To Send SOAP Messages Using the JMS API

1. Import the MessageTransformer library.

   import com.sun.messaging.xml.MessageTransformer;

   This is the utility whose methods you use to convert SOAP messages to JMS messages and the reverse. You can then send a JMS message containing a SOAP payload as if it were a normal JMS message.

2. Initialize the TopicConnectionFactory, TopicConnection, TopicSession, and publisher.

   tcf = new TopicConnectionFactory();
   tc = tcf.createTopicConnection();
   session = tc.createTopicSession(false,Session.AUTO_ACKNOWLEDGE);
   topic = session.createTopic(topicName);
   publisher = session.createPublisher(topic);

3. Construct a SOAP message using the SOAP with Attachments API for Java (SAAJ).

   /*construct a default soap MessageFactory */
   MessageFactory mf = MessageFactory.newInstance();
   * Create a SOAP message object.*/
   SOAPMessage soapMessage = mf.createMessage();
   /** Get SOAP part.*/
   SOAPPart soapPart = soapMessage.getSOAPPart();
   /* Get SOAP envelope. */
   SOAPEnvelope soapEnvelope = soapPart.getEnvelope();
   /* Get SOAP body.*/
   SOAPBody soapBody = soapEnvelope.getBody();
   /* Create a name object. with name space */
   /* http://www.sun.com/imq. */
   Name name = soapEnvelope.createName("HelloWorld", "hw",
    "http://www.sun.com/imq");
   * Add child element with the above name. */
   SOAPElement element = soapBody.addChildElement(name)
   /* Add another child element.*/
   element.addTextNode( "Welcome to Sun Java System Web Services." );
   /* Create an atachment with activation API.*/
   URL url = new URL ("http://java.sun.com/webservices/");
   DataHandler dh = new DataHandler (url);
   AttachmentPart ap = soapMessage.createAttachmentPart(dh);
   /*set content type/ID. */
   ap.setContentType("text/html");
   ap.setContentId("cid-001");
   /**  add the attachment to the SOAP message.*/
   soapMessage.addAttachmentPart(ap);
   soapMessage.saveChanges();

4. Convert the SOAP message to a JMS message by calling the MessageTransformer.SOAPMessageintoJMSMessage() method.

   Message m = MessageTransformer.SOAPMessageIntoJMSMessage (soapMessage, 
   session );

5. Publish the JMS message.

   publisher.publish(m);

6. Close the JMS connection.

   tc.close();
