I have successfully installed Openstack on my Ubuntu server, however I have errors trying to access the swift installaion using jclouds.

Trying to troubleshoot it from the command line, I got the following error :

ERROR: openstack The resource could not be found. (HTTP 404) (Request-ID: req-0f24312c-74de-483a-b8b7-b578c8bfb37f)

relevant parts of the code is :

public Swifter() {
      Iterable<module> modules = ImmutableSet.<module>of(
            new SLF4JLoggingModule());

      String provider = "openstack-swift";
      String identity = "admin:admin"; // tenantName:userName
      String credential = "OVnAhlgYvTmWTVPAgUXm";

      swiftApi = ContextBuilder.newBuilder(provider)
            .endpoint("http://172.16.20.171:35357/v2.0")// or 172.16.20.171
            .credentials(identity, credential)
            .modules(modules)
            .buildApi(SwiftApi.class);
   }

   private void createContainer() {
      System.out.println("Create Container");

      ContainerApi containerApi = swiftApi.getContainerApi("RegionOne");
      CreateContainerOptions options = CreateContainerOptions.Builder
            .metadata(ImmutableMap.of(
                  "key1", "value1",
                  "key2", "value2"));

      containerApi.create(CONTAINER_NAME, options);

      System.out.println("  " + CONTAINER_NAME);
   }

The output i get :

Create Container
