Hi

You might have different CXF distributions on the classpath ?

Cheers, Sergey

Dear All,

I am trying to develop restful webservices. I have followed the tutorial:

http://svn.apache.org/viewvc/cxf/trunk/distribution/src/main/release/samples/jax_rs/basic/src/main/java/demo/jaxrs/server/Server.java?revision=1490431&view=markup

Everything seems good, the Server is running. However, whenever I try to
create a client with the following code:

JAXRSClientFactoryBean client = new JAXRSClientFactoryBean();

client.setAddress("http://localhost:9000/repositoryservice/datafromenvironment";);
client.setResourceClass(RepositoryService.class);
RepositoryService repos = client.create(RepositoryService.class);

I have the following error:

Exception in thread "main" java.lang.NoSuchMethodError:

My classes are:

@Path("/repositoryservice/")
public interface RepositoryService {

     @POST
     @Path("/datafromenvironment/")
     Response addDataFromEnvironment(Data data);

     @GET
     @Path("/Hello/{name}")
     String sayHello(@PathParam("name") String name);

}

and

public class RepositoryServiceImpl implements RepositoryService{

     private RepositoryImpl repos;

     public RepositoryServiceImpl() {
         initializeService();
     }

     @Override
     public Response addDataFromEnvironment(Data data) {
         repos.openConnection();
         repos.Insert(data);
         repos.closeConnection();
         return Response.ok(data).build();
     }

     @Override
     public String sayHello(String name) {
         return "hello " + name;
     }

     private void initializeService(){
         this.repos = new RepositoryImpl();
     }

}

Do you have any suggestion?

Thank you for the help.

BR,

Giovanni
