Java EE API规范的官方资源是什么？

Question

I know a few official sources like the java Java EE 6 tutorial.

But I was wondering, which one are the official sources for properly learning the spec of every API and any other resource related to the Java EE environment? Which resources ppl use to keep track of future versions without being actively participating of any container or spec development?

I hope this question is specific enough by suggesting only official links.

EDIT: About https://java.net/projects/javaee-spec/pages/Home . It has a lot of links for several document versions and optional content. I wanted just one single resource for each API, a complete version. Let's take for example the annotated ECMAScript 5 spec ( http://es5.github.io/ ). Assuming the links are permanent it would be very nice to point out the complete documents for the APIs from Java EE 6.

Answer 1

Java EE 6 APIs are available at:

http://docs.oracle.com/javaee/6/api/

These can be downloaded from:

http://www.oracle.com/technetwork/java/javasebusiness/downloads/java-archive-downloads-eedocs-419425.html#java_ee_6u1_docs-JPR

Answer 2

https://java.net/projects/javaee-spec/pages/Home

But not really sure why you couldn't google that.
