Question

我正在使用RichFaces和jsf 2.但是当我转移到facelets时丰富的组件对我不起作用。我正在使用

richfaces-api-3.3.4.Final.jar，
RichFaces的-IMPL-jsf2-3.3.4.Final.jar，
RichFaces的-UI-3.3.4.Final.jar。
tomcat版本是7.0.23
netbeans 7.3.1

我在web.xml中配置了以下详细信息

当我在clean之后部署并构建它时会显示以下错误。

有人能发现我在这里犯了什么错误吗？

Answer 1

RichFaces 3.x和JSF 2工作正常。我使用的是JSF 2.2和RichFaces 3.3.4.Final。

您需要禁用内置的JSF 2 facelets并添加对旧jsf-facelets 1.1.15的依赖（根据https://developer.jboss.org/wiki/RichFaces333andJSF20）。

但请注意，Mojarra在根据规范查找DISABLE_FACELET_JSF_VIEWHANDLER而不是javax.faces.DISABLE_FACELET_JSF_VIEWHANDLER时会有bug。

RichFaces和facelets组合不起作用
