one more doubt similar/related to previous one :
i want to fetch object(s) from datastore, cache it to Memcache and fetch it
from Memcache for further requests. and if any change happens to data i want
to update the object(s) to datastore straight away using cashed instance of
object instead of fetching it (again) form datastore and then updating it.

Data data = cache.get(key);
data.setValue(new updated value);
pm.makePersistent(data);
cache.put(key, data);

will issue a keys-only query that fetches only the key, not the entire

Hello hello and welcome to the very first installment of JDO/JPA

Creating A Bidrectional Owned One-To-Many
Suppose you're building a book catalog application and you want to
model
books and chapters. Books contain chapters. A chapter cannot exist
without
a book, so if you delete a book you want its chapters automatically
deleted
along with it. You also want to each chapter to have a reference to
the
book that owns it. Sounds like a bidrectional, owned, one-to-many
relationship is just the thing. First we'll set up our model objects
and
then we'll add some code to create a Book with 2 Chapters.
JPA:
@Entity
public class Book {
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
private Key id;
private String title;
@OneToMany(mappedBy = book, cascade = CascadeType.ALL)
private ListChapter chapters = new ArrayListChapter();
// getters and setters
}
@Entity
public class Chapter {
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
private Key id;
private String title;
private int numPages;
@ManyToOne(fetch = FetchType.LAZY)
private Book book;
// getters and setters
}
Now let's create a book with two chapters (we'll assume someone else
is
creating and closing an EntityManager named 'em' for us):
Book b = new Book();
b.setTitle(JPA 4eva);
Chapter c1 = new Chapter();
c1.setTitle(Intro);
c1.setNumPages(10);
b.getChapters().add(c1);
Chapter c2 = new Chapter();
c2.setTitle(Configuration);
c2.setNumPages(9);
b.getChapters().add(c2);
em.getTransaction().begin();
try {
em.persist(b);
em.getTransaction().commit();
} finally {
if (em.getTransaction().isActive()) {
em.getTransaction().rollback();
}
}
JDO:
@PersistenceCapable(identityType = IdentityType.APPLICATION,
detachable =
true)
public class Book {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key id;
private String title;
@Persistent(mappedBy = book)
@Element(dependent = true)
private ListChapter chapters = new ArrayListChapter();
// getters and setters
}
@PersistenceCapable(identityType = IdentityType.APPLICATION,
detachable =
true)
public class Chapter {

Is there a way to create static files from a servlet? We are using an image upload JSP, but we currently store the image in the data store, and we serve the image back with a servlet.

[appengine-java] Re: JSP errors in hosted mode
Hi Andy, At this point, no. For JSP errors generated by javac, the error will refer to locations inside the generated servlet class, instead of inside the JSP file it came from. Errors from the JSP compiler, on the other hand, *will*generally refer to the actual JSP file/line that caused the error. I see that you've already created an issue in the public tracker, which is exactly the right approach. Incidentally, you created an issue *just minutes* before I created essentially the same issue (issue 2131http://code.google.com/p/googleappengine/issues/detail?id=2131) on your behalf!

if i fill queue without TaskOption.url: queue = QueueFactory.getDefaultQueue() queue.add() or queue = QueueFactory.getQueue(myqueue) queue.add() i get URLs in local and prod: /_ah/queue instead of /_ah/queue/default or /_ah/queue/myqueue Is it a bug or am i doing something wrong? If i use Python SDK, default urls are correct... --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Hi Brian. What field types are in your command class? If you're using
anything besides a String, Long, or Boolean (taken from the snippet I posted

Thanks.
The problem I encountered is caused by the Spring form tag, I have
fixed it.
If you want to use form tag, you must override the initBinder method
of WebBindingInitializer, otherwise you will get a error:
org.springframework.web.servlet.tags.RequestContextAwareTag
doStartTag: access denied (java.lang.RuntimePermission getClassLoader)
java.security.AccessControlException: access denied
(java.lang.RuntimePermission getClassLoader)
..
Nested in org.springframework.web.util.NestedServletException: Request
processing failed; nested exception is java.lang.ClassCastException:
java.security.AccessControlException cannot be cast to
javax.servlet.ServletException:
java.lang.ClassCastException: java.security.AccessControlException
cannot be cast to javax.servlet.ServletException
You should write your own WebBindingInitializer class
{code}
public class TheFocusBindingInitializer implements
WebBindingInitializer {
@Override
public void initBinder(WebDataBinder binder, WebRequest request)
{
binder.registerCustomEditor(String.class,
new StringTrimmerEditor(false));
}
}
{code}
and then inject it into the AnnotationMethodHandlerAdapter by the
following configuration:
{xml}
bean
class=org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter
property name=webBindingInitializer
bean
class=com.appspot.thefocus.web.TheFocusBindingInitializer /

