Who The Apache Software Foundation (ASF): all-volunteer developers, stewards, and incubators of nearly 150 Open Source projects and initiatives.

What Version 6.0 release of Apache Wicket, the Open Source component-based Java Web application framework in use at Symantec, Walmart, Netherlands Internal Revenue Service, and more.

Why Apache Wicket v6.0 is the latest version of the popular Java component-oriented Web framework used by thousands of development shops around the world, including an array of large and small organizations such as Symantec Corporation, Walmart, Vegas.com, email provider GMX, and the Dutch Internal Revenue Service. Providing an Open Source, component-oriented development model for Web application development, Wicket eases the creation and maintenance of complex Java Web applications; v6.0 enhances core functionality and offers many new features, from OSGi compatibility to AJAX attributes to Big Data support. 

"This release delivers a reinvigorated implementation of our client side API that enables developers to integrate rich JavaScript libraries and components with minimal effort. We have updated and broadened the capability and flexibility of many existing features throughout the framework," said Martijn Dashorst, Vice President of Apache Wicket.

Where As with all Apache products, Apache Wicket is overseen by a self-selected team of active contributors; a Project Management Committee (PMC) guides the Project's day-to-day operations, including community development and product releases. The Apache Wicket PMC has released a new Technical Fact Sheet on Apache Wicket v6.0 at https://blogs.apache.org/foundation/entry/apache_wicket_v6_0_0

Apache Wicket v6.0.0 is the 6th major release of the popular open source Java web framework. Numerous enhancements make Apache Wicket v6.0.0 a solid choice for web

development:

• Out-of-the box JQuery integration 
• Complete control over AJAX requests
• Improved event registration in browsers
• Support for large datasets in components
• Dependency management for client side javascript libraries
• Experimental support for websockets

Additional features include a customizable client-side API, improved feedback messages, correct packaging for OSGi compatibility and improved initialization of plugins. Highlights include:

Java 6 required -This release moves the minimum required Java version to Java 6. This means that Wicket applications running on earlier Java versions meaning to upgrade, also need to upgrade their Java runtime.

Revamped Wicket AJAX now leverages JQuery - Wicket's custom AJAX JavaScript library has been re-implemented using JQuery. This makes it easier to integrate JQuery plugins into Wicket applications. With the new AJAX implementation it is possible to provide your own version of JQuery should the need arise, or even to replace the whole Wicket client side AJAX implementation.

Browser event registration replaces inline events - Wicket now uses JavaScript event registration instead of inline attributes for AJAX components. This enables multiple event listeners to be attached to a markup tag, cleans up the rendered markup considerably and reduces the amount of generated markup.

IDataProvider now uses long instead of int - The IDataProvider<T> interface and implementations now use long instead of int for index and size parameters to better line up with the Java Persistence API and other persistency frameworks. Big data is now possible with Wicket!

${label} replaces ${input} in feedback messages - Previous Wicket versions used the input that was provided by users in error messages when validations failed. This led to error messages like "1234a is not a valid number". In Wicket 6 the feedback messages use the label of the invalid form component instead. You can set the label by calling setLabel() on the form

component. If no label is provided, Wicket defaults to displaying the component identifier. This changes the error message to "Phonenumber is not a valid number".

Resources can declare dependencies - It is now much easier to create resource contributions with dependencies, for example a JQuery plugin can declare a dependency on JQuery and other resources such as embedded style sheets. Users of such resources don’t have to provide these dependencies themselves, and the dependencies are linked in the appropriate order.

Packaged resources will use minimized version automatically - When a minimized JavaScript resource is available (filename.min.js – add the .min part to the filename before the extension), Wicket will automatically use the minimized version when running in deployment mode, while using the non-minimized version for development mode.

Experimental websocket implementations - This release also includes two experimental websocket implementations: one using Atmosphere as a bridge for browsers and containers that don’t support websockets natively and one for containers and browsers that have native websocket support.
