setODPCertificateChallengeListener( IODPCertificateChallengeListener ) method

Syntax

Parameters

• oListerner – Instance of IODPCertificateChallengeListener.

Exceptions

• ODPException class –

Examples

• Example 1 –

  ODPClientConnection ocl = ODPClientConnection.getInstance();
  IODPCertificateChallengeListener certListener = new ODPCertificateChallengeListenerImpl();
  ocl.setODPCertificateChallengeListener( certListener );
  1. Implement the listener
  public class ODPCertificateListener implements IODPCertificateChallengeListener
  {
  // callback method for certificate verification
  public boolean isServerTrusted(ODPCertInfo[] certCredentials)
  {
  Log.i("Do you trust the server for
  credentials:"+certCredentials.toString()); //display these credentials for the server
  return true; // return true or false depending on userinput from the UI
  }
  }
  2. Register a listener to verify server certificate
  ODPCertificateListener odpCertificateListener = new ODPCertificateListener();
  ODPUserManager.getInstance().setODPCertificateChallengeListener(odpCertificateListener);

Usage

When a client attempts to connect to a host (like a relay server), this connection is authenticated with a basic authentication challenge. To verify if the server certificate is trusted or not, the application registers a listener object with the OData SDK. If the server certificate is trusted, the connection is successful. If the server certificate is not trusted, it is rejected and the connection fails. See "Configuring Unwired Server to use Relay Server" in SAP Control Center for SAP Mobile Platform for information on the configuration of relay server properties.