[appengine-java] Re: Java Security Error
Hi Ravi. As Gianni wrote, you can't use JDBC directly. Using App Engine's datastore would be ideal, but if you must use an existing RDBMS, you'll have to put a web service in front of it. This can be as simple as a servlet or script (not running on App Engine) which retrieves the data and returns it as plain text, XML, JSON, or another format of your choice. You can call this servlet or script using App Engine's URL Fetch service. - Jason On Mon, Sep 14, 2009 at 10:11 AM, Ravi Mandliya funkyr...@gmail.com wrote: Thanks for the reply...

Hi Everyone,
I've noticed that CPU occasionally spikes when creating an
HTTPSession. It only seems to happen when it's been awhile since an
app has been accessed or when an app is initially deployed.
For example, I created a simple test servlet that creates a session
and and writes a response:
protected void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
req.getSession();
PrintWriter writer = resp.getWriter();
writer.write(Test Complete);
writer.flush();
writer.close();
}
When I deploy the app and invoke the servlet for the first time, I see
the following in the admin console:
09-15 05:57AM 29.487 /test 200 7184ms 4381cpu_ms 65api_cpu_ms 0kb
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.6) Gecko/
2009011913 Firefox/3.0.6 (.NET C
Note the high CPU and long response time.
Subsequent session creations are much faster. If I delete my cookies
and re-invoke the servlet, CPU is approx. 70-80ms.
Now, if I leave the app for awhile (let's say an hour) and hit the
servlet again, CPU is once again through the roof for the initial
GET.
Any thoughts about what's going on here? I know that Google's session
management involves memcache and the datastore. Could the high CPU be
a side-effect of some initialization routine, etc...?

[appengine-java] Re: CPU Occasionally Spikes when HttpSession is Created
App Engine retires and spins up new instances of your app based on demand.
If a new instance of your app is being created, you'll see higher CPU then
normal as all of your code gets reloaded and initialized. This sounds like
the behavior you're seeing. One way to test that is to write a logging
statement in your Servlet's init() method.

[appengine-java] Re: JSP errors in hosted mode
Hi Andy, Actually, both the JSP compiler (Jasper) and javac process your JSPs. Jasper's compiler is really more of a pre-processor than an actual compiler: it just converts a JSP into source code for a Java servlet, which javac then compiles into Java bytecode. The problem comes when the Java servlet source that's generated by Jasper is malformed (due to errors in the JSP) and causes javac to generate errors. Those errors, as you noticed, refer to the locations within the generated servlet source code instead of in the original JSP. Internally, Jasper does maintain source mappings between the two, though, so it should be possible for the App Engine SDK to *always* report errors in terms of the original JSP. Keith On Wed, Sep 16, 2009 at 4:12 PM, andy asaut...@gmail.com wrote: Thanks Keith. I somewhat understand your point. Since you say the JSP compiler would give the desired information is there a way to configure the hosted mode to use the JSP compiler instead of javac? From the IRC chat today it was suggested that I add an issue. The issue I added was http://code.google.com/p/googleappengine/issues/detail?id=2132. If anyone else feels this is an issue please feel free to star the issue. Thanks again. On Sep 16, 11:49 am, Keith Platfoot kplatf...@google.com wrote: Hi Andy, At this point, no. For JSP errors generated by javac, the error will refer to locations inside the generated servlet class, instead of inside the JSP file it came from. Errors from the JSP compiler, on the other hand, *will*generally refer to the actual JSP file/line that caused the error. I see that you've already created an issue in the public tracker, which is exactly the right approach. Incidentally, you created an issue *just minutes* before I created essentially the same issue (issue 2131http://code.google.com/p/googleappengine/issues/detail?id=2131) on your behalf! That's ok, though; I'll go ahead and mark mine as a duplicate.

