Hello, I have found the following tutorial on the JDO which is used in AppEngine
http://code.google.com/appengine/docs/java/datastore/jdo/ but would like a somewhat more in-depth step-by-step resource on JDO. I was wondering, given it was published in 2003 when JDO 2.0 was not yet out and given that AppEngine's JDO is 2.3, how relevant is the foolowing book to learning JDO? http://www.amazon.com/Java-Data-Objects-David-Jordan/dp/0596002769/ref=sr_1_12?ie=UTF8&qid=1325862357&sr=8-12 Is it still worth reading or is it completely out of date? I cannot find a more up-to-date comprehensive reference on JDO. Thanks, John Goche -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
