JSF异常部署到类，标记名为inputFile null handler- FireFly

Question

我正在尝试学习JSF，但在部署任何项目时都遇到了问题。我已经安装了以下软件：

Eclipse Kepler 2

用于eclipse的JBoss工具

WildFly 8

Maven 3.2.1

Java JDK 8

mojarra 2.2.6

我在创建JSF项目并下载示例项目时遇到了这个问题。当我在eclipse中将项目部署到WildFly时，它抛出了一个异常：

JBAS014777:   Services which failed to start: service jboss.undertow.deployment.default-server.default-host./Test: org.jboss.msc.service.StartException in service jboss.undertow.deployment.default-server.default-host./Test: Failed to start service

WildFly的deployment文件夹中的Test.war.failed文件包含以下内容：

"{\"JBAS014671: Failed services\" => {\"jboss.undertow.deployment.default-server.default-host./Test\" => \"org.jboss.msc.service.StartException in service jboss.undertow.deployment.default-server.default-host./Test: Failed to start service
Caused by: java.lang.RuntimeException: java.lang.RuntimeException: com.sun.faces.config.ConfigurationException: The tag named inputFile from namespace http://xmlns.jcp.org/jsf/html has a null handler-class defined
Caused by: java.lang.RuntimeException: com.sun.faces.config.ConfigurationException: The tag named inputFile from namespace http://xmlns.jcp.org/jsf/html has a null handler-class defined
Caused by: com.sun.faces.config.ConfigurationException: The tag named inputFile from namespace http://xmlns.jcp.org/jsf/html has a null handler-class defined\"}}"

此外，我不知道这是否相关，但当我在eclipse中打开faces-config.xml文件时，它不会显示包含许多web示例所显示的所有选项卡的页面。它只有Diagram、Tree和Source的选项卡。这是因为示例是JSF 2.0，而我使用的是JSF 2.2.6吗？

Answer 1

请从依赖项中删除Mojarra。WildFly已经发布了一个JSF实现，如果你在你的应用中部署一个，你就会遇到这样的问题。

用JSF 2.1而不是2.2重新创建动态web项目为我解决了这个问题……然后再一次出现相同的错误，并按如下方式更新web.xml。
