Welcome to Wicket

Wicket is a Java web application framework that takes simplicity, separation of concerns and ease of development to a whole new level. Wicket pages can be mocked up, previewed and later revised using standard WYSIWYG HTML design tools. Dynamic content processing and form handling is all handled in Java code using a first-class component model backed by POJO data beans that can easily be persisted using your favourite technology.

NB. this is the documentation of a fixed release. The latest and greatest of Wicket can be found at our main project page .

Latest News

August 29, 2005 - Maintenance release Wicket 1.0.3 available

A minor bugfix release has been issued for PageableListViewNavigation. The 1.0.3 version doesn't have any other improvements or fixes.

If you are using Wicket 1.0 and use the PageableListViewNavigation or the PageableListViewNavigator, then we advise you to upgrade to this version. Note that when you upgrade from 1.0.1, you may experience some backwards incompatibilities, as outlined in the 1.0.2 release notes.

August 22, 2005 - Maintenance release Wicket 1.0.2 available

The Wicket development team has released the second maintenance release of the Wicket 1.0 branch. This release fixes some bugs, and with that introduces one API breaking change:

  • newChoiceItem does not use object parameter but selects directly from list Issue: 1263892. Thanks to Arjan Zwaan.
  • Backport: AbstractDetachableModel doesn't propogate attach/detach Issue: 1253113.
  • Backport: serialization bug in LocalizedImageResource
  • Backport: possible NullPointerException in DynamicImageResource.getResourceStream()
  • Backport: catch if session is saved to disk and reloaded again but locale is changed
  • fix for classloading problems that caused problems loading markup/ resources for components that were loaded by another classloader than the current one.
  • Backport: closed FileOutputStream in wicket.util.file.Files in finally block
The API change involves the IResourceStreamLocator interface, where the locate method now takes a ClassLoader as an extra parameter. Passing in null will use the context classloader.

So while this is a maintenance release, please make sure your code still compiles with this release.

Juli 17, 2005 - Maintenance release Wicket 1.0.1 available

The Wicket development team has released the first (and probably last) maintenance release of Wicket 1.0. This release fixes some bugs and adds some missing functionality:

  • Only validate components that are visible
  • FeedbackPanel: made some methods that were not meant for overriding final, and added methods that make extending feedbackpanel easier
  • fixed bug in AbstractPropertyModel which gave problems using custom converters (overriding getConverter for a component) with compound property models
  • ComponentStringResourceLoader: resources are now inherited from parent classes when components have been subclassed
