[appengine-java] Re: Upgrade issue with Google SDK 1.2.5
Had the same problem, just remapping the SDK fixed it. This is under WIndow-Preferences-Google-App Engine.

[appengine-java] Re: To specify Key or use auto generation
In 1, another problem is that I may not know the Keys of A and B at the
point of creation. For example, lets say I am doing something like this:
class Person {
}
class Group {
@Persistent(mappedBy = group)
ArrayListMembership memberships;
}
class Membership {
Key person;
Group group;
}
Now I would do:
Group g = new Group();
while(...) {
Membership m = new Membership();
g.memberships.add(m);
}
pm.makePersistent(g);
Now, when I create membership, I dont have the Group key (I do have the
person key), I can't really use it to create a new derived key for
membership. Or am I missing something?

Two ways:
1. Use concatenated Key of A and B for Key of C. Data model will ensure
there are no duplicates.
2. Use autogenerated Key and make sure you do not duplicate A B
relationship in code.
Which one would you choose? In 1, is a simple concatenation the best way to
go about it?

[appengine-java] Storing JDO extent in session - not serializable
My need is to implement database rowset paging behaviour.
i.e I want to create an Extent when session created and then on page
request browse the dataset from the last point.
The problem:
JDOExtent is not serializable and hence the code below throws an
extent.
Please suggest an alternative approach.
public class AgentInfoDao {
static final String q =SELECT FROM + AgentInformation.class.getName
() + order by appointmentDate asc;
ExtentAgentInformation extent = null;
IteratorAgentInformation resultIterator;
public void sessionCreated() {
PersistenceManager pm = PMF.get().getPersistenceManager();
extent = pm.getExtent(AgentInformation.class, false);
Query query = pm.newQuery(q);
query.setCandidates(extent);
CollectionAgentInformation result =
(Collection)query.execute();
resultIterator = result.iterator();
}
public ListAgentInformation fetchNextSet(int setCount){
log.info(Next Set of + setCount);
ListAgentInformation set = new ArrayListAgentInformation();
int c=0;
while(c setCount resultIterator.hasNext()){
// do something...
}

[appengine-java] JDO transaction does not start datastore's transaction.
Hi, here is introducing my JDO problem. Is it issue of datanucleus or me? Should I separate codes with txn when getting something from datastore with same PM? Thanks. --- ・What steps will reproduce the problem? 1.get PersistenceManager as pm. 2.invoke pm.getObjectById or iterate some query result outside txn. 3.txn.begin 4.invoke pm.getObjectById 5.change entity's properties. 6.txn.commit *Same issue occured if kind of entity is different between 2 and 4 or not. ・What is the expected output? What do you see instead? expected: It starts DatastoreService's transaction. instead: It does not start DatastoreService's transaction. (DatastoreXAResource#start is not invoked.) ・What version of the product are you using? On what operating system? SDK 1.2.5 on Windows XP/eclipse 3.4 ・Please provide any additional information below. If once invoke getObjectById or something outside txn, ManagedConnection instance is reused from ManagedConnectionPool at ConnectionManagerImpl by invoking allocateConnection. If that pooled connection was made at when it is not in txn, ConnectionManagerImpl#enlistResource is not invoked so it does not start Datastore's transaction. Also it does not register transaction listener so there is no way to remove this connection except Query#execute or closing PM. --- --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Re: Master/Detail relations and redundant data handling
I'm not sure if your taking of the problem is correct. To my mind it
runs:
You have Company and Employee. Company has many Employees and Employee
is working for one company. Normalized version looks like:
class Company {
@Persistent private String companyName;
@Persistent private String businessArea;
...
}
class Employee {
@Persistent private String name;
@Persistent private String address;
@ManyToOne
private Company company;
}
If you want to get all Employess working for a company you should
execute:
SELECT * FROM Employee e WHERE e.company.companyName = :nameParam
or if you want all Emloyees working for all IT companies you execute:
SELECT * FROM Employee e WHERE e.company.businessArea = 'IT'
...
But this query will not work in Google App Engine.
The solution is to resolve this query programmaticaly by running
several queries and filter it in memory or to denormalize this
scheme by moving some fields from Company to Employee
Something like:
class Epmloyee {
@Persistent String name;
@Persistent String address;
// copy of property fiels from Company
@Persistent private String companyName;
@Persistent private String businessArea;
@ManyToOne
private Company company;
}
and run
SELECT Object(Employee) FROM Employee e WHERE e.companyName
= :nameParam
The first solution allows keeping normalized version but the cost is
less effective query, the second requires to break strictly normalized
pattern but the query is much more effective (I think that it can be
10 or more times more effective). Also the second solution requires
more time while writing and updating.
But it is up to you what is more important, it is classical dilemma:
more reads or more writes.

[appengine-java] Re: Master/Detail relations and redundant data handling
Right, denormalization is promoted by the Max Ross video as in your
2nd case so from a software design perspective can the copy fields
in Employee be contained in their own class and referenced from
Employee in a fashion that allows JDO to still work such as:
class CompanyFK {
// copy of property fiels from Company
@Persistent private String companyName;
@Persistent private String businessArea;
@ManyToOne
private Company company;
}
class Employee {
@Persistent String name;
@Persistent String address;
CompanyFK compnayFK
}
This way all entities that include a FK to Company would use CompanyFK
and denormalized relations such as this would be managable (ie rather
than copy/paste of fields across many Entities). Does JDO allow this
level of control?

