Not quite the same, in this article pretty much all of the books are teaching Rails. The link you provided shows a different Java technology for each book. You only need one of the books to learn Rails.

I enjoyed the picture but:

Struts cookbook? Well thats not a requirement. There is the RoR cookbook. Add that to the pile.

IF you are making an xml-based external web service I don't care what language you still write the XSLT to give out as a public api. So thats another one to the ruby pile.

Struts in action? There are 2 learn struts books in that pile.

In any case if you think more than a few seconds about that image you will cut down the java side and incraese the ruby side to equalibrium.

That's a great point, I totally remember this. Everyone was like, 'We have scaffolding!'.

Now that I've switched from Django to Rails though, I have to say it is plesently surprising how nice of a framework it is... but from a Django to Rails perspective Rails is annoying to the point Merb has gained a lot of success. Anyways, I digress. Thanks for posting that image, had a good laugh about it.
