• org.apache.hello_world_soap_http
  This package name is generated from the http://apache.org/hello_world_soap_http target namespace. All of the WSDL entities defined in this target namespace (for example, the Greeter port type and the SOAPService service) map to Java classes in the corresponding Java package.
• org.apache.hello_world_soap_http.types
  This package name is generated from the http://apache.org/hello_world_soap_http/types target namespace. All of the XML types defined in this target namespace (that is, everything defined in the wsdl:types element of the HelloWorld contract) map to Java classes in the corresponding Java package.

This section describes how to write the code for a simple Java client, based on the WSDL contract above. To implement the client, you need to use the following stub classes:

...

For example, the below shows the Greeter service endpoint interface, which is generated from the Greeter port type defined in #Example1. For simplicity, #Example3 omits the standard JAXB and JAX-WS annotations.

CXF supports the following context properties:

Asynchronous Invocation Model

...

Customization enables you to modify the way the wsdl2java utility generates stub code. In particular, it enables you to modify the WSDL-to-Java mapping and to switch on certain features. Here, customization is used to switch on the asynchronous invocation feature. Customizations are specified using a binding declaration, which you define using a jaxws:bindings tag (where the jaxws prefix is tied to the http://java.sun.com/xml/ns/jaxws namespace). There are two alternative ways of specifying a binding declaration:

...

The implementation of handleResponse() shown in #Example11 simply gets the response data and stores it in a member variable, reply. The extra getResponse() method is just a convenience method that extracts the sole output parameter (that is, responseType) from the response.

#Example12 illustrates the callback approach to making an asynchronous operation call. Using this approach, the client invokes the operation by calling the special Java method, _OperationName_Async(), that returns a java.util.concurrency.Future<?> object and takes an extra parameter of AsyncHandler<T>.

...

The Future<?> object returned by greetMeSometimeAsync() can be used only to test whether or not a response has arrived yet - for example, by calling response.isDone(). The value of the response is only made available to the callback object, testAsyncHandler.
