对于没有Maven的RichFaces4，这似乎不是一个简单的任务，我下载myfaces-2.0.9 jar和richfaces 4.0.0并添加了sac-1.3.jar，guava-r08.jar和cssparser-0.9.5.jar
我正在使用的环境是Tomcat 6.0，但是当我运行tomcat时，我无法设置一个简单的基于richfaces4的Web应用程序我遇到了不同的问题。我添加了几个与下面的错误相关的jar，但我得到了另一个转换器的另一个重复键错误
另一方面说明：当我使用myfaces时，我还必须从tomcat中删除tomohawk。请帮忙。

答案 0 :(得分：7)
如果您还在类路径中包含RichFaces 源代码 JAR文件，则会发生这种情况。它们不属于webapp的运行时类路径。它是文件名以-source.jar结尾的文件名。你应该从/WEB-INF/lib 删除，并在必要时将它们放在其他不在webapp的运行时类路径中的地方。
罪魁祸首是csv.xml文件，该文件存在于/META-INF和richfaces-components-ui-4.0.0.Final.jar文件的richfaces-components-ui-4.0.0.Final-source.jar文件夹中。该文件定义标准转换器和验证器。但是，因为该文件现在在类路径中出现两次，所以它被读取了两次，导致这个重复的键异常。
无关到具体问题，因为你正在使用MyFaces而删除Tomahawk是一个非参数。 MyFaces JSF实现不包含与Tomahawk相同的组件。这只是另一个JSF实现，技术上是Mojarra的竞争对手。 Tomahawk是一个独立的组件库，它在标准JSF实现之上提供了更多增强的组件，并且可以在每个JSF实现之上使用。
