access to the naming services available to clients in a J2EE environment through

JNDI APIs. See Code Example 5.3.

Stub stub = (Stub)(new OpcOrderTrackingService_Impl().

getOrderTrackingIntfPort());

OrderTrackingIntf port = (OrderTrackingIntf)stub;

Code Example 5.3

Accessing a Service with a Stub in J2SE and J2ME Environments

In addition, a J2SE or J2ME client can access a service by using the

javax.xml.rpc.ServiceFactory

 class to instantiate a stub object. Code Example

5.4 shows how a J2SE client might use a factory to locate the same order tracking

service.

ServiceFactory factory =  ServiceFactory.newInstance();

Service service = factory.createService(new QName(

"urn:OpcOrderTrackingService", "OpcOrderTrackingService"));

Code Example 5.4

Looking Up a Service in J2SE and J2ME Environments

Similarly, Code Example 5.5 shows how a J2SE application might use a

dynamic proxy instead of a stub to access a service. 

...

ServiceFactory sf = ServiceFactory.newInstance();

String wsdlURI = 

"http://localhost:8001/webservice/OtEndpointEJB?WSDL";

URL wsdlURL = new URL(wsdlURI);

Service ots = sf.createService(wsdlURL,

new QName("urn:OpcOrderTrackingService", 

"OpcOrderTrackingService"));
