This group concerns the book Java Data Objects, by Robin Roos. It is maintained by the author.
Once you have joined this group you may download the complete book in PDF form from the files area. You can't print this copy, but it should serve as a valuable reference to transparent persistence with the Java Data Objects API.
It takes months for a revised book edition to appear in hard copy, but electronic updates are quick. I will use this forum to advertise the availability of new electronic editions of the book, and other events of interest to the JDO community.
Only the author may post to the group, so traffic will be low.
