launch java applet just by using javascript with out applet integration

I am new to vaadin , I have to launch an applet on click of a button. I saw vaadion has addon for java applet. Instead of using vaadin applet addon, I am thinking call java script which uses deployJava.runapplet(…) ( and add deployJava.js and anyother required js files to header in application servlet. My button listner from page will call

JavaScript.getCurrent().execute(" applet launch js function...") Please advice.

I have the same question.
