[appengine-java] Learning JDO for AppEngine

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

Re: [appengine-java] DataStoreFactory

No, these should be part of the App Engine SDK. Are you using the Eclipse plugin? When you create a new "Web Application Project" these are already included. -- Ikai Lan Developer Programs Engineer, Google App Engine plus.ikailan.com | twitter.com/ikai On Thu, Jan 5, 2012 at 2:13 AM, SAS wrote

[appengine-java] Re: How to Limit/Slow Down Task Queue Execution

The problem with a cron every 30 seconds is that it will fire, and start up instances if you have none running - or extra instances if you have one busy - even where there is no "work" to be done. Maybe you have this non-time-critical work to be done once a day (as is my case also) and you don't

Re: [appengine-java] Error

Try turning the widget 3 degrees to the left. We're going to need more information than that. "Internal server error" is most often caused by an exception being thrown in your code and not caught - you should see details in the error log (on production) or on the console (on the dev server). On
