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添加到该项目中。我从Icefaces官方主页下载了文件ICEfaces-2.0.0-Beta2-bin.zip，并按照here中所述的说明进行操作。
我将4个文件icefaces.jar，icepush.jar，icefaces-ace.jar和icefaces-compat.jar从ICEfaces-2.0.0-Beta2-bin/icefaces/lib目录复制到了WEB-INF/lib目录（该文件包含了我所有的jar）。 jsf-api.jar和jsf-impl.jar已经包含在我的项目中，因此没有被复制。
将Web应用程序部署到Tomcat 7服务器时，发生以下错误：
/home/user > ant deploy reload
Buildfile: build.xml

[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

这是来自
catalina.log的，我认为这可能很有趣：INFO: JSF1048: PostConstruct/PreDestroy annotations present. ManagedBeans methods marked with these annotations will have said annotations processed.

我不明白如何复制这4个文件会产生此错误。我什么都没做您能帮我吗？
最佳答案
像往常一样，异常stacktrace的caused by部分讲述了问题的根本原因。您的情况如下：
Caused by: java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory
这是不言自明的。运行时类路径中缺少提到的类。将
commons-logging.jar添加到/WEB-INF/lib，此特定问题应解决。如果您还没有其他地方（也许在IceFaces下载中？），则可以在http://commons.apache.org/logging处获得它。
