[appengine-java] Date, Calendar question (multiple instances of web application behaviour) clarification
Good day, I would like to ask about following. How is java.util.Date synchronized in case there is more than 1 instance of my web application. Example: WebAppInstance01 : I create somewhere new Date() at the same time WebAppInstance02: I create somewhere new Date() Is there some time shift ? Or those both app request some central authority ? Thank you, -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] is there any solution/idea how blacklist IP in realtime ?
Hello, I was looking for some solution which would allow me realtime blacklist IPs. I didnt find any. Realtime I mean without manually getting IP and change dos.xml and upload it. A man can upload dos.xml to bann certain IPs. Can this be done somehow (anyhow) programmatically, even using home computer ? I image it would be possible to let my computer run request every 5 mins to get webapplication abusive IPs and then upload new dos.xml ? Is this only possible solution or I am heavily missing something ? :) Other way I came with is to update dos.xml on gae webapp and somehow trigger it has changed so gae will notice, problem is I dont know how or if its even possible :) Thank you for you time, -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Re: Active transactions
Hi lisandrodc,
please carefully read all documents
http://code.google.com/appengine/docs/java/datastore/
and
http://www.datanucleus.org/products/accessplatform_1_1/guides/jdo/daolayer_design.html
Also many people cannot read spanish, if you would write in english
you may get more
answers.
I think you problem is that you datastore operation failed in catch
block
and since you are closing persistence manager first and then
rollbacking it
fails.
Solution:
1) read everything as carefully as possible, look at example and try
experiment.
2) in finally block rollback first and then close persistence manager

[appengine-java] error when persist more than 1 object
I am trying to learn GAE by writing simple java programs. This is the
coding I use to try JPA:
EntityManager em = null;
try {
em = EMF.get().createEntityManager();
int i = 6;
Trade5min t5 = new Trade5min();
t5.setStkCode(i);
t5.settDate(2010-07-15);
t5.setTradeRec(this is trec of +i);
em.persist(t5);
} finally {
em.close();
resp.getWriter().println(TestWrite done);
}
It works. I can see the persisted records in datastore, and showed
TestWrite done on the browser.
However, if I add a second persist:
EntityManager em = null;
try {
em = EMF.get().createEntityManager();
int i = 6;
Trade5min t5 = new Trade5min();
t5.setStkCode(i);
t5.settDate(2010-07-15);
t5.setTradeRec(this is trec of +i);
em.persist(t5);
i++;
t5 = new Trade5min();
t5.setStkCode(i);
t5.settDate(2010-07-15);
t5.setTradeRec(this is trec of +i);
em.persist(t5);
} finally {
em.close();
resp.getWriter().println(TestWrite done);
}
It gives out warning:
handleAbandonedTxns: Request completed without committing or rolling
back
and then PersistenceException: Illegal argument at em.close().
Anybody know what's wrong with my coding?

[appengine-java] Length of member variable names contributes to storage space used?
Hi,
I read in a post that the length of member variable names contributes
to the amount of storage space your app uses, example:
class Farm {
private String mFarmersFavoriteCropToPlant;
}
would take more space to store than:
class Farm {
private String m;
}
might not matter for a handful of instances, but if I have thousands
of records... is this true?
Thanks

I don't know if there are any differences, since I never tried the other way.

My 2 cents: if all your users are of type Person and it's a root entity, you can also save some space by storing Key ids instead of Key instances (you save the redundant type name etc).

[appengine-java] Re: java.net.InetAddress and logback 0.9.21
I'm running into the same issue (I'm using logback 0.9.21).
I tried to configure Logback manually using the JoranConfigurator.
Well, I started extending the JoranConfigurator trying to avoid the
call to the method ContextUtil.addHostNameAsProperty() in the
ConfigurationAction class that is the one causing the issue but it
looked I needed to extend a few classes and started to look messy.
At the end I took a different approach. Just created the ContextUtil
class in my webapp project in the same package as the original one so
mine would be picked instead of the other.
This is the code I put for that class ... (basically removing the use
of java.net.InetAddress class)
package ch.qos.logback.core.util;
import ch.qos.logback.core.Context;
import ch.qos.logback.core.CoreConstants;
import ch.qos.logback.core.spi.ContextAwareBase;
public class ContextUtil extends ContextAwareBase {
public ContextUtil(Context context) {
setContext(context);
}
/**
* Add the local host's name as a property
*/
public void addHostNameAsProperty() {
context.putProperty(CoreConstants.HOSTNAME_KEY, yourhostname);
}
}
Hope it helps.

