I refer to the section "Java | Storing Data | Creating, Getting and Deleting Data | Keys" in the GAE documentation. What it says is that for any key type that your persistent entity class uses, keys (or key elements) of type String can be set by the app, but that for type Long the datastore sets this and the app cannot:
"The app can provide the ID portion of the key as a string when the object is created, or it can allow the datastore to generate a numeric ID automatically." This should explain your exceptions: "javax.jdo.JDOFatalUserException: Attempt was made to manually set the id component of a Key primary key. If you want to control the value of the primary key, set the name component instead." You are now using a String, which is allowed for your key. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
