As transmitted on the "wire", a SOAP * message is an XML document or a MIME message whose first body part is an * XML/SOAP document. * <P> * A <code>SOAPMessage</code> object consists of a SOAP part and optionally * one or more attachment parts. The SOAP part for a <code>SOAPMessage</code> * object is a <code>SOAPPart</code> object, which contains information used * for message routing and identification, and which can contain * application-specific content. All data in the SOAP Part of a message must be * in XML format. * <P> * A new <code>SOAPMessage</code> object contains the following by default: * <UL> * <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> * The SOAP part of a message can be retrieved by calling the method <code>SOAPMessage.getSOAPPart()</code>. * The <code>SOAPEnvelope</code> object is retrieved from the <code>SOAPPart</code> * object, and the <code>SOAPEnvelope</code> object is used to retrieve the * <code>SOAPBody</code> and <code>SOAPHeader</code> objects. * * <PRE> * SOAPPart sp = message.getSOAPPart(); * SOAPEnvelope se = sp.getEnvelope(); * SOAPBody sb = se.getBody(); * SOAPHeader sh = se.getHeader(); * </PRE> * * <P> * In addition to the mandatory <code>SOAPPart</code> object, a <code>SOAPMessage</code> * object may contain zero or more <code>AttachmentPart</code> objects, each * of which contains application-specific data. The <code>SOAPMessage</code> * interface provides methods for creating <code>AttachmentPart</code> * objects and also for adding them to a <code>SOAPMessage</code> object. A * party that has received a <code>SOAPMessage</code> object can examine its * contents by retrieving individual attachment parts. * <P> * Unlike the rest of a SOAP message, an attachment is not required to be in * XML format and can therefore be anything from simple text to an image file. * Consequently, any message content that is not in XML format must be in an * <code>AttachmentPart</code> object. * <P> * A <code>MessageFactory</code> object may create <code>SOAPMessage</code> * objects with behavior that is specialized to a particular implementation or * application of SAAJ. For instance, a <code>MessageFactory</code> object * may produce <code>SOAPMessage</code> objects that conform to a particular * Profile such as ebXML. In this case a <code>MessageFactory</code> object * might produce <code>SOAPMessage</code> objects that are initialized with * ebXML headers. * <P> * In order to ensure backward source compatibility, methods that are added to * this class after version 1.1 of the SAAJ specification are all concrete * instead of abstract and they all have default implementations. Unless * otherwise noted in the JavaDocs for those methods the default * implementations simply throw an <code>UnsupportedOperationException</code> * and the SAAJ implementation code must override them with methods that * provide the specified behavior. Legacy client code does not have this * restriction, however, so long as there is no claim made that it conforms to * some later version of the specification than it was originally written for. * A legacy class that extends the SOAPMessage class can be compiled and/or run * against succeeding versions of the SAAJ API without modification. If such a * class was correctly implemented then it will continue to behave correctly * relative to the version of the specification against which it was written. * * @see MessageFactory * @see AttachmentPart */ public abstract class SOAPMessage { /** * Specifies the character type encoding for the SOAP Message.
