El-API is the API. Jasper, I think is the impl. The EL packages in facelets are needed for pre-jsp 2.1 containers so facelets can be used in any environment that JSF 1.1 can be used in. The facelets website tells you how to configure facelets to use the unified el. I don't know what commons-el is.

Hi,

I am lately very confused with the el-api and its implementations when using
Tomcat 6.0, MyFaces 1.2, Facelets 1.1.

It's said JavaEE 5 has an unified EL, so I reckon Tomcat 6.0 has the EL implemented. And I indeed found el-api.jar in its shared "lib" directory.
And I also found a "jasper-el.jar". Is this an implementation for the
el-api.jar?

There is also a commons-el under apache foundation. Its website says it's an implementation of the EL for JSP2.0. So what's the difference between this
impl and the jasper-el.jar within Tomcat 6.0 distribution?

I also noticed Facelets 1.1 requires EL implementation. I downloaded its zip file and found a el-api.jar, and the .class files of this jar are different from the one within Tomcat 6.0. So the question is who is maintaining the
el-api, and what are its versions?

Please could someone help me out. Thanks in advance!

Fan
