"createResource" is called for every invocation of the generated command line
wrapper operation, this initializes the "resource" variable.

Since "scope" is "Application" there is a single service instance serving all
requests, thus multiple simultaneous client calls create a race condition.

 * This class implements each method in the portType of the service.  Each
method call represented
 * in the port type will be then mapped into the unwrapped implementation which
the user provides
 * in the HelloWorldImpl class.  This class handles the boxing and unboxing of
each method call
 * so that it can be correclty mapped in the unboxed interface that the
developer has designed and
 * has implemented.  Authorization callbacks are automatically made for each
method based
 * on each methods authorization requirements.
