The Tuscany hello world WS client sample shows using the Tuscany SCA runtime in a J2SE environment invoking a web service.
The sample when run should simply display to the standard
output:

sca.module | Defines the SCA module, externalService and component. Defines for the HelloWorldServiceComponent component and the Java class that implements the component For the externalService it defines WSDL for the service, the Java interface provided by the service. The the HelloWorldServiceComponent is via a referenced wired to the externalService |
HelloWorldClient.java | Creates a Tuscany runtime and starts it. Obtains the module context which was defined by the sca.module file. From the module context locates the HelloWorldServiceComponent and then calls the getGreetings method to invoke the component. |
HelloWorldService.java | Defines the Java interface implemented by the component. |
HelloWorldServiceComponentImpl.java | It does not directly implement the service; instead it
has an SCA reference that is wired in the sca.module to an
externalService that will provide the service. The service providing the implementation is the helloworldws sample. |
tuscany-model.config | Maps the SCA Entry point WSDL to the physical WSDL file location. |
helloworld.wsdl | WSDL for the service. |
