We have no success to implement gae junit test.
We use spring 2.5.6 and follow the
http://code.google.com/appengine/docs/java/howto/unittesting.html
.
public class BaseTestCase extends
AbstractDependencyInjectionSpringContextTests {
@Override
public void onSetUp() throws Exception {
ApiProxy.setEnvironmentForCurrentThread(new
TestEnvironment());
ApiProxy.setDelegate(new ApiProxyLocalImpl(new File("D:/work/
drp/src/drp/war")){});
super.onSetUp();
}
@Override
public void onTearDown() throws Exception {
super.onTearDown();
// not strictly necessary to null these out but there's no
harm either
ApiProxy.setDelegate(null);
ApiProxy.setEnvironmentForCurrentThread(null);
}
public String[] getConfigLocations() {
String[] configLocations = { "file:war/WEB-INF/

[appengine-java] how to build same entity group
I have two entity.
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class Person{
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
@Extension(vendorName="datanucleus", key="gae.encoded-pk",
value="true")
private String person_id;
}
public class Telephone{
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
@Extension(vendorName="datanucleus", key="gae.encoded-pk",
value="true")
private String telephone_id;
@Persistent
private String person_id; //this field point to Person
}
Person Module manager Person create/update/delete/query
Telephone module manaer telephone create/update/delete/query
Person can have 0 or mulity telephone but telephone only point to one
person or Telephone.person_id=null
Now there is a third module manager relation of Person and
Telephone .
if person have telephone( telephone1,telephone2,telephone3) and user
update person's telephone is telephone2,telephone3,telephone4,how
to implements this?
is there and code example? thants a lot

[appengine-java] Re: how to build same entity group
Hello Ikai L thanks for your reply. You just have to persist the Person first, or create a Person, attach Telephone entities, then call pm.makePersistent() on the Person. >>but this is problem. Telephone must not belong to Person. Telephone module manaer telephone create/update/delete/query , telphone have many active or property to be managered and then there is no idea of Person I need set Telephone.person only after this person have buy the telephone. there is any other idea ? thanks a lot -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

[appengine-java] Re: how to build same entity group
for instance, you can just use a Key and reference
the Person in the Telephone.
>you are right. and i just do it as you say.
public class Telephone{
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
@Extension(vendorName="datanucleus", key="gae.encoded-pk",
value="true")
private String telephone_id;
@Persistent
private String person_id; //this field point to Person
}
my question is "
if person have telephone( telephone1,telephone2,telephone3) and user
update person's telephone is telephone2,telephone3,telephone4,how
to implements this?
"
but in a same transactions , I need update 2 telephone
object .--telephone1.person_id=null
telephone4.person_id=person_id.
and the 2 telephone object is not in same entity group.
the question seem to equal " how to update multi object (same
class) in same transaction?"
Thank you for your help
