Re: [lyo-dev] Consumer with auth
Stefan has documented the right way to approach this.   There is an enhancement open to create a convenience class in Lyo, but the method described should work.

Hi Alessio,

just for clarification you want to develop an OSLC Consumer that uses Basic Authentication against a service provider, right?

I just had a quick look at the source code of org.eclipse.lyo.oslc4j.client.OslcRestClient.
I did not implement it, but I am quite sure it should do the trick.

If you look at the constructor carefully.

public OslcRestClient(final Set<Class<?>> providers,
                              final String        uri,
                              final String        mediaType,
                              final int           readTimeout,
                              final ClientHandler ... handlers)

You will see you can pass a ClientHandler.
If one looks up the Wink Documentation (https://cwiki.apache.org/WINK/62-configuring-the-apache-wink-client.html)
that forms the basis of the OslcRestClient you can find 'org.apache.wink.client.handlers.BasicAuthSecurityHandler'.

Following the example there. You should be able to do something like that.
// Define your authentication mechanism and user credentials
BasicAuthSecurityHandler basicAuthHandler = new BasicAuthSecurityHandler();
 basicAuthHandler.setUserName("foo");
 basicAuthHandler.setPassword("bar");

//Set the other values for the OsclRestClient to your values
private static final String MEDIA_TYPE = OslcMediaType.APPLICATION_RDF_XML;
private final int timeout = 1500;
private final String queryBase = "http://hostname:port/ServiceProviderName/resources";
private final Set<Class<?>> providers = new HashSet<Class<?>>();
providers.addAll(JenaProvidersRegistry.getProviders());
providers.addAll(Json4JProvidersRegistry.getProviders());

//Initialize the OslcRestClient
final OslcRestClient oslcRestClient = new OslcRestClient(providers, queryBase, MEDIA_TYPE, timeout, basicAuthHandler);

Hope that helps. ;-)

Regards,
  Stefan