[appengine-java] Re: Roo + GWT + Security on AppEngine
2) i had some issues with static files, spring security doesnt protect static html files. I do have similar problem. Spring security works pretty fine for me, but I cannot understand why I can't limit access to HTML host page. The current situation is that my application starts and I have to handle login problem in gwt code by myself. I'd prefer Spring security to handle this, so when user is not logged, and try to load my /Application.html, he/she is automatically redirected to login page, and no gwt entry-point code is launched until user is logged in. This behavior is working very fine for dynamically (by servlet) generated content (such as JSP pages), but the filter chain seems not to be applied to to static (e.g. HTML) resources. For example: When this is set in config file: intercept-url pattern=/secured/** access=ROLE_ADMIN / and I try to access /secured/administration.jsp Spring security rejects access correctly. But when I try to access /secured/index.html and the file exists, seems that no Spring filter chain is applied and the file is displayed. Is there a way how to configure Spring security to deny access to static files when user is not logged in? -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

an application(for example web). When close the persistence manager?
When commit the transaction? The pattern singleton the example?
Because if I continue the help of google, the pattern, close a
persitence manager, for example:
PersistenceManager pm = PMF.get().getPersistenceManager();
Employee e = new Employee(Alfred, Smith, new Date());
try {
pm.makePersistent(e);
} finally {
pm.close(); //I accede again for the system, it is going
to give mistake because it is closed
}
The standard errors that happen to me are:
1- Object whit id model.fe...@cf17c3 is handled for other
ObjectManager.
2-The persistent manager is closed.
3- The transaction is active still. You must close the transactions
using the methods
commit() o rollback().

[appengine-java] PMF.get().getPersistenceManager() freezes after restart
We are seeing some strange behavior... after we stop/restart the dev server it freezes when trying to get an instance of the PersistenceManager. Steps to repeat: 1) We execute a query similar to the AppEngine example: http://code.google.com/appengine/docs/java/datastore/queriesandindexes.html#Introducing_Queries 2) It returns about 480 entities 3) We stop the server using the Eclipse console 4) We restart the server and attempt to run the same Query 5) It hangs at PMF.get().getPersistenceManager(); We put in output statements to verify, and it doesn't output the second string and in firebug we just see the RPC request hang... System.out.println(getting PMF); PMF.get().getPersistenceManager(); System.out.println(got PMF); Has anyone experienced similar issues? We are running Eclipse Helios with AppEngine 1.3.5, GWT 2.0.4, JDK 1.6_20 and the newest Google Eclipse Plugin. We tested on Ubuntu and Windows 7 and got the same results. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

From your eclipse itself(having an older version of gae), you can update to latest version by using software updates option in elclipse.

I can get the basics working, however I run into problems when I want to transfer (trade) an existing Player instance to an existing Team instance. Outside of that relationship, the objects are completely different. I have the problem that a child cannot be moved because apparently it isn't in the same entity group.

[appengine-java] Re: Length of member variable names contributes to storage space used?
Hi Mark,
I would say yes: the datastore viewer shows the data with couples
(name,value), name being the origianal attribute name in the java
class.
Moreover the doc says Each persistent field of the class represents a
property of the entity, with the name of the property equal to the
name of the field (with case preserved). at
http://code.google.com/appengine/docs/java/datastore/dataclasses.html#Class_and_Field_Annotations

Hi,
I read in a post that the length of member variable names contributes
to the amount of storage space your app uses, example:
class Farm {
private String mFarmersFavoriteCropToPlant;
}
would take more space to store than:
class Farm {
private String m;
}
might not matter for a handful of instances, but if I have thousands
of records... is this true?
Thanks

distance, ObjectToSave.class, baseQuery, pm);
Assert.assertTrue(objects.size() 0);
} catch (Exception e) {
// We catch excption here because we have not
configured the PersistentManager (and so the queries won't work)
}
} finally {

[appengine-java] Tag clouds on GAE for Java - how to store and how to aggregate
Hi, I'm looking to store entities using GAE Java which have 1-many tags. I would like to display a tag cloud, so will need to know how many times each tag occurs (can't use aggregate functions and group by on GAE to do this like I would in SQL). And when I click a tag I would like to retrieve all entities with the selected tag. Does anyone have any examples of what my Classes should look like to do this optimally and efficiently? Sample JPA code would be great too. Cheers - Jonathan -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[google-appengine] Re: How logging [doesnt?] work?
The listed behavior seems to work in production only. I haven't been able to write output on standard streams in development too. Anyway you can simply log the required output with the appropriate log level, and it will be prompted to your console if logging properties are correctly set.

