29/**
30 * A point-to-point connection that a client can use for sending messages
31 * directly to a remote party (represented by a URL, for instance).
32 * <p>
33 * The SOAPConnection class is optional. Some implementations may
34 * not implement this interface in which case the call to
35 * {@code SOAPConnectionFactory.newInstance()} (see below) will
36 * throw an {@code UnsupportedOperationException}.
37 * <p>
38 * A client can obtain a {@code SOAPConnection} object using a
39 * {@link SOAPConnectionFactory} object as in the following example:
40 * <pre>{@code
41 *      SOAPConnectionFactory factory = SOAPConnectionFactory.newInstance();
42 *      SOAPConnection con = factory.createConnection();
43 * }</pre>
44 * A {@code SOAPConnection} object can be used to send messages
45 * directly to a URL following the request/response paradigm.  That is,
46 * messages are sent using the method {@code call}, which sends the
47 * message and then waits until it gets a reply.
48 *
