15.9 Java APIs

The following APIs are available for creating SOAP messages

javax.xml.soap	creating messages.

javax.xml.rpc.soap	binding

javax.xml.rpc.handler.soap	message handlers

Messages are held within javax.xml.soap.SOAPMessage objects and handled using the following classes: Detail, SOAPFault, Name, Node, SOAPBody, SOAPBodyElement, SOAPConstants, SOAPElement, SOAPEnvelope, SOAPFault, SOAPFaultElement, SOAPHeader, SOAPHeaderElement, and javax.xml.soap.Text.
<..message = .....>
SOAPFactory soapFactory =  SOAPFactory.newInstance();
MessageFactory factory =   MessageFactory.newInstance();
message = factory.createMessage();

SOAPHeader header = message.getSOAPHeader();
header.detachNode();

SOAPBody body = message.getSOAPBody();
Name bodyName = soapFactory.createName( "http://www.cis.ohio-state.edu" );
SOAPBodyElement bodyElement =  body.addBodyElement(bodyName);

Name name = soapFactory.createName("abc");
bodyElement.addChildElement(name);

<..inspect response ..>
SOAPBody soapBody = response.getSOAPBody();

The following classes are concerned with transporting SOAP messages.
- javax.xml.soap.SOAPConnectionFactory
- javax.xml.soap.SOAPConnection
<..response = reply for message ..>
URL endpoint =
    new URL ("http://gurari.cis.ohio-state.edu/servlet/GetSOAP");
SOAPConnectionFactory soapConnectionFactory =
                              SOAPConnectionFactory.newInstance();
SOAPConnection connection =  soapConnectionFactory.createConnection();
response =  connection.call(message, endpoint);
connection.close();

<..SendSOAP.java ..>

import java.net.URL;
import java.util.*;
import javax.xml.soap.*;

public class SendSOAP {
   public static void main(String[] args)  {
     try {
       SOAPMessage message;
       SOAPMessage response;
       <.message = ....>
       <.response = reply for message .>
       <.inspect response .>
     } catch (Exception e) { System.out.println( "error" );
} } }
