也许您的 web.xml 包含错字？全能面 1.8.1

Question

我正在使用 Omnifaces 1.8.1，我在启动时遇到了这个错误 Tomcat 7

WebXml failed to initialize. Perhaps your web.xml contains a typo? java.lang.ClassNotFoundException: at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Unknown Source) at org.omnifaces.config.WebXml.parseErrorPageLocations(WebXml.java:434) at org.omnifaces.config.WebXml.init(WebXml.java:147) at org.omnifaces.facesviews.FacesViewsInitializerListener.contextInitialized(FacesViewsInitializerListener.java:63) at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:5016) at org.apache.catalina.core.StandardContext.startInternal(StandardContext.java:5524) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:150) at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1575) at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1565) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source)

Answer 1

ClassNotFoundException 表示您的 xml 包含无法在 CLASSPATH 中找到的 class：要么是打字错误 - 要么 class 丢失，因为某些 jar 丢失或错误地点

org.omnifaces.filter.CharacterEncodingFilter ?

Answer 2

at org.omnifaces.config.WebXml.parseErrorPageLocations(WebXml.java:434)

WebXml 是 omnifaces 中的实用程序 class，它为常用的 web.xml 元素提供方法。

堆栈跟踪中的上述行表明您配置了一个异常 class，它在 classspath 中不存在。

请 post 您在 web.xml

中的 <error-page/> 标签片段
