Apache Click's at 2.3.0

The developers of the Apache Click framework, described as a modern Java EE web application framework, have released version 2.3.0, adding Ajax support, page actions and light weight stateful controls. The release comes ten months after the last version of Click (2.2.0) was published.

Click, which became a Top-Level Project last year, takes the page and component design approach to web development, where a selection of controls reside on a page and generate events for an event based programming model. Click uses no JSP or MVC patterns deliberately; the developers feel that the combination of JSP and MVC has held back Jave EE web development.

The new Ajax support allows developers to configure the server side of Click to handle Ajax requests from browsers though it leaves the client side of the request up to the developer. Page Actions allow pages to be updated with server provided information and can work with the Ajax support. The lightweight stateful controls replace Click's previous support for stateful pages by allowing developers to preserve information about the user's session. Other enhancements include new documentation, improved form field processing and support for multiple tabbed panels on one page. Notes on upgrading to version 2.3.0 are available.

An example page contains demonstrations of the new, and old, functionality in Click. Available under the Apache 2 licence, Click can be downloaded from Apache Foundation mirrors.
