The code in the following listing illustrates how Jolt works with a service with an XML type buffer. Because Jolt does not look into the XML data stream, it is the programmer's responsibility to ensure that the data formats between the Jolt client and the XML service match. The example in the following listing assumes that a session object was already instantiated.
