In this blog, I am covering consuming an external OData service (Northwind) from a CAP Java application using SAP BTP destination service.

Destinations: contain the connection details for the remote communication of an application.


  • Trial account on BTP

  • Java application built using SAP Cloud Application Programming Model (CAP) deployed to SAP Business Technology Platform.

Create a Destination on BTP cockpit:

  • Go to BTP subaccount -> space in which app is deployed -> instances -> create


Create destination service instance


  • Once the service instance is created, click on instance name -> select destinations -> new destination


  • Go to Referencing apps -> Click on bind instance -> select name of deployed application -> save

Consuming the destination in java code:

  • Add/make sure this dependency is added you your pom.xml


  •  We have already configured the connection information with destination northwind_api. SAP Cloud SDK provides DestinationAccessor to retrieve destination info.

@RequestMapping(value = "/getProducts")
public String getProducts() {
String DESTINATION_NAME = "northwind_api";

try {
HttpDestination destination =
HttpClient client = HttpClientAccessor.getHttpClient(destination);
HttpResponse httpResponse = null;
try {
httpResponse = client.execute(new HttpGet());
if (httpResponse.getStatusLine().getStatusCode() == 200) {
BufferedReader reader = new BufferedReader(
new InputStreamReader(httpResponse.getEntity().getContent()));
StringBuilder result = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
return result.toString();
} catch (IOException e) {
return "IOException: " + e.getMessage();
} catch (DestinationNotFoundException | DestinationAccessException e) {
return e.getMessage();
return null;


  • Got the response as below on hitting "/getProducts" endpoint


This blog should give you a clear idea on how to consume destinations in SAP Cloud Platform Cloud Foundry environment from java code using DestinationAccessor class provided by SAP cloud SDK.
