Although the output is tightly packed together and hard to read, youcan clearly see

the request 2011 and response MMXI values.

Each of Listing 11-18 's toInteger() and toRoman() methods extracts the re-

sponse value by first checking the response message's body to learn if it describes a

fault. This task is accomplished by invoking SOAPBody 's boolean hasFault()

method.Ifthismethodreturnstrue, SOAPBody 's SOAPFault getFault() method

iscalled toreturn anobject that describes the fault interms ofthe SOAPFault inter-

face'smethods,and SOAPFault 's String getFaultString() methodiscalled

to return the string-based fault message.
