GAE datastore (save object)

I am new at GAE Api.

At the moment I use : com.google.appengine.api.datastore.DatastoreService in order to save something in database.

At the moment I need to save list of items in database. should I use JDO ? Or can I do this without it? :-)

I need to save Array in datastore. but I can't do something like that:

entity = new Entity(key);
entity.setProperty("uid", arrayObject);

Generally, I suggest you to use Objectify for Datastore Operations. You save a lot of time wrapping datastore entities in java objects:

For your question, Array type is not supported by GAE Datastore. Here a list of supported type. If you need to save an array of items, you have to use a List object
