What Can You Do with Cyberaide JavaScript?

Cyberaide JavaScript provides an API for adding Grid functionality to Rich Client Applications using JavaScript. You can

• Build a Grid mash-up. The included example jsportal.html provides a sophisticated mash-up example.

• Build a Grid gadget using the Google Gadget and Open Social specifications. We include three example gadgets: cyberaideJobman.xml, cyberaideFiletransfer.xml, and cyberaidejsportal. These can be added to iGoogle or to the OGCE Gadget Container

.

Project Information

• Project information on Cyberaide JavaScript COG development is available from http://cyberaide.org/projects/cyberaide/cyberaide-javascript.

• The Cyberaide Google Code Web site is http://code.google.com/p/cyberaide/. Note this includes sibling projects.

• The code repository (SVN) is http://cyberaide.googlecode.com/svn/trunk/project/javascript/. This can be used for anonymous checkouts.

Prerequisites

Cyberaide JavaScript's download is mostly self-contained, with the following exceptions.

• • If getting the code from SVN, you need an SVN client tool. The examples below show the command line client.
  • You need Java SDK version 1.6 or higher, but all other software is included in the download.
  • Cyberaide JavaScript is designed to work with common Grid services (MyProxy, GRAM, GridFTP), so you need these installed somewhere (such as the NSF TeraGrid ).
  • However, you do not need to install additional clients or command line tools to these services on your portal server.

Get the Code

Choose from one of the options below.

• (Option A) Get the SC09 release code (stable) from SVN:
