| * <LI>A <code>SOAPPart</code> object |
| * <LI>A <code>SOAPEnvelope</code> object |
| * <LI>A <code>SOAPBody</code> object |
| * <LI>A <code>SOAPHeader</code> object |
| * </UL> |
| * In some cases, specialized MessageFactory objects may be obtained that produce messages |
| * prepopulated with additional entries in the <code>SOAPHeader</code> object and the |
| * <code>SOAPBody</code> object. |
| * The content of a new <code>SOAPMessage</code> object depends on which of the two |
| * <code>MessageFactory</code> methods is used to create it. |
| * <UL> |
| * <LI><code>createMessage()</code> <BR> |
| * This is the method clients would normally use to create a request message. |
| * <LI><code>createMessage(MimeHeaders, java.io.InputStream)</code> -- message has |
| * content from the <code>InputStream</code> object and headers from the |
| * <code>MimeHeaders</code> object <BR> |
| * This method can be used internally by a service implementation to |
| * create a message that is a response to a request. |