Hi Everyone,
I've noticed that CPU occasionally spikes when creating an
HTTPSession. It only seems to happen when it's been awhile since an
app has been accessed or when an app is initially deployed.
For example, I created a simple test servlet that creates a session
and and writes a response:
protected void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
req.getSession();
PrintWriter writer = resp.getWriter();
writer.write(Test Complete);
writer.flush();
writer.close();
}
When I deploy the app and invoke the servlet for the first time, I see
the following in the admin console:
09-15 05:57AM 29.487 /test 200 7184ms 4381cpu_ms 65api_cpu_ms 0kb
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.6) Gecko/
2009011913 Firefox/3.0.6 (.NET C
Note the high CPU and long response time.
Subsequent session creations are much faster. If I delete my cookies
and re-invoke the servlet, CPU is approx. 70-80ms.
Now, if I leave the app for awhile (let's say an hour) and hit the
servlet again, CPU is once again through the roof for the initial
GET.
Any thoughts about what's going on here? I know that Google's session
management involves memcache and the datastore. Could the high CPU be
a side-effect of some initialization routine, etc...?
Thanks for the feedback,
Jamie

[appengine-java] Re: Detching an object graph with JDO
You can declare a field to be in the default fetch group if you always want
the field to be available:
@Persistent(defaultFetchGroup = true)
private ListValue values;
If you don't want to go with this approach, you can also touch the field
that you want (e.g. call item.getItemValues()) before calling pm.close.
After detaching the object, the values field will be available since they
will have been lazily fetched with the getter call.

If i have a declaration like this:

detachable = true)
@FetchGroup(name = ItemValues, members = { @Persistent(name =
values) })
public class Item implements Serializable {
//...

And i want to get an entity from the datastore including the field
values. I have to the FetchGroup ItemValues to the FetchPlan:
pm.setDetachAllOnCommit(true);
pm.getFetchPlan().addGroup(ItemValues);
Query query = pm.newQuery(Item.class);

This way all the basic fields and the field values will be filled when
the query returns.

[appengine-java] Re: Bulk update throws exception
Hi Anita. I don't understand your data model -- if you are modeling the
relationship between entities of type A and entities of type B using
entities of type C, why do entities of type A have direct references to
entities of type B and vice versa?
Either way, the reason you're getting this error is because you're
inadvertently attempting to set an owned relationship between entities of
types A and B under type C, and doing this tries to modify the keys of types
A and B after they've been persisted, which you can't do. Try changing the
following:
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class TableC implements Serializable{
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key id;
@Persistent
private Key tablea;
@Persistent
private Key tableb;
.
This should just store a reference to the entity's key (unowned
relationship) rather than trying to modify the keys of the A and B entities.

Hi Jason,
I could solve my previous problem. But now i am facing some other
problem with many to many relationship tables.
My schema looks as follows:
TableA --- TableC - TableB
which means there is many to many relationship between TableA
TableB. So i want TableA and TableB primary keys into TableC as
foreign key.
TableA class looks as follows:
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class TableA implements Serializable{
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key id;
..
@Persistent(defaultFetchGroup=true)
private SetKey tableB = new HashSetKey();
..
(some getter setter)
TableB class looks as follows:
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class TableB implements Serializable{
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key id;
..
@Persistent(defaultFetchGroup=true)
private SetKey tableA = new HashSetKey();
..
(some getter setter)
TableC class looks as follows:
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class TableC implements Serializable{
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key id;
@Persistent
private TableA tablea;
@Persistent
private TableB tableb;
.
(some getter setter)
While adding data into TableC i use following code:
Query query1 = pm.newQuery(TableA.class);
ListTableA results1 = (ListTableA) query1.execute();
TableA tableA= results1.get(0);
Query query2 = pm.newQuery(TableB.class);
ListTableB results2 = (ListTableB) query2.execute();
TableB tableB= results2.get(0);
tableA.add(tableB);
tableB.add(tableA);
At this point TableA and TableB values are getting update but while
entering data into TableC the problem comes.
TableC tableC = new TableC();
tableC.setTableA(tableA);
tableC.setTableB(tableB);
pm.makePersistent(tableC); -- at this point it gives me A parent
cannot be established or changed once an object has been persisted.
Can you please tell me were i am going wrong?
Thanks

[appengine-java] Is the Google Collections framework already in deployed environment?
I'd like to start using the Google Collections framework (ImmutableList, etc) in my AppEngine project. I see that it is already available in the SDK but I am wondering if it is safe to assume that it is present in the production deployed environment. In other words, is it necessary to explicitly include the JAR in my WEB-INF/lib directory? - Jim --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[google-appengine] Re: 'ReferenceProperty' query filtering?
Using the query interface or building a query in code (with filter) are the
same. Neither is capable of the kind of join you want to do.
Two simple ways to accomplish what you are trying to do are:
Method 1:
Using your current model, structure the question as:
theowner = PetOwner.all().filter('name =', 'johndoe').get()
print theowner.name
for pet in theowner.pet_set:
print pet.name, pet.type
This will use a bunch of API calls though, as I recall.
Method 2:
Add a ownerName (db.StringProperty()) to your Pet model, when you set the
owner also set the ownerName. Then your query could look like:
johnspets = Pet.all().filter('ownerName =', 'johndoe').fetch(limit=1000)
for pet in johnspets:
print pet.ownerName, pet.name, pet.type
This is the method I have been using, a lot. It make reporting much easier
in the reporting intensive apps I develop.

