Hey mate,
I also have our desination in the XML (our web.xml is quite big)
<resource-ref> <res-ref-name>sap_hcmcloud_core_odata</res-ref-name> <res-type>com.sap.core.connectivity.api.http.HttpDestination</res-type></resource-ref>
I am not sure if it important but if I remember correctly we used the latest SDK and we are using Java Web as server (not tomcat).
Quick question first 
is your user logged in in SuccessFactors ? (in other words, do you get to the successfactors login screen ?) It might just be as easy as the SSO is not configured ?
I made a quick working example here:
package com.sample.sfsf;
import static java.net.HttpURLConnection.HTTP_OK;
import java.io.IOException;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.security.auth.login.LoginContext;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import com.sap.core.connectivity.api.DestinationFactory;
import com.sap.core.connectivity.api.configuration.ConnectivityConfiguration;
import com.sap.core.connectivity.api.configuration.DestinationConfiguration;
import com.sap.core.connectivity.api.http.HttpDestination;
import com.sap.security.auth.login.LoginContextFactory;

}Cheers
