A. assign the properties to a connection factory and create the connection 

B. specify the URL of the UDDI registry in the properties, assign the properties to a connection factory, and create the connection 

C. specify the URL of the UDDI registry in the properties, assign the properties to a connection factory, assign the properties to a service binding, and create the connection 

D. specify the URL for the UDDI registry and the tModel in the properties, specify the search criteria for services, assign the properties to a service binding, and create the connection
