Problem connecting HCP to SCC

[former_member182650]

Hi folks,

I'm trying to create this demo scenario:

- SAPUI5 app deployed on Hana Cloud Platform accessing GW Demo System throught SAP Cloud Connector.

- GW is this demo system (previously I've been registered 😞 https://sapes1.sapdevcenter.com/sap/opu/odata/sap/ZGWSAMPLE_SRV/?sap-ds-debug=true

I've followed this steps:

1 - Install SAP JVM

2 - Install SAP Cloud Connector

3 - Connect SAP Cloud Connector to hanatrial account:

4 - Create a destination on hanatrial account:

5 - Create a SAPUI5 app with HANA Studio SP7 and deploy to hanatrial account. To verify backend connection I've tried to create this example servlet:

SAP HANA Cloud Platform

public class BackendServlet extends HttpServlet {
  private static final long serialVersionUID = 1L;


  public BackendServlet() {
  }


  /**
  * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse
  *      response)
  */
  protected void doGet(HttpServletRequest request,
  HttpServletResponse response) throws ServletException, IOException {
  try {
  Context ctx = new InitialContext();
  HttpDestination destination = (HttpDestination) ctx.lookup("java:comp/env/gwdemotestdestination");
  HttpClient createHttpClient = destination.createHttpClient();
  HttpGet get = new HttpGet("");
  HttpResponse resp = createHttpClient.execute(get);
  HttpEntity entity = resp.getEntity();
  String respToString = EntityUtils.toString(entity);
  response.getWriter().println(respToString);
  } catch (DestinationException e) {
  throw new RuntimeException(e);
  } catch (NamingException e) {
  throw new RuntimeException(e);
  }
  }


  /**
  * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse
  *      response)
  */
  protected void doPost(HttpServletRequest request,
  HttpServletResponse response) throws ServletException, IOException {
  }
}

note The full stack trace of the root cause is available in the SAP logs.

I would to know which step could be missing.

Thanks in advance!

Hi Angel,

this exception means that your destination doesn't have the

CloudConnectorVersion = 2 property.

From your screenshots it can be seen the property is there

So maybe there is a cached destination.

Did you by any chance used the command line for creating destinations?

Please try restarting your application.

Thanks!

I've saved a destination with value 1 and modified with value 2 without restarting

Kind regards

Hi Angel,

the exception indicates that CloudConnectorVersion 1 is used. In your configuration though, I can see a value of 2, which would fit. That looks strange. Do you have just updated the config? There is a cache of 5 minuites so that still the old variant is used. Can yoou try again and increase traces for your application so that we have more information, why it is not trying to use the correct runtime.

Best regards,

Markus
