In the following subsections we are going to walk through many different scenarios to illustrate the distributed tracing in action, starting from the simplest ones and finishing with asynchronous JAX-RS services. All examples assume that configuration  configuration has been done (see please Configuring Client and Configuring Server sections above).

Example #1: Client and Server with default distributed tracing configured

In the first example we are going to see the effect of using default configuration on the client and on the server, with only HTraceClientProvider  and HTraceProvider registered. The JAX-RS resource endpoint is pretty basic stubbed method:

@Produces( { MediaType.APPLICATION_JSON } )
@GET
public Collection<Book> getBooks() {
    return Arrays.asList(
        new Book("Apache CXF Web Service Development", "Naveen Balani, Rajeev Hathi")
    );
}

The client is as simple as that:

final Response response = client
    .target("http://localhost:8282/books")
    .request()
    .accept(MediaType.APPLICATION_JSON)
    .get();

The actual invocation of the request by the client (with process name jaxrsclient/192.168.0.100) and consequent invocation of the service on the server side (process name jaxrsserver/192.168.0.100) is going to generate the following traces.
