None of the different ways of which are either a) compatible or b) widely supported. Particularly not in Java, as the OP was asking.

Like I said, trying to automate a GUI is a waste of time. GUIs are designed for humans, not computers, to use.

That’s why we have command lines and scripting (which are all just programming at different layers, of course). That’s how you automate things, building higher-level abstract machines on top of lower-level ones. GUIs are the end of the abstraction chain: you cannot build anything more on top of them.
