How to use (Bookmarklet method):

1: Upload cmd.jsp to a java web app server

How this happens is up to you.

2: Browse to /[wherever you put it]/cmd.jsp
3: Use a bookmarklet to add javascript to the page

Add the code below as a link to your bookmarks bar and click it when you are on the cmd.jsp page. It will add the javascript which provides the user interface and client side functionality. (This contains a.js encoded in base64 for reliable copy/pasting.)
