jsf-2 - RichFaces4 启动失败，出现 java.lang.IllegalArgumentException : duplicate key: class javax. faces.convert.DoubleConverter

标签 jsf-2 richfaces

对于没有 Maven 的 RichFaces4，这似乎不是一项简单的任务，我下载了 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 .

我工作的环境是 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。我添加了一些与以下错误相关的 jar，但我收到另一个转换器的另一个重复 key 错误，

另一方面:我还必须从 tomcat 中删除 tomohawk，因为我正在使用 myfaces。请帮忙。

最佳答案

如果您还在类路径中包含 RichFaces 源代码 JAR 文件，就会发生这种情况。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。您应该从 /WEB-INF/lib 中删除它们，并在必要时将它们放在其他不会出现在 webapp 的运行时类路径中的地方。

罪魁祸首是 csv.xml 文件，它位于 richfaces-components-ui-4.0.0 的 /META-INF 文件夹中。 Final.jar 和 richfaces-components-ui-4.0.0.Final-source.jar 文件。该文件定义了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了两次，它被读取了两次，导致了这个重复键异常。

与具体问题无关，因为您使用的是 MyFaces 而删除 Tomahawk 是没有争议的。 MyFaces JSF 实现不包含与 Tomahawk 相同的组件。它只是另一个 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 实现之上提供更多增强组件，并且可以在每个 JSF 实现之上使用。
