JSF 2.3启动中未定义的组件类型javax.faces.ViewRoot [英] Undefined component type javax.faces.ViewRoot in JSF 2.3 startup

问题描述

这是我在此处找到的早期问题的新转折. .

我正在从MyFaces 2.1升级到2.3.5，并且从PrimeFaces 6.1升级到7.这还包括从托管bean迁移到CDI.此时，服务器启动，似乎MyFaces，PrimeFaces和CDI正在初始化.但是，当我尝试加载我的第一页时，出现"Undefined component type javax.faces.ViewRoot".请注意，这是组件类型"而不是类.

I'm upgrading from MyFaces 2.1 to 2.3.5, and from PrimeFaces 6.1 to 7. This has also included migrating from managed beans to CDI. At this point, the server starts up and it appears that MyFaces, PrimeFaces, and CDI are being initialized. However, when I attempt to load my first page I get "Undefined component type javax.faces.ViewRoot". Note, this is a "component type" not a class.

通过进入MyFaces代码，我可以看到组件类映射正在使用许多组件进行初始化，但与ViewRoot相似.我很犹豫尝试手动注册UIViewRoot，因为在早期版本中这不是必需的，而且我还没有看到有必要提及这种事情.

Tracing into the MyFaces code, I can see that the component class map is being initialized with lots of components, but nothing similar to ViewRoot. I'm hesitant to try manually registering UIViewRoot since this wasn't necessary with the earlier versions and I haven't seen any mention of something like this being necessary.

有人可以暗示我可能在做错什么吗?

Can anyone suggest what I may be doing wrong?

我在下面包括了相关的配置和日志文件(节略).

I've included the relevant configuration and log files (abridged) below.

[对于@tandraschko，他对我最近在这里的努力非常有帮助，因此我正在使用不捆绑的MyFaces api&展示库.正如您所建议的那样，我将创建一个简化的项目，以查看是否可以更小规模地重现或确定问题.]

[And for @tandraschko who's been so helpful with my recent struggles here, I am using the non-bundled MyFaces api & impl libraries. And as you've suggested, I'm going to create a stripped-down project to see if I can reproduce or identify the issue on a smaller scale.]

推荐答案

最后！解决了.不过，答案显示出我的无知:

Finally! Solved it. Though, the answer shows my ignorance:

不要将您的faces-config.xml文件重命名为 standard-faces-config.xml

Don't rename your faces-config.xml file to standard-faces-config.xml

以前，我在设置Maven和Eclipse来正确构建包含我的所有库(包括JSF)并由我的主应用程序项目引用的公共项目时遇到麻烦.有时，主应用程序的faces-config.xml似乎正在覆盖通用应用程序的faces-config.xml.我偶然发现了对standard-faces-config.xml的引用.因此，我将常见的faces-config.xml重命名为standard-faces-config.xml，这似乎可行.我以为那是处理多项目应用程序的方法.

Earlier, I had trouble setting up Maven and Eclipse to properly build a common project containing all my libraries (including JSF) and referenced by my main application project. At one point it seemed that the main application's faces-config.xml was overwriting the common application's faces-config.xml. I stumbled across references to standard-faces-config.xml. So I'd renamed the common faces-config.xml to standard-faces-config.xml, which seemed to work. I'd assumed that was how to handle multi-project applications.

更糟糕的是，一旦我使Maven和Eclipse正常运行，我就怀疑这种变化.但是恢复文件名似乎没有任何作用.这已经成为我第二个来之不易的课:

To make matters worse, I'd suspected this change once I got Maven and Eclipse working. But reverting the filename didn't seem to do anything. This has become my second hard-earned lesson:

使用Maven和Eclipse，请确保您确实在重建和重新部署项目

With Maven and Eclipse, make sure you're really rebuilding and redeploying your projects

现在很多次我进行了更改并重新启动，只是意识到我的更改不包括在内.

So many times now I've made changes and relaunched, only to realize my changes weren't included.

非常感谢所有回答的人，尤其是@tandraschko！

Many thanks to everyone who responded, especially @tandraschko!
