Chiba Web 3.0.0b2
Chiba Web 3 is a new major release of the Chiba server-side XForms implementation, coming with a brand new
- Chiba is now using Dojo Toolkit Version 1.2.3 (latest) which vastly improves the quality of the UI.
to load many parts of the application libs from Google. Dojo components can be seemlessly integrated
with XForms processing to add the last missing pieces that make up a full application.
- Large parts of the Core processor and the Web layer have been heavily refactored and now provide a
cleaner API and simplified parts of the Code. Extensibility of the Java API has been greatly improved.
- The CSS system has been reworked for consistency and there's new documentation available.
We boldly call it a beta ;) Please handle with care.
You are strongly encouraged to use Chrome 4+, Safari 3+ or Firefox 2+ for viewing.
What is it ?
- a ToolKit combining XForms, AJAX and the Dojo toolkit
- combines an attractive and extensible set of cross-browser widgets with the rich MVC Model of XForms
- Rapid web application building in a declarative way
Chiba is an Open Source Java Implementation of the W3C XForms standard 'that represents the next generation of forms for the Web'. [Abstract of the XForms PR]
Chiba uses Direct Web Remoting DWR
For page authors absolutely no knowledge of AJAX techniques is required. All the wiring is automatic.
The Dojo Toolkit
The Dojo toolkit
By bundling the Dojo Toolkit it's now possible to use the full set of Dojo controls to build
application-like UIs with full AJAX and XForms support without needing to write a single line of script
or Java code.
A complete, fine-grained system of CSS classes allows to control the layout and styling of
the whole UI. A quick reference card shows all classes available on one sheet.
The Chiba architecture is minimal-intrusive. There's no coding needed to integrate XForms processing
into your webapp while still giving you a lot of hooks when tied integration is wanted.
There are no plugins or other installations needed to use full XForms in your browser today. It will work
for the major browsers (IE6.0+, Safari 3.0+, FF 2.0+ and others).
As HTTP handling and full XML support are built-in it's a matter of minutes to connect a Chiba page to
a REST service. XForms is an ideal fit when working with such architectures.
Chiba nicely supports the XForms Rest XQuery (XRX) paradigm. XQueries can directly be used as data and
parameterized through your XForms. Chiba nicely integrates with the popular Open Source XML database
the best way a request/response interface can give you.
It's easy to integrate new components and enhance the set of available controls. Not only all Dojo controls
Data typing will come to your pages by simple declarations. The
full set of XML Schema types plus your own extensions can be used. XForms constraints allow to apply further
facets to any data node. Along with the capability to execute calculations in a similar declarative way
you never have to worry about invalid data in your backend again.
Both XForms and Dojo follow a declarative approach to page building. This is a perfect match - both can co-exist
with interference and interact in a controlled manner. No manual scripting will be needed unless you like
to write your own components.
Usually some sort of persistence backend will make your apps powerful and you'll need to seemlessly
integrate with arbritary datasources. Chiba already supports the most common protocols but can also
be easily extended to dock to any datasource. These connectors can be plugged by configuration and
can be combined with any other connector in a page.
Starting with Chiba Web 3.0.0b2 Chiba will be available under the liberal BSD and Apache 2 licenses. This
allows unlimited commercial use. Professional support will be available from the admins of the project.
