No sure, maybe you did find the solution already yourself. I think you
get a 405 because your servlet (?) only supports GET request. At least

Yes, there is a more detailed explanation of JDO under Java/Storing Data.
But it does not deal with the Guestbook example, which is a very nice little

There's no guarantee that both those threads are running on the same

Yeah, I can see your point. I've begun to like the datastore query class
better for queries, but for putting it into object form JDO query class

of the past 30sec restrictions, I heavily divided up the big

lot of tasks that I put into task queues. These refresh jobs are all
started with a few Cron jobs.
