•
Lightweight application framework for Java
Used by NetBeans
Supports multiple scripting languages
Focuses mainly on JavaScript

Architecture Overview
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
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)
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.
Index.js
• library.httpserver.sendRedirect(library.https
erver.makeUrl("/list/show"));
Show()
• library.view.render({view: "list.ejs", layout:
"layout.ejs"});
Example: Calculator
Using AJAX with Phobos
• Phobos can easily do AJAX xhr requests
• Example: AJAX List
