AJAX Enabled GrimoiresScript Interpreter

I implemented a toy language to handle Grimoires registry, which now I renamed as GrimoiresScript. Now I created a web-based GrimoiresScript interpreter, using AJAX to communicate between HTML page that takes in user input, and server-side JSP that invokes GrimoiresScript interpretation engine. The implementation follows the example in w3schools' AJAX tutorial.

AJAX is nothing but, or mostly a JavaScript RMI, which enables HTML pages to invoke remote methods.
