当我运行我的项目时，出现以下错误。 而且我也不知道上面的配置和罐子是否正确。

假装不在乎 2025-01-02 21:45:07

将faces-config.xml 中的视图处理程序设置更改为

<application>
  <view-handler>org.ajax4jsf.application.AjaxViewHandler</view-handler>
</application>

Change the view handler setting in faces-config.xml to

<application>
  <view-handler>org.ajax4jsf.application.AjaxViewHandler</view-handler>
</application>
