部署Primefaces-Extensions示例时出错,为什么?

mey*_*uel 4 primefaces primefaces-extensions

部署时出错:加载应用程序时出现异常:java.lang.IllegalStateException:ContainerBase.addChild:start:org.apache.catalina.LifecycleException:java.lang.RuntimeException:com.sun.faces.config.ConfigurationException:java.lang. ClassNotFoundException:org.apache.commons.lang3.StringEscapeUtils尚未部署模块.

这是我的代码:

正如在https://github.com/primefaces-extensions/primefaces-extensions.github.com/wiki/Getting-Started上的primefaces扩展项目入门中所述,您需要在项目中添加"Apache Commons Lang3".

如果它不在类路径中,请将Apache Commons Lang3添加到您的项目中.

您可以从http://commons.apache.org/proper/commons-lang/下载该库.
