使用MyFaces与WASCE/Geronimo时的java.lang.ClassNotFoundException:com.sun.faces.config.ConfigureListener

Question

我正在尝试使用MyFaces v 2.1与WebSphere Application Server Community Edition v3.0.0.1和Eclipse Juno创建一个简单的JSF Web应用程序,但是当我尝试运行该应用程序时,返回以下错误

可能是因为MyFaces jar文件不在类路径中而发生错误,但是由于Eclipse中的构建路径包含所需的jar,我无法弄清楚我出错的地方.我也尝试将jar文件复制到WEB-INF/lib目录中,但无济于事.

下面的屏幕截图显示了项目结构以及库.

我是否需要在Eclipse或WASCE中包含jar文件或者问题出在其他地方？

缺少的课程是Mojarra的一部分,Mojarra实际上是MyFaces的竞争对手.

使用MyFaces时,您根本不需要该类.此异常可能有以下可能的原因:

• <listener>在webapp web.xml或web-fragment.xml任何已部署的JAR中有一个手动定义的条目,/WEB-INF/lib其中引用了这个特定于Mojarra的侦听器类.

• .tld在类路径中有一个松散的Mojarra 文件(非常不可能,谁会提取一个JAR文件并将其松散的内容放在类路径中？).TLD文件自动初始化,并且可以包含<listener>可以触发ServletContextListener实现的自动注册的条目(例如Mojarra ConfigureListener).

只需删除它们就可以解决这些冲突.
