| /** |
| * The container for the SOAPHeader and SOAPBody portions of a |
| * <CODE>SOAPPart</CODE> object. By default, a <CODE> |
| * SOAPMessage</CODE> object is created with a <CODE> |
| * SOAPPart</CODE> object that has a <CODE>SOAPEnvelope</CODE> |
| * object. The <CODE>SOAPEnvelope</CODE> object by default has an |
| * empty <CODE>SOAPBody</CODE> object and an empty <CODE> |
| * SOAPHeader</CODE> object. The <CODE>SOAPBody</CODE> object is |
| * required, and the <CODE>SOAPHeader</CODE> object, though |
| * optional, is used in the majority of cases. If the <CODE> |
| * SOAPHeader</CODE> object is not needed, it can be deleted, |
| * which is shown later.</P> |
| * |
| * <P>A client can access the <CODE>SOAPHeader</CODE> and <CODE> |
| * SOAPBody</CODE> objects by calling the methods <CODE> |
| * SOAPEnvelope.getHeader</CODE> and <CODE> |
| * SOAPEnvelope.getBody</CODE>. The following lines of code use |
| * these two methods after starting with the <CODE> |
| * SOAPMessage</CODE> object <I>message</I> to get the <CODE> |
| * SOAPPart</CODE> object <I>sp</I>, which is then used to get the |
| * <CODE>SOAPEnvelope</CODE> object <I>se</I>.</P> |
| * <PRE> |
| * SOAPPart sp = message.getSOAPPart(); |
| * SOAPEnvelope se = sp.getEnvelope(); |
| * SOAPHeader sh = se.getHeader(); |
| * SOAPBody sb = se.getBody(); |
| * </PRE> |
| * |
| * <P>It is possible to change the body or header of a <CODE> |
| * SOAPEnvelope</CODE> object by retrieving the current one, |
| * deleting it, and then adding a new body or header. The <CODE> |
| * javax.xml.soap.Node</CODE> method <CODE>detachNode</CODE> |
| * detaches the XML element (node) on which it is called. For |
| * example, the following line of code deletes the <CODE> |
| * SOAPBody</CODE> object that is retrieved by the method <CODE> |
| * getBody</CODE>.</P> |
| * <PRE> |
| * se.getBody().detachNode(); |
| * </PRE> |
| * To create a <CODE>SOAPHeader</CODE> object to replace the one |
| * that was removed, a client uses the method <CODE> |
| * SOAPEnvelope.addHeader</CODE>, which creates a new header and |
| * adds it to the <CODE>SOAPEnvelope</CODE> object. Similarly, the |
| * method <CODE>addBody</CODE> creates a new <CODE>SOAPBody</CODE> |
| * object and adds it to the <CODE>SOAPEnvelope</CODE> object. The |
| * following code fragment retrieves the current header, removes |
| * it, and adds a new one. Then it retrieves the current body, |
| * removes it, and adds a new one. |
| * <PRE> |
| * SOAPPart sp = message.getSOAPPart(); |
| * SOAPEnvelope se = sp.getEnvelope(); |
| * se.getHeader().detachNode(); |
| * SOAPHeader sh = se.addHeader(); |
| * se.getBody().detachNode(); |
| * SOAPBody sb = se.addBody(); |
| * </PRE> |
| * It is an error to add a <CODE>SOAPBody</CODE> or <CODE> |
| * SOAPHeader</CODE> object if one already exists. |
| * |
| * <P>The <CODE>SOAPEnvelope</CODE> interface provides three |
| * methods for creating <CODE>Name</CODE> objects. One method |
| * creates <CODE>Name</CODE> objects with a local name, a |
| * namespace prefix, and a namesapce URI. The second method |
| * creates <CODE>Name</CODE> objects with a local name and a |
| * namespace prefix, and the third creates <CODE>Name</CODE> |
| * objects with just a local name. The following line of code, in |
| * which <I>se</I> is a <CODE>SOAPEnvelope</CODE> object, creates |
| * a new <CODE>Name</CODE> object with all three.</P> |
| * <PRE> |
| * Name name = se.createName("GetLastTradePrice", "WOMBAT", |
| * "http://www.wombat.org/trader"); |
| * </PRE> |
