/**
 * <p>
 * <b>PUBLIC:</b> JavasePackager extends {@link ProviderPackager}. It generates a simplified version<br>
 * of the JAX-WS Provider Endpoint that can be run using the Javase 6 'containerless' Endpoint API:
 * <pre>
 *   Endpoint endpoint = Endpoint.create(new @WebService or @WebServiceProvider);
 *   endpoint.publish(ENDPOINT_ADDRESS);
 *   QName serviceQName = new QName(serviceNamespace, serviceName);
 *   QName portQName = new QName(serviceNamespace, portName);
 *   service = Service.create(serviceQName);
 *   service.addPort(portQName, javax.xml.ws.soap.SOAPBinding.SOAP11HTTP_BINDING, ENDPOINT_ADDRESS);
 *   ...
 *   Dispatch<SOAPMessage> dispatch = testService.createDispatch(portQName, SOAPMessage.class,
 *     Service.Mode.MESSAGE);
 *   SOAPMessage response = dispatch.invoke(request);
 *   ...
 * </pre>
 * Package files generated by parent according to the following layout:
 * <pre>
 * ${PACKAGER_ROOT} - could be a directory or a <tt>.jar</tt> file:
 *    +---META-INF
 *    |       eclipselink-dbws-or.xml
 *    |       eclipselink-dbws-ox.xml
 *    |       eclipselink-dbws-sessions.xml
 *    |       eclipselink-dbws.xml
 *    |
 *    +---_dbws
 *    |       DBWSProvider.class
 *    |
 *    \---wsdl
 *            <i>swaref.xsd</i>                 -- optional if using attachments
 *            eclipselink-dbws-schema.xsd
 *            eclipselink-dbws.wsdl