[google-appengine] Subcategory Capability with GAE Datastore Models?
Hi! I've been recently trying to wrap my head around GAE's datatypes. Is there a model type in GAE that allows me to define subproperties? For example, I want to have a category property where some categories fall under others, and when i query for all entities within a supercategory, i get the subcategories also. For example: class Animals(db.Model): type = db.StringProperty() Animals(type='mammal') Animals(type='chimpanzee') Animals(type='monkey') When I query for all animals with type mammal, i want to return all 3 of the above objects. I've read through the documentation, and the PolyModel datastore model has struck my eye as being potentially helpful. However, it doesn't seem to quite do the job.

Re: [google-appengine] Subcategory Capability with GAE Datastore Models?
As you said, you can accomplish this using PolyModels, eg:
class Animal(db.polymodel.PolyModel):
...
class Mammal(Animal):
...
class Chimpanzee(Mammal):
...
class Monkey(Mammal):
...
and retrieve all Monkeys, Chimpanzees and other Mammals using:
animals = Mammal.all().fetch()
OR you can roll your own by using a ListProperty (or a StringListProperty),
eg:
class Animal(db.Model):
type = db.StringListProperty()
animal1 = Animal(type=['mammal'])
animal2 = Animal(type=['mammal','chimpanzee'])
animal3 = Animal(type=['mammal','monkey'])
db.put([animal1,animal2,animal3])
and retrieve all three using:
animals = Animal.all().filter('type = ','mammal').fetch()
I'm sure there are other solutions to this too.

[google-appengine] Re: Subcategory Capability with GAE Datastore Models?
you can achieve this in polymodel by adding all common properties to polymodel base class and specific property to the hierarchy. i.e. Class LivingThing(polymodel.PolyModel): Kingdom = db.StringProperty() Phylum = db.StringProperty() Subphylum = db.StringProperty() Class Mammal(LivingThing): noofbreast = db.IntegerProperty() class Monkey(Mammal): canjump = db.BooleanProperty() now you can create class monkey as, Monkey(Kingdom=Animal,canjump=True) and later query as LivingThing.filter(Kingdom =,Animal).fetch() can return Monkey.

[google-appengine] Are key filters more efficient than ancestor queries?
Imagine the following models:
class Parent(db.Model):
name = db.StringProperty()
count = db.IntegerProperty()
class Child(db.Model):
number = db.IntegerProperty()
value = db.StringProperty()
Whenever a new Child is added, it is added with a Parent as its parent
entity in a transaction which also updates some values on the Parent.
My question is this: To get a list of children that belongs to a
Parent, is it more efficient to add a ReferenceProperty to the Child
model and filter by that, than it is to use the ancestor filter in
queries?
To clarify in code:
# Using ancestor
Child.all().ancestor(parent_key).fetch(10)
# Using filter on a new ReferenceProperty called 'my_parent'
Child.all().filter('my_parent', parent_key).fetch(10)

These two should have roughly the same performance.
Bear in mind, though, that if you don't need entity groups for transaction
purposes, you should avoid using ancestor relationships. Given that, the
second approach is a better one - just not for query performance reasons.

[google-appengine] Re: Are key filters more efficient than ancestor queries?
Thanks Nick.
The reason I use entity groups is not for any kind of performance
reasons – I really need to make sure that the Parent entity is updated
in combination with a Child entity being added, and the values being
set are related to the order of entity insertions, so entity groups
feel like the right thing to do to ensure data atomicity.
My only thought is that I'd rather add redundancy (by adding a
ReferenceProperty that can be inferred from the key) than lose
performance. If the performance difference is negligible however, I'd
rather not add an unnecessary property.

