Where is commons-lang.jar???

[olgajurel]

Hello:
I have donwloaded Seam 1.0 beta 2, and Unzip/install it into a directory, then I have configured a new project in my Eclipse Ide (Rational Application Developer V6.0):
· I have added all the libraries (lib, embedded-ejb/lib, microcontainer/lib)
· I have added all source in theirs folders

But I have a compilation problem: Interceptor.java dont find java.lang.annotation.Annotation.
Where is commons-lang.jar???????????
What did I do wrong?????
I have tried to conect to CVSRepository but I have a timeout exception socket.

Thanks for all

java.lang.annotation.Annotation is absolutely nothing to do with commons-lang.

It is an interface built-in to Java SE 5.
