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> 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>. <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>deleteNode</code> deletes 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>. <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. <PRE> Name name = se.createName("GetLastTradePrice", "WOMBAT", "http://www.wombat.org/trader"); </PRE><P><P><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><A NAME="field_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Field Summary</B></FONT></TD></TR></TABLE> <A NAME="fields_inherited_from_class_org.w3c.dom.Node"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Fields inherited from interface org.w3c.dom.<A HREF="http://java.sun.com/j2se/1.4/docs/api/org/w3c/dom/Node.html" title="class or interface in org.w3c.dom">Node</A></B></TD></TR>⌨️ 快捷键说明
