[appengine-java] Re: JDO - Add a child - Error

Hi! I have a problem when add a class "Equipo"(child) one
"Torneo"(parent).

The code:
Transaction tx = pm.currentTransaction();

                try {
                        tx.begin();

                        unTorneo.agregarEquipo(unEquipo);
                        //pm.makePersistent(unEquipo);
            Torneo tor = (Torneo) pm.detachCopy(unTorneo);
                        pm.makePersistent(tor);

                        tx.commit();

                       
System.out.println("persistioTorneoConEquipo");
                } finally {
                         //pm.close();
                        if (tx.isActive()) {

[appengine-java] Re: Persist child - Problem

[lisandrodc]

Thanks andrew! My class Equipo has @persistence capable and
and serializable... The code:
import java.io.Serializable;
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.appengine.api.datastore.Key;

@PersistenceCapable(identityType =
IdentityType.APPLICATION,detachable="true")
public class Equipo implements Serializable {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key id;
@Persistent
private String nombre;
@Persistent
private String imagen;



I'm not understand because it not pesist in the datastore.
Regards!
Lisandro

The dev server is not the only way to run app engine locally.
Take a look at these projects to see if they can meet your needs...

You sure can, but you should be aware of many of the limitations of the
development server:

- it's slow
- the datastore can be wiped on upgrade (this is an ugly bug that pops it
head up now and then)
- it's single threaded
- no real accounts support
- ... many, many more limitations

[appengine-java] Concurrency issue when dealing with datastore

[cghersi]

Hi all,
I'm very new with GoogleAppEngine, and I cannot yet understand how to
deal with Transactions and concurrency.
I've got a servlet called by a queue task where I need to manipulate
several kind of objects.
I'm not able to use the Transactions, as I'm updating several objects
not belonging to the same entity group.
I'm facing a "org.datanucleus.exceptions.NucleusDataStoreException:
Concurrent Modification" problem when trying to close my
PersistenceManager object at the end of the doPost() method of the
servlet.

Is there a known pattern to face with this problem?

Thank you very much.
Bye
cghersi

Re: [appengine-java] Re: DataStore embeds equals signs ("=") into saved file

Hi,

I explored the below thread, but I'm still not sure how to fix the problem.   
Is it that the file is encoded as one format originally and then GAE tries to 
encode it differently?

thanks

[appengine-java] May I use AppEngine SDK internally without deploy to Google AppEngine?

some custom hooks instead of re-writing the app).

May I do that?

[appengine-java] Upload to blobstore without form

[Cyrille Vincey]

Has any of you succeeded in coding a servlet that uploads a file to the
blobstore WITHOUT passing through a post jsp form ?
(apologies, this might have been discussed a zillion time already in this
group)

Would be VERY helpful to me.
Thanks in advance,
cyrille
