-------------

Obviously, you will only receive a reply from the connection.send() call 
if one is actually sent back!

What is also quite nice is that it's very easy to create SOAPMessage 
instances from an XML file. All you need to do is create an InputStream 
containing the file content, and set the "Content-Type" MIME header for 
the message (you can also set other MIME headers if you wish). So, the 
code would be:-

-------------
SOAPConnectionFactory connectionFactory = 
SOAPConnectionFactory.newInstance();
SOAPConnection connection = connectionFactory.createConnection();
MessageFactory factory = MessageFactory.newInstance();
FileInputStream inputStream = new FileInputStream(new 
File("some_xml_file.xml"));
MimeHeaders headers = new MimeHeaders();
headers.addHeader("Content-Type", "text/xml");
SOAPMessage message = factory.createMessage(headers, inputStream);
SOAPMessage reply = connection.call(message, new URLEndpoint("some_url"));
-------------

Really easy!
