The SOAP 1.2 specification adds a third attribute to a SOAPHeaderElement, relay. This attribute, like mustUnderstand, is a boolean value. If it is set to true, it indicates that the SOAP header block must not be processed by any node that is targeted by the header block, but must only be passed on to the next targeted node. This attribute is ignored on header blocks whose mustUnderstand attribute is set to true or that are targeted at the ultimate receiver (which is the default). The default value of this attribute is false.
For example, you could set the relay element to true for the billingHeader in the code fragment in The actor Attribute (also changing setActor to setRole):
QName billing = new QName(nameSpaceURI, "billingDesk", nameSpace); SOAPHeaderElement billingHeader = header.addHeaderElement(billing); billingHeader.setRole("http://gizmos.com/billing"); billingHeader.setRelay(true);
This fragment produces the following XML:
<ns:billingDesk xmlns:ns="http://gizmos.com/NSURI" env:relay="true" env:role="http://gizmos.com/billing"/>
To display the value of the attribute, call getRelay:
System.out.println("relay is " + headerElement.getRelay());
