Question

我正在开发一个JSF Web应用程序。我将JSF 2.2与Apache Tomcat 8.0.27.0一起使用。当我按下清洁＆amp;构建它工作正常，但当我尝试运行我的应用程序时，我得到了这个例外：

     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：

Answer 1

com.sun.faces.config.ConfigManager中的java.lang.NullPointerException $ 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）没有抛出异常但只返回null时。请仔细注意文档的XML格式。即每个<element>必须有匹配的</element>，并且每个"都必须匹配"等。

如果您正在使用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。或者如果您已经拥有，请注意IDE中的错误/警告。如果您不确定，请在某些online XML validation tool中复制faces-config.xml，例如http://www.xmlvalidation.com。

Answer 2

由于某些原因，如果faces-config的version属性（可能还有名称空间defs）过高而应用程序服务器无法处理，也会发生这种情况。

我以某种方式在试图使用JSF 2.2的古老Glassfish 3上发现了这一点，而它只对2.0或2.1满意。

希望这可以帮助某人减少时间。

对于决定返回null作为有用信息的人：...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，但是并没有这样做。

无法在JSF应用程序中解析文档faces-config.xml
