JakartaSever Faces 应用程序设置失败，并出现 java.lang.ClassNotFoundException：com.sun.faces.util.Util

问题描述 投票：0回答：2

我正在建立一个使用 Jakarta 的全新 JavaServer Faces 项目。我遵循 this 作为指导，虽然我理解堆栈跟踪的问题，但我无法理解为什么（新的）Jakarta Faces 实现要求我提供旧的依赖项。

这是我在

您仍然需要包含一些 Jakara Faces 实现，在这种情况下，最简单的一个是 Mojarra，因为您使用的是标准 Jakarta Faces API，该 API 已经需要 Mojarra 实现中的一些类。

您可以在此处查看所有必需的依赖项：https://github.com/eclipse-ee4j/mojarra

如果您想使用 Myfaces，则需要将标准 Jakarta Faces API 替换为他们提供的 Jakata Faces API。

我只是想指出，@ThiagoHenriqueHupner 在 2021 年 12 月 28 日 11:55 发布的解决方案对我来说效果很好。 （我没有投票权）。

下一个链接是 Maven Central Repo 中 Jakarta Faces v4 的 Mojarra 实现

https://mvnrepository.com/artifact/org.glassfish/jakarta.faces

另一种选择是使用 EE 兼容的应用程序服务器：

对于雅加达 EE： https://jakarta.ee/compatibility/

对于 Java EE： https://www.oracle.com/java/technologies/compatibility-jsp.html

如果您确实需要 Myfaces，我可以建议尝试不同版本（向上和向下）的 Myfaces 实现包。

https://mvnrepository.com/artifact/org.apache.myfaces.core/myfaces-bundle

作为最后一个资源，如果您的项目使用 MyFaces 进行编译和执行，请对所有项目进行广泛和深入的测试，可能您不使用“Util”，所以您可能没问题。我知道最后一个不是真正的解决方案，但是嘿，是一个想法。
