Enabling a Listener for HTTPS Support with Server Certificate Validation

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 SAP Mobile Server to use Relay Server in SAP Control Center for SAP Mobile Platform for information on the configuration of relay server properties.

Syntax

public void setODPCertificateChallengeListener(IODPCertificateChallengeListener oListener) throws ODPException;

Parameters

oListener – Listener object that implements ODPClientListeners.IODPCertificateChallengeListener interface.

Examples

Implement the listener –

Public class ODPCertificateListener implements IODPCertificateChallengeListener
{
	// callback method for certificate verification
    @Override
	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 
	}
		
}

Register a listener to verify server certificate –

ODPCertificateListener odpCertificateListener = new ODPCertificateListener();
ODPUserManager.getInstance().setODPCertificateChallengeListener(odpCertificateListener);
