ICEfaces是一个基于Ajax的JSF开发框架。ICEfaces原本是一个商业产品，现已开源基于Mozilla Public License发布。它提供一整套完整的Java EE应用程序开发组件，能够帮助开发人员用纯Java(not JavaScript)快速开发瘦客户端胖互联网应用程序(Rich Internet Applications:RIA)。可通过其提供的一个在线Demo体验一下ICEfaces的强大组件。
ICEFaces是JSF组件的一个类库，并在此基础上添加了对AJAX特有的处理方法：在Server端绑定了DOM，并且通过AJAX的推技术将 Server端上的改变传递给client。这就意味着Server端在与各种各样的后端数据服务交互后，获得表示层应如何变化的信息，利用推技术，立即可以异步发送动态数据给用户界面，而不需用户的介入。
发行说明如下：
New Supported Platforms
Support for the following additional platforms is added in this release: Google Chrome 10 Mozilla Firefox 4.0 Microsoft Internet Explorer 9 (IE 9) Oracle Glassfish 3.1 (final) JBoss 6.0 (final) Liferay Portal 5.2.3
Core Framework
Lazy Window Scope Initialization
Management of Window Scope requires HTTP messages to be sent to the server whenever browser navigation or window closing events occur. To avoid unnecessary network traffic, Window Scope initialization has been optimized to only perform Window Scope related HTTP transactions when Window Scope is being used by the application. Single-Submit Several improvements have been made to SingleSubmit to resolve issues with unnecessary double-submits occurring in specific circumstances. JavaScript Bridge Due to a bug in Mojarra, JSF full-page DOM updates performed via Ajax do not properly execute JavaScript included in the <HEAD> region of the page on some browsers (IEs, Firefox), resulting is unpredictable and hard-to-trace failures. A work-around for this issue has been included in this release. HTTP errors are now handled and reported by the ICEfaces bridge. There is an associated new ice.onNetworkError(callback) JavaScript Client API in support of this. It is now possible to disable the default ICEfaces error popup panels. By default, ICEfaces will report various connection or application errors in the form of popup dialog panels in the browser window. Using one of the techniques below, it is now possible to disable the default error dialogs, which is useful if you are implementing your own error reporting strategy, etc. A new ice.disableDefaultErrorPopups JavaScript Client API is
available for dynamically disabling the error popups on the client using JavaScript. The new configuration parameter "org.icefaces.disableDefaultErrorPopups" can be specified in the web.xml file to disable the default error popups. See the Configuration topic for details. Several omissions and errors have been corrected in the JavaScript Client API topic in the ICEfaces 2 Documentation Wiki.
ICEfaces Components
The JavaScript files used by the ICEfaces Components have been optimized to reduce their sizes, resulting in a 50% size savings vs. 2.0.0 (approx.
250KB). ice:dataPaginator A layout bug related to using "vertical" alignment has been fixed. ice:inputRichText Now supports the "partialSubmit" attribute. ice:outputResource Now supports the "disabled" attribute. ice:panelPopup Several issues with modal ice:panelPopups in various browsers and use-cases have been resolved. ice:selectOneMenu This component can now accept an array of Objects as input to create the list.
ICEfaces Advanced Components
Reduced Static JavaScript Footprint The Advanced Components now leverage the YUI bootstrap loader which greatly reduces the number and size of the JavaScript files that must loaded when initially visiting the page. The net result is that pages using the Advanced Components now load dramatically faster and overall response time when navigating between pages is substantially improved. ace:fileEntry New support for stream-based processing of uploaded files, roughly analogous to the old ice:inputFile's outputStream property. Using this mode of operation, when files are uploaded they are not automatically written to the server file-system, but will instead be processed by the new FileEntryCallback interface, allowing for in-memory processing of the file. Typical use-cases for this
functionality are when the file may be stored in a database, needs to be virus scanned before being saved on the server, etc. The previously selected file/path information is now automatically cleared upon the successful completion of an upload. ace:slider Now supports displa
ying range labels on slider for min, median, and max values via the new "showLabels" attribute. All ACE input components now support the "disabled" attribute and associated skin style-classes and pre
defined skin styles.