Thanks for the response, works nice, however coming from PHP/MySQL
this seems strange to me.
We have two 'tables' and are trying to perform a query to link them,
however this solution causes two queries on the 'database' to be
performed, which are logged against you for your quotas.
I'm used to joins:
http://dev.mysql.com/doc/refman/5.0/en/join.html
One query linking two or more tables for the data you need.
Is Google App Engine's 'query' function not able to do anything like
this? Is GQL better than GAE's 'Query'?

I am sorry I replied to the thread when I was not at my dev machine,

query.filter('owner = ', owner)
This should work.

I visited the doc you referenced, but the page does not mention
anything about the style of query filters or any information on
construction of queries with ReferenceProperty that I could find.
Does the query filter you wrote work on your side?
I broke our your query:
PetOwner.all().filter('name =', 'johndoe')
Which worked fine, however it was in placing it inside the
query.filter that I get an error.
Do you not get an error structured like this?

Jumping into GAE, I found the ReferenceProperty interesting but

My question can expand on the example from:

class PetOwner(db.Model):
name = db.StringProperty()
class Pet(db.Model):
name = db.StringProperty()
type = db.StringProperty() # cat, dog, etc.
owner = db.ReferenceProperty(PetOwner)
Let's do a query to select all cats with a specific owner.
query = db.Query(Pet)
query = Pet.all()
query.filter('type = ', 'Cat')
results = query.fetch(limit=10)
for result in results:
output = result.name
return output
What can I add to this to filter only those where 'owner' is
'johndoe'?
I tried:
query.filter('owner = ', 'johndoe')
However it fails to return me a result, and I know you can pull the
owner name via 'pet.owner.name' however trying:
query.filter('owner.name = ', 'johndoe')
Also fails, though it made sense for what should work. Does anyone
know the proper method?

[google-appengine] doubt with detachable property...
hi,
I tried the Updating an Object (using detachable property) example given
herehttp://code.google.com/appengine/docs/java/datastore/creatinggettinganddeletingdata.html#Updating_an_Object.
Later I found that even if I do not add *detachable=true *property to my
JDO class it works without any problem. Is it ok to work without detachable
property or it just worked with my case. Following is the code I tried :
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class Data{
@SuppressWarnings(unused)
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Long id;
@Persistent
private String value;
public Data(String value){
this.value = value;

public void setValue(String value){
this.value = value;

[google-appengine] Re: doubt with detachable property...
one more doubt similar/related to previous one :
i want to fetch object(s) from datastore, cache it to Memcache and fetch it
from Memcache for further requests. and if any change happens to data i want
to update the object(s) to datastore straight away using cashed instance of
object instead of fetching it (again) form datastore and then updating it.
following is a code snippet:
Data data = cache.get(key);
data.setValue(new updated value);
pm.makePersistent(data);
cache.put(key, data);
thanks.

[google-appengine] using a variable to buffer cache data...
hi, my app needs to store some data to datastore for each every request, say 1 object per request which causes high cpu usage per request. to minimize the cpu usage per request, instead of adding the object directly to datastore i add the object to a LinkedList (every request) and use a cron which moves objects form the LinkedList to datastrore periodically, say every min. I feel it is not a good practice. I don't want to use memcache (instead of server ram) to store my LinkedList because delay in fetching and storing the list form/to memcache may cause loss of data from upcomming requests (or previous request). I don't want to use task queue either for some reasons. Experts please comment on this kind of implementation. Losses Benefits, any alternative good practice.

[google-appengine] Re: using a variable to buffer cache data...
Quite simply wont work. It might appear to work for a while, but it will soon break. AppEngine is distributed, and runs on many machines. You can cache global variables between requests. But its just a bonus cache, cant store data there. Each request might hit a different instance, instances will be flushed without warning, and there is strong evidence that cron jobs hit different instances to ones serving web visitors anyway. Memcache will give more persistance, (ie less likly the data disappear on you) - but even that can be flushed or become unavailable. Again its just a cache - not for data. If you want to store the data have to use the datastore. Fundermentally, writing in 'batches' like you propose is not going to save much, because the same datastore API calls are still going to have to be made, just there can be some optimization as the task is similar. It might save some tho because the index writes can be batched.

