Question

我正在尝试升级到JSF2和Spring 3.0.5，当我部署到Tomcat时，我收到以下错误。

任何帮助表示感谢。

您没有提供太多信息，但您的配置中必定有问题。提示：

错误的Spring或JSF版本或某些库卡在Tomcat lib中。您使用任何类型的依赖管理吗？你的spring-web-xxx.jar的确切版本是什么？你使用什么JSF实现？那个版本是什么？

您的任何xml配置文件中的错误的schemalocation / version。异常表明问题在于faces配置。它应该是这样的：

<faces-config 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"
          version="2.0">
<application>
    <el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver>
</application>

您可以找到一些示例here和here。如果您无法解决问题，请发布一些配置文件。（appcontext.xml，web.xml，faces-config.xml）

使用SpringBeanFacesELResolver的javax.faces.el.VariableResolver Classcast异常
