Hi everyone, I've been plugging away at adding support for inheritance to our JDO/JPA implementation for quite awhile, but now that I have something working that is compatible with the current SDK (1.2.6) I've made a preview release available for download: http://datanucleus-appengine.googlecode.com/files/appengine-orm-1.0.4.RC1.zip
This release provides support for inheritance of native datastore types and embedded classes. Base classes with relationships are completely untested and probably do not work. If you're excited to use inheritance in your object model please give it a spin and let me know how it goes. You can find information on using inheritance in JDO here: http://www.datanucleus.org/products/accessplatform_1_1/jdo/orm/inheritance.html Note that app engine _only_ supports the 4th option, "complete-table." You can find information on using inheritance in JPA here: http://www.datanucleus.org/products/accessplatform_1_1/jpa/orm/inheritance.html Note that app engine _only_ supports the 3rd option, "TABLE PER CLASS." You can find information on installing the JDO/JPA jars here: http://code.google.com/p/datanucleus-appengine/wiki/HowToUpdateTheSDKWithANewPluginVersion Note that this release does _not_ involve a change to the DataNucleus version so you can ignore those steps. Remember, this is a preview release, so the only guarantee I can provide is that the unit tests pass. Thanks!
