我正在开发一个目前使用JSF 1.2的项目和没有RichFaces的独立Ajax4JSF库。我们正在迁移到JSF 2.2，我们希望将所有<a4j:xxx>代码替换为标准等效代码，例如<f:ajax>。因此，我们希望摆脱对第三方库Ajax4JSF的依赖。
作为一步，我从web.xml
<filter-mapping>
<filter-name>ajax4jsf</filter-name>
<servlet-name>faces</servlet-name>
<dispatcher>REQUEST</dispatcher>
<dispatcher>FORWARD</dispatcher>
</filter-mapping>
然而，它引起了以下异常：

这是如何引起的，我该如何解决？安装RichFaces 4.x不是一个选项，我们只想完全摆脱Ajax4JSF。
