Ready to work on download file

[Kaloyan96]

Is the there a file that can be downloaded from somewhere that can convert from java to JS?

And no, I don't need a set of instructions with a raw source code that then must be assembled into a working file, I need that working file. I've wasted over a week trying to "compile it myself".

I just need the file.
The one that is executable at the end.
Not the raw source code that I need to assemble myself.
Just the file.
