Example 1-9. ch01/", "TimeServerImplService"); // Create, in effect, a factory for the service. create(url, qname); // Extract the endpoint interface, the service "port". getTimeAsElapsed()); The Java client uses the same URL with a query string as do the Perl and Ruby clients, but the Java client explicitly creates an XML qualified name, which has the syntax namespace URI:local name. A URI is a Uniform Resource Identifier and differs from the more common URL in that a URL specifies a location, whereas a URI need not specify a location.
Org). As the name indicates, the WS-I initiative is meant to help software architects and developers produce web services that can interoperate seamlessly despite differences in platforms and programming languages. Before going any further into the details, it will be helpful to have a sample WSDL for a document-style service, which then can be contrasted with the WSDL for the rpc-style TimeServer service. The use attribute will be clarified after the style attribute. The TimeServer service can be changed to a document-style service in two quick steps.
The Metro release has utility classes for tracking HTTP and SOAP traffic. This approach does not require any change to the client or to the service code; however, an additional package must be put on the classpath and a system property must be set either at the command line or in code. jar. Assuming that the environment variable METRO_HOME points to the jaxws-ri directory, here is the command that tracks HTTP and SOAP traffic between the TimeClient, which connects to the service on port 9876, and the TimeServer service.
