Get oAuth token JAVA SDk

Hi corvettemina,

Fully automatic authentication has never been and likely  will never be. Particular user that gives right to your application to do something on his account, needs to confirm it somehow (such thing can't be fully automatic - or I don't know for such, at least). About "long live access token"; if you have some exist, you can still use it as... always. If you mean to get a new one, it's impossible already. Such tokens, even usable still, are  considered obsolete and likely will be dropped at some future point. You can see "how to use a refresh token in the java sdk" in some of the examples there (here, for instance, to receive one and here for usage in action).

Hope this helps.
