Re: Access Java methods from JavaScript

The answer is in the error message, as far as I can tell.
I would guess that Microsoft's VM is autocasting, while Sun's
VM is not. I haven't done much Javascript, but maybe this would
work:

((com.baltimore .webrao.FirstAp plet)document.T estApplet1).pri ntString(msg)
