JSF 2.0 + Icefaces 2.0.0 Beta2和Tomcat 7失败

Question

我有一个在Tomcat 7.0.4服务器上工作的现有JSF 2.0项目。我正在尝试将Icefaces 2.0.0 Beta2添加到此项目中。我从Icefaces官方主页下载了文件ICEfaces-2.0.0-Beta2-bin.zip，并按照说明here。

我复制了4个文件icefaces.jar，icepush.jar，icefaces-ace.jar和icefaces-compat.jar从ICEfaces-2.0.0-Beta2-bin/icefaces/lib目录到WEB-INF/lib目录（即我包括我所有的罐子的一个）。 jsf-api.jar和jsf-impl.jar已经包含在我的项目中，因此不会被复制。

当我部署web应用程序到Tomcat 7服务器，出现下列错误：

/home/user > ant deploy reload 

Buildfile: build.xml 

build: 

deploy: 

reload: 
    [reload] FAIL - Encountered exception java.lang.IllegalStateException: Container org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/wtree-www] has not been started 

BUILD FAILED 
FAIL - Encountered exception java.lang.IllegalStateException: Container org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/wtree-www] has not been started 

Total time: 0 seconds 

这是从catalina.log，我认为这可能是intresting：

我不了解如何复制4个文件可能会产生此错误。我没有做任何事你能帮我吗？

像往常一样，异常堆栈跟踪的caused by部分讲述了问题的根本原因。你的情况如下：

Caused by: java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory 

这是很自我解释。运行时类路径中缺少上述类。将commons-logging.jar添加到/WEB-INF/lib，这个问题应该解决。如果你还没有在其他地方（在IceFaces下载也许？），那么你可以在http://commons.apache.org/logging。
