This is the mime type of the interpreter you want to get. Batik
supports multiple script engines.

You are right this is a string, but the string is evaluated in the
global scope of the Interpreter. So the text can be any valid ECMA
script:
int clientX = 10;
int clientY = 10;
[...]
ctx.getInterpreter("text/ecmascript").
evaluate("evt = new function { this.clientX=" + clientX +
"; this.clientY=" + clientY + "; " + /* what ever else */
" }; mouseClick1(evt)");

I would carefully review the code in
AWTEventDispatcher.dispatchMouseEvent
this does what you want, and you should be able to use that code to make
your
own version using whatever info you have available.
