I think one of the best ways to start learning about the datastore is to use the low-level API:
http://code.google.com/appengine/docs/java/javadoc/com/google/appengine/api/datastore/package-summary.html We changed our docs recently to show examples using this. As far as open source projects go, you can take a look at how Objectify and Twig (there are more, please list!) are implemented using the low-level API. -- Ikai Lan Developer Programs Engineer, Google App Engine Blogger: http://googleappengine.blogspot.com Reddit: http://www.reddit.com/r/appengine Twitter: http://twitter.com/app_engine On Tue, Feb 22, 2011 at 7:49 AM, Ronmell Fuentes <ringe...@gmail.com> wrote: > Hi John, > acording to my expertise in DataStore, you'll get more know-how when > running the example > you'll see the creation of the files and all the data that datastore deals > with. > try running the helloWorld example and try to > 1. create one own Object to be stored (kinda POJO); > 2. create a PersistenceManager and instance it, to save the POJO. > 3. save the POJO and retrieve it to show the contents. > > Of course, when one is trying to run the examples the bugs and problems > appear, but > that's part of our job.
