Question

我要升级现有的项目JSF2.I在SUN RI和myfaces的组合中遇到了很多问题，所以我从classpath中删除了所有的SUN RI，现在facelets和myfaces的组合给出了问题。我想知道我们是否消除facelets并使用apache myfaces应该是taglib命名空间？我得到这个错误

如果有人参与JSF2升级，请帮助我。

Answer 1

我目前正在使用MyFaces 2.0.2开发JSF 2 / Facelets项目。我只有myfaces-impl和myfaces-api JAR以及类Compath中的Apache Commons。

My Facelets名称空间声明为xmlns:ui="http://java.sun.com/jsf/facelets"。

JSF2升级到现有项目
