Flex要开源啦～

http://labs.adobe.com/wiki/index.php/Flex:Open_Source

Adobe is announcing plans to open source Flex under the Mozilla Public License (MPL). This includes not only the source to the ActionScript components from the Flex SDK, which have been available in source code form with the SDK since Flex 2 was released, but also includes the Java source code for the ActionScript and MXML compilers, the ActionScript debugger and the core ActionScript libraries from the SDK. The Flex SDK includes all of the components needed to create Flex applications that run in any browser - on Mac OS X, Windows, and Linux and on now on the desktop using “Apollo”.

Developers can use the Flex SDK to freely develop and deploy Flex applications using either Adobe Flex Builder or an IDE of their choice.

[edit]License
The source code for the Flex SDK will be available under the Mozilla Public License (MPL). The MPL will allow full and free access to the source code, allowing developers to download, extend, and contribute to the source code for the Flex compiler and framework classes. The Flex SDK will also be available under a commercial Adobe license. Offering a choice of licenses serves the needs of enterprise Flex customers and partners.

[edit]Schedule
The source code for the Flex framework is already available within the free distribution of the current Flex 2 SDK. By this summer, Adobe plans to put in place most of the infrastructure (public bug database and public daily builds) required to run the Flex SDK as an open source project. We expect to complete the transition to a fully open source project (source code for the compiler, infrastructure for community contributions, etc.) by the end of 2007.

[edit]Currently Supported Platforms
Windows XP, Server 2003, or Windows Vista Professional/Ultimate with Java 1.4 (Sun, IBM, or BEA) or 1.5 (Sun)
Mac OS X 10.4.x, Java 1.5 (as shipped from Apple) on PowerPC and Intel processor
Redhat Enterprise Linux 3 or 4, Suse 10, Java 1.4 (Sun, IBM, or BEA) or 1.5 (Sun)
Solaris 9, 10, Java 1.4 or 1.5 (Sun) Compilers only

[edit]How can I ask more questions?

太棒了！

很高兴听到这个消息！哈哈哈。。。

dlee：这下可以抛掉AJAX了吧：）

好啊！

大家有什么Flex心得，分享分享吧！

不过我早已经投奔.net阵型，而flex对.net支持....
不过，还有silverlight，这个东东将会支持c#的．
感觉adobe有点针对ms 的mix 07，因为mix 07的主要内容是silverlight．

竞争是好事，Adobe这个开源，也是给WPF和Sliverlight逼的。

open source的只是Flex SDK，没包括Builder和Data Services。

好消息！

可以不用Data Services
生成swf文件就行了。

但是基于Flash的技术还是有一个最大的缺陷，那就是对于搜索引擎不友好。WPF所基于的XAML是纯文本的，对于引擎搜索要友好的多。

对于搜索引擎友好，是大部分Internet应用的一个基本的需求。对于Intranet应用，这个需求就不需要考虑了。所以只要能够解决好Flash的性能问题，基于Flash UI开发企业应用，也是一种很好的选择。

Flash UI主要的应用场合是面向Intranet的软件产品，我不倾向于在Internet应用中使用Flash UI。
