It would be more like:
ctx.getInterpreter("text/ecmascript").evaluate("mouseClick1(evt)");

If you want to pass 'evt' to mouseClick1 you need to include it
but you also need to set it up. So you would need to provide
clientX/Y, screenX/Y, target, currentTarget, etc. Assuming you use
any of those in your function (which is quite common).
If you can use the AWTEventDispatcher (I know it wants a Component
but it doesn't have to be a particularly "real" Component). Really
what it cares about is, when, modifiers, clickCount, x and y. So you
could construct a 'dummy' MouseEvent to pass to the dispatch method.

The GVTTree will be changed if the script changes anything without any
component.

When you get errors including the stack trace is essential if you
expect
any help. I suspect the problem is that
