从facelets 1.x迁移到facelets 2.0 [英] migrating to facelets 2.0 from facelets 1.x
问题描述
我正在使用JSF 2.0构建Web应用程序，并且在我的WEB-INF> lib文件夹中有一个jaf-facelets.1.1.10 jar，所以现在我尝试将其删除，以便可以使用内置的int facelets 2.0我正在阅读 balusC回答的这个问题并且我已经做到了，除了说我需要用ViewHandlerWrapper替换FaceletViewHandler的那一部分.为此，我看到了这个问题，但是我的项目中没有任何faceletViewhandler类.
I'm building a web App using JSF 2.0 and had a jaf-facelets.1.1.10 jar in my WEB-INF > lib folder, so now I'm trying to remove that so I can use the built int facelets 2.0 I was reading through this Question which balusC answered and I've done that, except teh part where it saysI need to replace FaceletViewHandler by ViewHandlerWrapper. for that I saw this question, but I don't have any faceletViewhandler classes in my project.
到目前为止，我的webxml看起来像这样(请检查我什么都没错过，或者我引用的是我不应该错过的东西:
as of now, my webxml looks like this ( please check taht I didn't miss anything, or I'm referencing something I shouldn't:

正如您所看到的，我删除了
And as you can see, I have quite a few faces-configs I removed the
<application>
<view-handler>com.sun.facelets.FaceletViewHandler</view-handler>
</application>
现在看起来像这样(我知道某些功能我不需要导航，但是将其保持原样真的有害吗?):
And now it looks like this ( I know some features I don't need like the navigation, but does it really hurt to keep it taht way?):
<?xml version="1.0" encoding="UTF-8"?>
<faces-config

</faces-config>
进行一些更改并像这样保留之后，我在tomcatv7上运行该项目，并得到以下错误:
after doing some changes and leaving it like that, I run the project on tomcatv7 and get this error:
java.lang.NoClassDefFoundError: javax/servlet/jsp/jstl/core/Config

看起来像我的文件一样会出现错误吗?因为我所做的只是删除了jar-facelets.1.1.10.jar，现在我遇到了这个错误.但是App可以正常工作b4我删除了facelets jar，那么这两个jar之间是什么关系?
Does that look like an error I would get for having my files like this? because all I did was remove the jar-facelets.1.1.10.jar and now I'm getting this Error. But teh App works fine b4 I remove the facelets jar, so what is the relationship between these two jars??
我尝试添加jstl.jar，但这不起作用，它只是向我显示了这一点:
I tried adding the jstl.jar but that doesn't work, it just shows me this:
推荐答案
The error suggest include jstl-1.2.jar available here in the same folder where your jsf jars are.
不需要facelets 2.0 jar，因为JSF 2.0将facelets作为其默认的视图声明语言(VDL)，现在它已捆绑在jsf jar中(对于MyFaces和Mojarra)
There is no need for facelets 2.0 jar, because JSF 2.0 adopted facelets as its default View Declaration Language (VDL), and now it is bundled inside jsf jars (for both MyFaces and Mojarra)
