+### Construction of OData Client

+ ODataClient odata = ODataClientFactory.getClient();
+ odata.getConfiguration().setDefaultPubFormat(ContentType.APPLICATION_JSON);
+
+### Construction of a client entity and create request
+
+ ClientObjectFactory factory = getClient().getObjectFactory();
+ final ClientEntity entity = factory.newEntity("OData.Demo.Manufacturer");
+ entity.getProperties().add(factory.newPrimitiveProperty("Name",
factory.newPrimitiveValueBuilder().buildString("MyCarManufacturer")));

+ final URI targetURI =
getClient().newURIBuilder(serviceUrl).appendEntitySetSegment("Manufacturers").build();
+ final ODataEntityCreateRequest<ClientEntity> createRequest =
getClient().getCUDRequestFactory().getEntityCreateRequest(targetURI, entity);
+
+### Add a create request to a changeset
+
+ BatchManager payloadManager =
getClient().getBatchRequestFactory().getBatchRequest(serviceUrl).payloadManager();
+ final ODataChangeset changeset = payloadManager.addChangeset();
+
+ changeset.addRequest(createRequest);

+### Construction of a query request
+
+ final URI targetURI =

+
+ payload.addRequest(queryReq);
+
+### Fetch the batch response
+
+ final ODataBatchResponse response = payload.getResponse();
