Question

我正在尝试将我的应用从jsf 1.2迁移到2.1。我写了一个样本facelet页面并尝试访问它。获得以下异常。不确定导致此问题的原因。如果仅执行此页面（通过删除与我的项目相关的所有代码和库，此页面正确呈现）。任何可能导致此问题的帮助都会非常有用。

Answer 1

此问题与faces-config.xml有关。标题应该是。

<faces-config version="2.0"
   xmlns="http://java.sun.com/xml/ns/javaee"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="
      http://java.sun.com/xml/ns/javaee
      http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd">

Answer 2

在头元素中包含此标记，如下所示：

<h:head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</h:head>
