The links on the page "Further Information about the Connector Architecture" are broken.
This is from the Java EE 5 Tutorial.
There are no scheduled updates to the Java EE 5 Tutorial. Lowering the priority, but keeping the issue open in case we do update the EE 5 Tutorial in the future.
We will not be updating the Java EE 5 Tutorial. Even if we wanted to update the links, I believe that the links for downloading the Connector Architecture 1.5 specification from the JCP web site are broken too. See http://jcp.org/aboutJava/communityprocess/final/jsr112/index.html.
The current version of the Connector Architecture is 1.6. The Java EE 6 Tutorial describes version 1.6 of the specification. The "Further Information about Resources" page at http://docs.oracle.com/javaee/6/tutorial/doc/bncjw.html in the Java EE 6 Tutorial provides the links for which you are looking.