[google-appengine] Does anyone have a code example of AES encryption in python?
Hi, I have a query string I need to encrypt using AES in CBC mode with zero padding, before finally encoding it to base64 and I need to run this on Google App Engine in Python. I've had a look around and can't be sure what works in GAE and what doesn't, I'm also finding it hard to get example code of some of those I believe should work, such as (http://code.google.com/p/slowaes/). Does anyone have a code example or link to one for AES encryption in python on Google App Engine? I think AESSlow seems to be the one to use with App Engine but can find no examples of how to implement it.

App Engine status has bench marks for this,

But I can tell you for your situation here the get would be ideal
because you would actually be using 4 queries because thats what the
IN clause does behind the scenes, and thats the way your query would
work with the id == 'id1' || id == 'id2' ...

You want the batch version of the get function,

which shouldn't involve multiple round-trips to the database.

Re: [google-appengine] Re: Are key filters more efficient than ancestor queries?

On 19 July 2010 13:26, Blixt andreasbl...@gmail.com wrote:
Thanks Nick.
The reason I use entity groups is not for any kind of performance
reasons – I really need to make sure that the Parent entity is updated
in combination with a Child entity being added, and the values being
set are related to the order of entity insertions, so entity groups
feel like the right thing to do to ensure data atomicity.
My only thought is that I'd rather add redundancy (by adding a
ReferenceProperty that can be inferred from the key) than lose
performance. If the performance difference is negligible however, I'd
rather not add an unnecessary property.

Imagine the following models:
class Parent(db.Model):
name = db.StringProperty()
count = db.IntegerProperty()
class Child(db.Model):
number = db.IntegerProperty()
value = db.StringProperty()
Whenever a new Child is added, it is added with a Parent as its parent
entity in a transaction which also updates some values on the Parent.
My question is this: To get a list of children that belongs to a
Parent, is it more efficient to add a ReferenceProperty to the Child
model and filter by that, than it is to use the ancestor filter in
queries?
To clarify in code:
# Using ancestor
Child.all().ancestor(parent_key).fetch(10)
# Using filter on a new ReferenceProperty called 'my_parent'
Child.all().filter('my_parent', parent_key).fetch(10)
These two should have roughly the same performance.
Bear in mind, though, that if you don't need entity groups for
transaction
purposes, you should avoid using ancestor relationships. Given that, the
second approach is a better one - just not for query performance reasons.

For example, static files: “App Engine serves static files from separate servers than those that invoke servlets” http://code.google.com/appengine/docs/java/gettingstarted/staticfiles.html Now its your proxy that is serving those static files, unless you use different URL schemes for files. So if app engine has edge caching or a CDN for those files, you will not benefit from it. It is also unclear whether DOS attack will take into account proxied IPs (set in X-Forwarded-For header). Whether it is or not, you need to handle DOS attacks on your proxy yourself. In other words, proxying diminishes some of the advantages of using app engine over other hosting options. So the real solution is that google supports HTTPS by allocating IPs to customers that opt in (as opposed to TLS). -- You received this message because you are subscribed to the Google Groups Google App Engine group.

Re: [google-appengine] Domain name management
check your DNS if www.xxx.org pointed (as CNAME) to ghs.google.com. you can check via dig or nslookup.

[google-appengine] CPU Time / cpu_ms and api_cpu_ms
hi, i'm pretty new to the app engine and encountered some problems on which i've not been able to find any information. i've created a test application fetching some webpage and parsing the result into the datastore. here i see a big difference in the cpu time which i am not able to explain. i've been trying to profile the complete parsing without revealing any clues. this is the log entry /parse 200 5019ms 47102cpu_ms 46500api_cpu_ms 16kb AppEngine-Google; (+http://code.google.com/appengine) having the following internal result PUT cost -643 megacycles for loop number: 100 complete cost (including PUT) -724 megacycles for a total rows of 100. the script does nothing else but fetching a page (including 100 rows), parsing the information and batch inserting it into the datastore. is there any information available how to improve this behavior, or if im doing something i should not do? thanks a lot and with best regards gordon -- You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Data Migration
Hi, I'm trying to build a commercial application but I'm pretty stuck on an approach for data migration between versions of my application. I found this thread which seems to have ended in 2008. Any updates from Google on this? Any ideas? http://groups.google.com/group/google-appengine/browse_thread/thread/af31f013857f36ae# -- You received this message because you are subscribed to the Google Groups Google App Engine group.
