A SAAJ client calls the SOAPConnection method call on a SOAPConnection object to send a message. The call method takes two arguments: the message being sent and the destination to which the message should go. This message is going to the stock quote service indicated by the URL object endpoint.
java.net.URL endpoint = new URL("http://wombat.ztrade.com/quotes"); SOAPMessage response = connection.call(message, endpoint);
The content of the message you sent is the stock symbol SUNW; the SOAPMessage object response should contain the last stock price for Sun Microsystems, which you will retrieve in the next section.
