How to Consume RESTfull webservice created in Oracle Database Cloud service?

KTM

Hi All,

I am trying to consume sample REST full web service from Oracle Database Cloud(oracle.example.hr     and URI template:  employees/{id}    ) service locally as follows

public class OracleCloudClientMain {

    public OracleCloudClientMain() {

        super();

    }

  

    public static void main(String[] args){

        getJSON();

      

    }

    private static void getJSON(){

        ClientConfig config = new DefaultClientConfig();

        Client client = Client.create(config);

       

    

        WebResource service = client.resource(getBaseURI());

        System.out.println(service.path("/7839").path("JSON").accept(MediaType.APPLICATION_JSON).get(String.class));

        System.out.println(service);

    }

  

    private static URI getBaseURI(){

        return UriBuilder.fromUri("https://trial56313.db.us1.oraclecloudapps.com/apex/hr/employees/").build();

      

    }

  

  

  

  

}