James, My situation is a bit different from yours. I did not upgrade. I installed the GWT SDK and Eclipse Plugin a week ago. Then ran into some problems and tried to uninstall the Google GWT features (all 3) to see if that would change the situation. When I tried to re-install them today, I noticed the missing plugin. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Persistence problem of an entity with two List of the same type
Hello.
Maybe, I'm missing something obvious in the documentation, but I can't
figure out why I cannot properly persist an entity which has two list-
fields of the same type properly.
I have the following persisted class:
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public final class A
implements Serializable
{
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
@PrimaryKey
private Key key;
@Persistent
private ListB list1 = new ArrayListB();
@Persistent
private ListB list2 = new ArrayListB();
}
where B is a very basic persisted class with only two persisted
attributes (and of course, a key).
Every time I persist an entity of A with 2 non-empty lists fields
list1 and list2, once I request this instance (in another
transaction), the list2 field is always empty.
Does it mean that there are currently some restrictions on App Engine,
which prevents to persist two collection attributes of the same type
at the same time? Do I need to annotate the two fields in a specific
way? I am running App Engine v1.2.5.
Thank you so much for your help. Regards,
Édouard

[appengine-java] JDO Sequences in AppEngine
Hey guys, I wanted to use a JDO persistence-backed Sequence to provide monotonically increasing visitor #'s in my webapp. A static variable doesn't cut it because I want the number to survive redeployments, upgrades, etc. I didn't see any info on Sequence in the wiki Using JDO section so I did this. It works but it seemed kinda hacky. Is this the best way to configure a JDO-backed Sequence in AppEngine? (FWIW I'm using the eclipse plug-in.) (1) Make the following file: MyProject/META-INF/package.jdo * This directory should already contain a jdoconfig.xml. * Both files will be autoplaced into MyProject/war/WEB-INF/classes/ META-INF on deploy. (2) Paste the following XML into package.jdo: ?xml version=1.0 encoding=UTF-8 ? jdo xmlns=http://java.sun.com/xml/ns/jdo/jdo; xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance; xsi:schemaLocation=http://java.sun.com/xml/ns/jdo/jdo http://java.sun.com/xml/ns/jdo/jdo_2_2.xsd; !-- name the package whatever you want -- package name=MyProject sequence name=VisitorSequence datastore- sequence=VISITOR_SEQUENCE strategy=contiguous / /package /jdo (3) When you need the next value in your application, call: PersistenceManager pm = //...allocate pm //the sequence name is package name.sequence name //from the corresponding tags in package.jdo Sequence seq = pm.getSequence(MyProject.VisitorSequence); //If strategy from package.jdo was contiguous, this has to happen //in a transaction. long nextValue = seq.nextValue(); --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] testing persistence with one to many relashionship
Hi all,
I am trying to test persistence, with:
class Foo implements Serializable {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key key;
}
When I call makePersistent on an instance, the key value is created
as expected. If I add a field:
@Persistent
private ListCategory children
Then the key is still null after the call to makePersistent. I can
see that in JDOStateManager, the creation of the pm is let to the
datastore, then a value of:
___entity_write_delayed___=Entity [Category(no-id-yet)]
but it ends without an id being set.
What did I miss ?

I dont know how to implement a back-end for an autosuggest query.
The idea is if a user type
sa, the servlet will query from the datastore, for example employee
names that starts with sa.
Any body knows how to implement this??
Thanks...

[appengine-java] Tasks not executed
Hi all,
I am just trying out the new Task Queue API for Java (many thanks)
and the insertion of tasks into a queue seems to work fine, but I
cannot see them being exectuted :-) Maybe I am not understanding a
trivial thing here...
This is the queue.xml:
?xml version=1.0 encoding=UTF-8?
queue-entries
queue
nameupdateTweets/name
rate5/s/rate
/queue
/queue-entries
It shows up correctly in the dashboard.
Next, I created a simple Grails action to insert a task into this
queue:
def triggerQueue = {
Queue queue = QueueFactory.getQueue('updateTweets')
TaskHandle handle = queue.add(url(/play/updateQueue).param
(screenName, 'hansamann'))
render Queued a new task for updateTweets queue...
}
This seems to work. I can call the triggerQueue action and it will
render the specified string, meaning no exceptions were thrown. I can
also see that the number of tasks in the queue in the dashboard has
been increased.
I can also call the task web hook /play/updateQueue directly, it
works. This is the implementation of that action:
def updateQueue = {
mailService.sendAdminMail(queue test - screenName $
{params.screenName}, ${params.screenName})
render 'OK'
}
Once I call this manually, I get an email just as supposed.
---
It is now about 30 mins since 2 tasks have been added to the queue, I
got no emails. The logs do not show exceptions that are task-specific.
The app-id is 'groovytweets'.
Has anyone else successfully tried it out and can post a quick
description?
Cheers
Sven

[appengine-java] Re: XMPP Error
I've been getting the same error, on what seems like the first request
since JVM-start/app-deployment.
It doesn't seem fatal, but does use some CPU time (1000-7000 cpu_ms,
where a typical request takes 100-200 cpu_ms), which is probably just
because the jvm/deployment is starting up.
