Hello,
I have been wanting to know how to do this for a while now, but don't know
where to find information on how to do this. I simply want to know how to
setup my project so I can have a JDO object in the "server" package (so I
can use classes like com.google.appengine.api.datastore.Key and
javax.jdo.listener.StoreCallback), and request a list of those objects from
my client side code. Currently I store my JDO object in my "client" package.
So when a user clicks a button to retrieve all the People objects I can get
back a List<People>. I'm sure these are some fundamentally basic steps I
just don't know to acheive. Do you need a persistent object on the server
side and a transfer object on the client? If so how do you send the data to
the transfer object. Thanks
currently have: (and want it instead in com.myapp.server but also to
retrieve say List<People> )
in com.myapp.client
import javax.jdo.annotations.IdGeneratorStrategy;
import javax.jdo.annotations.IdentityType;
import javax.jdo.annotations.PersistenceCapable;
import javax.jdo.annotations.Persistent;
import javax.jdo.annotations.PrimaryKey;
import com.google.gwt.user.client.rpc.IsSerializable;
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class People implements IsSerializable {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Long pKeyRiderID;
@Persistent
private String lastName;
...
currently in com.myapp.server:
private List<People> get() {
PersistenceManager pm = PMF.get().getPersistenceManager();
List<People> result = null;
try {
String q = "select from " + People.class.getName();
result = new ArrayList<People>((List<People>)
pm.newQuery(q).execute());
} finally {
pm.close();
}
return result;
}
