Well, the whole reason Craig Russell and I are on this site is in support of a promotion of ourJDO book published by O'Reilly. There are 3 books out now on JDO, but if you look at the average customer review and sales rank at Amazon, you will see that we have the most popular book so far. Craig and I collectively have close to 30 years of experience with object persistence technology and he is the JDO spec lead, so we were well qualified for writing the book.
You can also go to JDOcentral which has lots of white papers, web links, discussion forums, etc. focused on JDO.
I believe at the end of today, four of our books will be given out to people that participated in these JDO discussions, so maybe you will be lucky!

Some would say I am biased. But most consider JDO orders of magnitude easier to learn than EJB. This is because it lets you directly persist your Java classes, only requiring that you have a null constructor. There are about 10 methods you will need to learn for about 90% of your software development. JDO uses your application's normal navigation of your object models as the basis for retrieving objects from the database, so most of the calls to get data is not even visible at the application level. Our chapter 1, posted on the web, walks through all the CRUD operations one performs when operating on objects with JDO. Read that chapter and decide for yourself whether it is easier than EJB or not.
