各种JSTL库之间有什么区别，使用哪些库？

我很困惑，因为构建和运行错误误导了我。从他们那里，我无法弄清楚各种JavaServer Page Standard Tag Libraries之间的区别。例如，我看到：

I'm puzzled because of build and run errors that mislead me. From them, I can't quite figure out what the distinction is between the various JavaServer Page Standard Tag Libraries. For instance, I see:

jstl.jar (in Apache Tomcat)
jstl-1.2.jar (in Tomahawk examples)
jstl-impl.jar (in GlassFish)

过去，我'从 javax.servlet.jsp.jstl

jstl-api-1.2.jar
jstl-impl-1.2.jar

这些后者是我在执行JavaServer Faces（JSF）工作时唯一能够可靠使用的。

These latter are the only ones I seem to be able to use reliably in doing JavaServer Faces (JSF) work.

我发现没有wiki语句对比这些不同的JAR 。是的，我知道他们的年龄不同。我想知道，例如， jstl.jar 不应该是一个现代的，确定的，一个（ api 和 impl ）我只是使用错误的JSF库（例如 myfaces-api-1.2.8.jar ）来使用它？

There's no wiki statement I've found that contrasts these different JARs. Yeah, I know their ages are different. I wonder, for instance, if jstl.jar isn't supposed to be a modern, definitive, both in one (api and impl) and I'm just using the wrong JSF libraries (myfaces-api-1.2.8.jar, for instance) to go with it?

我的目的是建立一套明确的JAR用于使用MyFaces或RichFaces进行Facelet工作，这两个我最了解。

My purpose is to establish a definitive set of JARs for doing Facelet work using either MyFaces or RichFaces, the two I know best.

感谢任何能够解决问题的人最佳实践。

Thanks to anyone who can shed some light and best practice on this.
