/**
 * Philosophy
 * Jemboss webservices are implemented here as re-entrant synchronous SOAP
 * exchanges. It is up to the user of the class whether these exchanges
 * are executed in their own thread to effect background processing
 * functionality.
 *
 * Things to do
 * Test threadability
 * Standardise the exceptions (currently errors are output on stdout)
 * Allow server configuration
