Subject: JSP 2D Taglib Released -- Script Java 2D API from your JSP with
JavaScript
I'm proud to announce a JSP taglib that I thought the Struts mailing list
might like to hear about.
http://ditchnet.org/2d
JSP 2D Taglib Released -- Script Java 2D API from your JSP with JavaScript
With the Ditchnet JSP 2D Taglib, your web applications now have full
access to the Java 2D API for dynamically rendering beautiful graphics
primitives directly in your web page without limitation. Yes, the web page
itself becomes a canvas on which you can leverage the full power of the
Java 2D API for graphics. Literally all browsers are supported... no
Applets, JavaScript, Ajax, Flash, Plug-Ins, Cookies, Lazlo, Ruby on Rails
or any other hackery required on the client! (We keep our hackery on the
server, thank you.)
The 2D taglib is similar in concept to the <canvas> tag pioneered by Apple
in Safari 2 and later accepted by the WHATWG in one of their specs... it
allows web page authors to script graphics primitives directly in the HTML
source of a page using JavaScript (although the user need not have
JavaScript enabled in her browser).
Web page authors can use all of the nice scripting features of the
familiar JavaScript language (native collection types like Arrays and
Object dictionaries, and dynamic typing) to harness the massively powerful
Java 2D API -- and the result renders directly in the web page!
