Question

我的应用程序使用JSF2和Richfaces 3.3.3，mojarra 2.0.2在Glassfish 3.1上工作得很好，但每当我将其移植到Tomcat 7.0.10上时，每次都会遇到这样或那样的问题。它从检测jsf_core.tld失败开始，然后是一些JSF呈现问题，最后是这个问题。最后，我发现了一些我在这里提到的，并且我找不到解决的方法。

Answer 1

在运行时类路径中有RichFaces impl文件，但没有RichFaces API文件。

堆栈跟踪就是这方面的证据：

Caused by: java.lang.NoClassDefFoundError: org/ajax4jsf/resource/InternetResourceBuilder
    at org.ajax4jsf.renderkit.ChameleonRenderKitFactory.<init>(ChameleonRenderKitFactory.java:62)

at org.ajax4jsf.renderkit.ChameleonRenderKitFactory行表明这个特定的类已被成功加载和执行(否则它根本不会在堆栈跟踪中显示为at xxx )。此类是RichFaces impl JAR文件的一部分。InternetResourceBuilder反过来又是RichFaces API JAR文件的一部分。这显然是运行时类路径中缺少的。至少，这正是异常告诉我们的。

Answer 2

从异常看，似乎找不到Richfaces。将jar放在类路径中(对于Tomcat WEB-INF/lib或WEB-INF/classes)，然后重试。
