??????? Wicket使開發(fā)者可以使用Java、HTML開發(fā)動(dòng)態(tài)的Web應(yīng)用程序，是基于Apache 2 協(xié)議的開源Web層框架。新版本修復(fù)了先前版本的一些Bug。并添加了一些新的特性。加入了對(duì)Portlet (JSR-168)的支持(本人很喜歡的一個(gè)功能，可是范例程序沒有同時(shí)發(fā)布，不過相信不會(huì)讓大家等太長(zhǎng)的時(shí)間)。

For improved reliability, instead of utilizing cookies and falling back on a quirky JavasScript, we now use window.name to detect whether we are in sync with the proper page map.
AjaxFormSubmitBehavior no longer incorrectly calls onSubmit() if an error occured during form processing (this aligns it with Button.onSubmit() semantic), instead a new onError() method will be called to allow for error related ajax target processing
Added IDebugSettings.serializeSessionAttributes instead of relying on logger set to debug mode for the session store
Several bug fixes to the Palette component
Property model will now correctly work when chained with a compound model
Fix for firefox not parsing xml-responses after the pages document.domain has been changed to the base-domain. Implemented a workaround for an inconsistency between different servlet containers and a bug in the servlet spec which does not seem to state what should happen with empty valued request parameters. This caused Wicket to have some problems (like a failing required test) with Jetty 6.Implemented anchors on Links. You can either provide a component that is to be used for getting the anchor, or provide an anchor in the href attribute of <a tags.
Portlet (JSR-168) support
Ajax Checkbox now uses onclick instead of onchange which works correctly
Replace GPL licensed diff util with a Apache licensed one
Redirect URLs sometimes were not being encoded for redirects, preventing 'cookie-less' operation (most notably when used with redirectTo). Fixed by always encoding redirects low-down; encoding multiple times has no effect.
Package resources do not have to be pre-registered anymore. When a shared resource is not found, Wicket tries to find a corresponding package resource, and if it finds one, registers it lazily. This fixes quite a few uncomfortable situations, and makes writing custom components easier. Package resources may be blocked by utilizing IPackageResourceGuard (IResourceSettings). By default everything except files with the extension 'html', 'class', 'java', and 'properties' are served. Fixes amongst others bug 1490949. All methods that took Pattern are now deprecated and will be removed in 2.0.
Fixed setting the shared resource path so that it strips any jsession id (or whatever there may be between [path];[whatever][?(optional)] which was a problem when a browser doesn't support cookies
Added rating component to extensions
Added Component.replaceWith(Component) to provide better readability and better context for errors that arise from replace actions