Not sure if 'template.Template()' takes a str and makes it into a
'template' able to be rendered, does this code work on your side?
I even tried scrapping the way I pull the template and using your
method:
foo = db.get(templatekey).templatetext
Before that, I had to do another DB query to pull the key value of the

correction: you'll need to wrap template_values in template.Context();
template.render() does this for you automagically.

[google-appengine] Re: using a variable to buffer cache data...
Hi Prashant, In addition to what Barry says below, a couple of comments: - You can safely ignore the 'high cpu' warnings if you've already done what you can to optimize the page. You're not going to hit any invisible limits based on them, just the usual CPU quota etc. - If 'eventual' writes are good enough, you may want to look into using the task queue. You can enqueue the write in the task queue, which will do it offline and avoid making the user wait. -Nick Johnson On Wed, Sep 16, 2009 at 2:11 PM, Prashant antsh...@gmail.com wrote: hi, my app needs to store some data to datastore for each every request, say 1 object per request which causes high cpu usage per request. to minimize the cpu usage per request, instead of adding the object directly to datastore i add the object to a LinkedList (every request) and use a cron which moves objects form the LinkedList to datastrore periodically, say every min.

I don't fully understand exactly what the problem is you are trying to optimize, however, in general if the user is in a browser, there is a HUGE pool of completely free CPU resources available by moving program logic into javascript on the page. For example, as the user is typing, you could be doing the splitting in real-time, and using XMLHttpRequests to query the data store little by little. -Joshua On Sep 16, 2009, at 1:03 AM, Larkin2 wrote: My application is comprised of semicolon delimited phrases or sentence fragments.

[google-appengine] discounts for non-profit organizations
Hi, I just wanted to bring up the idea of discounts for non-profit organizations, or for apps that you deem doing good work for the world. While the free limit is generous, some applications can easily go over these limits, and at this point AppEngine becomes less of a good deal for organizations who might be able to get discounts from other hosting providers. I also am under the impression that some of these discounts are tax deductible, so while it might mean a little extra billing infrastructure to deal with it, it might not be like you're just losing all that money entirely, and you'll be helping out some good groups.

[google-appengine] Future of Google App Engine?
I hope this posting doesn't come across as harsh. I'm just being pragmatic about what I need to do for the applications I'm currently running and developing on Google App Engine and for the users on those applications. I read the email Maintenance Schedule for 2009 with some dismay, the three new maintenance slots plus the previous maintenance and service issues in July mean the application uptime for July-Dec is, at best, 3 nines. 5pm PST sits directly in the middle of my applications heaviest usage time (7-9pm EST) making the apparent uptime for July- Dec of this year well under 2 nines. I've been following with interest the problems that Peter has been having, his open letter and Ryan's response. So the real question to the GAE team is: When will GAE stop being a preview release and become an actual service offering; with SLA's, 24/7 support, customer friendly maintenance windows and 4 or 5 nines of uptime? Is this on a roadmap that can be made public? The _Why App Engine_ page says Google has a reputation for highly reliable, high performance infrastructure. With App Engine you can take advantage of the 10 years of knowledge Google has in running massively scalable, performance driven systems. and that is what initially attracted me to the service. What made me actually develop on it was how easy it was to publish and maintain applications and versions. Unfortunately the ongoing downtime, performance and reliability issues may be driving me away.

Since many people will be requesting this page at the same time. Anyone can explain me how to lower it down. Again, its a very simple website, no animation. Just few images for button nd all. I am on free quota. So please let me know that by example or by calculation that if my cpu usage for one request is 2410 ms and If I expect more than 1000 request per hour then what will happen to my site.

[google-appengine] Re: Case sensitivity
Hi Johnc, I just updated my answer to your question on Stack Overflow. The short story is that you can do this by writing a handler that redirects users from any page that includes an uppercase character to the same URL without it. This could be extended to a handler that goes first in the list and rewrites all requests, not just ones for static content. I'd suggest watching the logs and fixing links as you can, though - the redirect will add a little bit of latency to requests. http://stackoverflow.com/questions/1428431/switch-off-case-sensitive-urls-in-google-app-engine/1429800#1429800 -Nick On Wed, Sep 16, 2009 at 3:40 PM, johnc ogmani...@gmail.com wrote: We recently moved our company website to Google app engine.
