无法在JSF应用程序中分析文档faces-config.xml

我正在开发一个JSF web应用程序。我将JSF2.2与ApacheTomcat8.0.27.0结合使用。 当我按下clean&build时，它工作正常，但当我尝试运行我的应用程序时，会出现以下异常：

     com.sun.faces.config.ConfigurationException: java.util.concurrent.ExecutionException: com.sun.faces.config.ConfigurationException: Unable to parse document 'file:/C:/Users/axeli/Desktop/SeminarioPagina/build/web/WEB-INF/faces-config.xml': null

这些是我现在正在使用的库：

com.sun.faces.config.ConfigManager$ParseTask.getDocument上的java.lang.NullPointerException（ConfigManager.java:1172）

这通常只在

faces config.XML

本身出现XML语法错误，并且XML解析器（错误地）没有抛出异常，只是返回了

null

时发生。请仔细注意文档的XML格式良好性。即，每个

必须有一个匹配的

，每个

“

必须有一个匹配的

”

，等等

---

如果您使用的是IDE，请确保它具有必要的JSF/JavaEE插件，这些插件通常负责XML验证。或者，如果已经有，请注意IDE中的错误/警告。如果您不确定，请在某些情况下复制粘贴

faces config.xml

，例如。

由于某些原因，如果faces config的version属性（可能还有命名空间defs）太高，应用程序服务器无法处理，也会发生这种情况

我在一个试图使用JSF2.2的古老的Glassfish3上发现了这一点，而它只对2.0或2.1感到满意

希望这能帮助别人少浪费时间在这上面

对于决定返回

null

作为有用消息的人：。。。事实上，我没什么好说的

---

---

我知道应该这样做™ 有可能升级Glassfish 3的库以支持JSF 2.2，但是还没有完成。

请添加faces.config.xml文件。正如你所说，我的

faces config.xml

中有一个错误。谢谢你@BalusC
