JSF 2.0 + Icefaces 2.0.0 Beta2 和 Tomcat 7 失败

Question

我有一个在 Tomcat 7.0.4 服务器上运行的现有 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 中描述的说明进行操作。 .

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(我包含所有我的 jar )。 jsf-api.jar 和 jsf-impl.jar 已经包含在我的项目中，所以没有复制它们。

当我将 webapp 部署到 Tomcat 7 服务器时，出现以下错误:

/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

这是来自 catalina.log，我认为这可能很有趣:

我不明白复制这 4 个文件怎么会产生这个错误。我没有做任何其他事情你能帮帮我吗？

像往常一样，异常堆栈跟踪的 caused by 部分说明了问题的根本原因。在你的情况下是这样的:

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 并且这个特定问题应该解决。如果您还没有在其他地方拥有它(也许在 IceFaces 下载中？)，那么您可以在 http://commons.apache.org/logging 获得它。 .
