日系框架之seasar2(Teeda:S2JSF的孪生兄弟)

官方主页：http://teeda.seasar.org/ja/

目前，S2JSF也使用Teeda作为JSF的底层API.

如下图所示建立工程：

所需要的lib列表如下：

commons-collections-3.1.jar
commons-el-1.0.jar
commons-fileupload-1.2.jar
commons-io-1.3.2.jar
commons-lang-2.1.jar

上面的例子包含了一个普通的JSF例子，以及一个使用了Seasar注入的JSF例子。

其实Teeda项目就是在JSF的基础上整合了Seasar的DI功能，框架本身与S2JSF定位基本上是一致的。

如今S2JSF的维护一直处于停滞状态，而Teeda则版本更新很快。可能Teeda才是Seasar团队将来在整合JSF上做出的选择。
