无法在 JSF 应用程序中解析文档面孔-config.xml
Unable to parse document faces-config.xml in JSF application
我正在开发一个 JSF 网络应用程序。我将 JSF 2.2 与 Apache Tomcat 8.0.27.0 一起使用。
当我按下 clean & build 时它工作正常，但是当我尝试 运行 我的应用程序时我得到这个异常：

这些是我现在正在使用的库：
java.lang.NullPointerException at com.sun.faces.config.ConfigManager$ParseTask.getDocument(ConfigManager.java:1172)
这通常只发生在 faces-config.xml 本身存在 XML 语法错误并且 XML 解析器（错误地）没有抛出异常而只是返回 null.请仔细注意文档的 XML 格式是否正确。 IE。每个 <element> 必须有匹配的 </element>，每个 " 必须有匹配的 "，等等
如果您使用的是 IDE，请确保它具有必要的 JSF/Java EE 插件，这些插件通常负责 XML 验证。或者，如果您已经有，请注意 IDE 中的 errors/warnings。如果您不确定，请在某些 online XML validation tool, such as http://www.xmlvalidation.com.
中复制粘贴 faces-config.xml
出于某种原因，如果 faces-config 的版本属性（可能还有名称空间定义）对于应用程序服务器来说太高而无法处理，也会发生这种情况。
我以某种方式在尝试使用 JSF 2.2 的古老 Glassfish 3 上发现了这个，而它只对 2.0 或 2.1 感到满意。
希望这可以帮助人们减少在这上面浪费的时间。
对于决定 return null 的任何人，作为一条有用的信息：......实际上，我没什么好说的。
我知道应该™可以升级 Glassfish 3 的库以支持 JSF 2.2，但是没有这样做。

28-Feb-2016 18:00:21.358 SEVERE [http-nio-8084-exec-10] javax.faces.FactoryFinder.releaseFactories Unable to call @PreDestroy annotated methods because no InjectionProvider can be found. Does this container implement the Mojarra Injection SPI?
28-Feb-2016 18:00:21.390 INFO [http-nio-8084-exec-10] org.apache.catalina.startup.HostConfig.deployDescriptor Deployment of configuration descriptor C:\Users\axeli\AppData\Roaming\NetBeans.1\apache-tomcat-8.0.27.0_base\conf\Catalina\localhost\ROOT.xml has finished in 1.512 ms
这些是我现在正在使用的库：
java.lang.NullPointerException at com.sun.faces.config.ConfigManager$ParseTask.getDocument(ConfigManager.java:1172)
这通常只发生在 faces-config.xml 本身存在 XML 语法错误并且 XML 解析器（错误地）没有抛出异常而只是返回 null.请仔细注意文档的 XML 格式是否正确。 IE。每个 <element> 必须有匹配的 </element>，每个 " 必须有匹配的 "，等等
如果您使用的是 IDE，请确保它具有必要的 JSF/Java EE 插件，这些插件通常负责 XML 验证。或者，如果您已经有，请注意 IDE 中的 errors/warnings。如果您不确定，请在某些 online XML validation tool, such as http://www.xmlvalidation.com.
中复制粘贴faces-config.xml
出于某种原因，如果 faces-config 的版本属性（可能还有名称空间定义）对于应用程序服务器来说太高而无法处理，也会发生这种情况。
我以某种方式在尝试使用 JSF 2.2 的古老 Glassfish 3 上发现了这个，而它只对 2.0 或 2.1 感到满意。
希望这可以帮助人们减少在这上面浪费的时间。
对于决定 return null 的任何人，作为一条有用的信息：......实际上，我没什么好说的。
我知道应该™可以升级 Glassfish 3 的库以支持 JSF 2.2，但是没有这样做。
