I'm trying to build a simple java client program using the partner WSDL. I built stubs from the Partner WSDL file. I downloaded the WSC .jar file and added it to my build path. I'm still getting Connector cannot be resolved and PartnerConnection cannot be resolved.  I would have thought they were in the Partner WSDL file but I don't see them there.

Anyone know where I should go for those or why I don't have them in my project when I have the stubs from the partner WSDL and the force-wsc-44.0.0.jar?
 

import com.sforce.soap.partner.*;
import com.sforce.soap.partner.sobject.*;
import com.sforce.ws.*;
import com.sforce.ws.ConnectorConfig;

class SalesforceHelper {

    public SalesforceHelper () {

        ConnectorConfig config = new ConnectorConfig();
        config.setUsername("username");
        config.setPassword("password");

        PartnerConnection connection = Connector.newConnection(config);
    }

}
