I am creating a client / server application, I start my first connection to the server from a jFrame (LogIn), now I want that same connection to pass to another JFrame (MainPage) so that I do not have to close the connection and then have to open a new. it's possible ? or how could I implement this ... is that my application is based on a user accessing the system through a login form and then goes to the main page where he queries a database.
