Connect to TWx Server from Java SDK with user credentials

Hello everyone,

i am trying to establish a connection from my java Application to my TWx Server. I have been using the approach with the application key. Something like this:

ClientConfigurator config = new ClientConfigurator();
config.setUri(ServerUri);
config.setAppKey(MyAppKey);
config.ignoreSSLErrors(true);

Connection client = new ConnectionClient(config);
client.connect();

I would rather be able to log in with the user credentials which are assigned to an application key. Is there an easy way to do this? I have read about the Authentificators, but im not sure wether they are necessary for this (hopefully) simple scenario.

Thank you for your help.

Regards,

Dominik
