  1. PHOBOS Javascript Engine By Daniel Reeves

  2. What is Phobos? • Lightweight application framework for Java • Used by NetBeans • Supports multiple scripting languages • Focuses mainly on JavaScript • Can be put in any servlet container

  3. Architecture Overview

  4. Why Use Phobos? • Universal to most scripting languages • Auto generates a skeletal web application for the user to create • Users can add a number of different prebuilt AJAX or javascript models such as jMaki and Dojo • Easy to use URL mapping • Multilingual- JSR-223-based

  5. Setting up Phobos • Netbeans module Addon • Uses predefined libraries and setups to initialize the web application structure. • Defines any additional class structure elements for the web application (CSS files)

  6. How it Works • At the first page request, index.js redirects and creates the controller for the application. • The controller defines all the methods within the controller’s javaScript file • The controller then renders the web application through the show() method • Show() renders the embedded Javascript file in the application, which defines what the user sees. • The application rerenders when POST is called.

  7. Index.js • library.httpserver.sendRedirect(library.httpserver.makeUrl("/list/show"));

  8. Show() • library.view.render({view: "list.ejs", layout: "layout.ejs"});

  9. Example: Calculator

  10. Using AJAX with Phobos • Phobos can easily do AJAX xhr requests • Example: AJAX List
