java.lang.ClassNotFoundException : com. sun.faces.config.ConfigureListener 将 MyFaces 与 WASCE/Geronimo 一起使用时

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

可能发生错误是因为 MyFaces jar 文件不在类路径中，但是由于 Eclipse 中的构建路径包含所需的 jar，我无法弄清楚我哪里出错了。我也试过将jar文件复制到WEB-INF/lib目录下，但没有成功。

下面的屏幕截图显示了项目结构以及库。

我需要在 Eclipse 或 WASCE 中做些什么来包含 jar 文件还是问题出在其他地方？

缺少的类是 Mojarra 的一部分，实际上是MyFaces的竞争对手.

在使用 MyFaces 时，您根本不需要该类。此异常可能有以下原因:

• 有一个手动定义的<listener>进入 webapp 的 web.xml或 web-fragment.xml /WEB-INF/lib 中任何已部署的 JAR它引用了这个特定于 Mojarra 的监听器类。

• 某处有松散的 Mojarra .tld类路径中的文件(不太可能，谁会提取 JAR 文件并将其松散的内容放入类路径中？)。 TLD 文件被自动初始化并且可以包含 <listener>可以触发 ServletContextListener 自动注册的条目实现(例如 Mojarra ConfigureListener)。

这些冲突可以通过删除它来解决。
