web.xml 中的异常类型不起作用[重复]

Question

如果我在我的 saas 应用程序中抛出异常，则不会显示 web.xml 中配置的错误页面。但是，如果我使用了错误的 url，则会显示错误页面。所以带有错误代码的配置是有效的，但带有异常类型的配置不是。要在 web.xml 中运行异常类型的配置，我需要进行哪些更改？

我正在使用例如JBoss 7.1 和 primefaces 5.0。和 jsf 2.0。

我的web.xml

<error-page>
     <error-code>404</error-code>
    <location>/pages/public/generic-error.xhtml</location>
</error-page>

<error-page>
    <exception-type>java.lang.Throwable</exception-type>
    <location>/pages/public/generic-error.xhtml</location>
</error-page>

如果我在代码中抛出NullPointerException，以下是来自控制台的堆栈跟踪：

这个异常是在 JSF 中引起的。使用 JSF 异常处理工厂，请参阅 JSF 2 Global exception handling, navigation to error page not happening
