I'm trying to delete all entities in my datastore but I receive the
following error:
javax.jdo.JDOUserException: One or more instances could not be deleted...
NestedThrowablesStackTrace:
java.lang.IllegalArgumentException: id cannot be zero...
Caused by:java.lang.IllegalArgumentException: id cannot be zero....
For the following code:
public void deleteAllMyType() {
PersistenceManager pm = PMF.get().getPersistenceManager();
Query query = pm.newQuery(MyType.class);
try {
query.deletePersistentAll();
//List<MyType> clist = (List<MyType>) query.execute();
//pm.deletePersistentAll(clist); // This doesn't work either
} finally {
query.closeAll();
pm.close();
}
}
My entity class looks like this:
@PersistenceCapable(identityType = IdentityType.APPLICATION)//, detachable =
"false")
public class MyType implements Serializable {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Long id;
@Persistent
private String name;
.
.
.
}
