[appengine-java] Re: JDO not saved (commit) when using spring @ModelAttribute
Thanks for your response
But I didn't get any exception that the persistenceManager connection
is closed
It just didn't save without giving any errors
and persistenceManager's detachCopy also didn't save

[appengine-java] Re: Duplicate incoming emails?
Hi Ikai, Thanks for the follow up. I can't say for sure, and the following is my crystal ball guess of what's happening. The problem only occurred when I was developing my email webhook. It has since stopped happening (I think). When developing my webhook, often I had exceptions thrown as a result of not parsing the Multiparts correctly. On the surface, it looks like when an exception is thrown, the email is marked as undelivered and AppEngine retries to send again later. This is further complicated when on some requests, I was processing a plain text email as a MultiPart email, which resulted in OutOfMemoryErrors. Due to the high CPU usage, AppEngine temporarily shuts down my app. Not sure what happens next, but it would appear the SMTP server retries whilst my app is down/suspended or otherwise broken and ends up failing to deliver each time. Something gets out of sync then, because it would build up a backlog of failed deliveries and retries for each failed delivery! The other side effect was my app would never stay up - AppEngine would restart it and then it would immediately get shut down again (due to the high CPU usage from the OutOfMemoryErrors). Once I fixed my code, I noticed lots of repeated emails coming through (and getting processed/saved to the datastore). I let it run for several hours for it to clear the backlog of emails. It has since stopped delivering these dups. Does this make sense? Plausible? Prior to using AppEngine's inbound mail funtionality, I was using http://smtp2web.com which had a nice feature in that if an exception is thrown when calling the webhook, it would send a bounce email to the sender and stop trying. This was nice I thought because there was user feedback that the mail didn't get through. Your thoughts? dave AppEngine may opt to suspend the app (eg due to high CPU usage). This in turn could be signalling to the SMTP server that the mail delivery has failed and signal it to try again later. However, what gets placed in the queue may be a duplicate, so there might be a reference to two copies of the same email that needs to be delivered. After a certain timeout, AppEngine restarts the app, which fails to restart properly because it immediately fails again due to the email resend. This is further complicated if a new version is deployed with changes to the email webhook - so some requests would succeed and others fail.

Diana, I cannot talk for Google but I suppose you cannot _require_ as an obligation that Google fixes your own bugs. If Dimitry is able to identify a bug in GAE, he should point it out and the GAE folks will address it. Other than that, you are subject to a "bona fide" effort, which may not be what you are looking for. In that case, you should look for paid support (there are third parties that offer such services).

Re: [appengine-java] Re: Duplicate incoming emails?
Interesting. This is great information and gets us that much closer to being able to deterministically reproduce the error. I'm pretty sure I've seen this before myself, but it was a one off issue. I'll see if I can reproduce this. On Thu, Nov 19, 2009 at 12:50 AM, Dave Cheong wrote: > Hi Ikai, > > Thanks for the follow up.

[appengine-java] Velocity Template reading error : java.security.AccessControlException: access denied (java.io.FilePermission
Hi to all,
i'm try to use Apache velocity template for mailing,
using the following code
VelocityEngine ve = new VelocityEngine();
try {
ve.setProperty("resource.loader", "file");
ve.setProperty
("file.resource.loader.class","org.apache.velocity.runtime.resource.loader.FileResourceLoader");
ve.setProperty("file.resource.loader.path","/template/email/");
ve.setProperty( RuntimeConstants.RUNTIME_LOG_LOGSYSTEM_CLASS,
"org.apache.velocity.runtime.log.Log4JLogChute" );
ve.setProperty("runtime.log.logsystem.log4j.logger",
log.getName());
// ve.setApplicationAttribute
("javax.servlet.ServletContext",this.servlet.getServletContext());
ve.init();
} catch (Exception e1) {
// TODO Auto-generated catch block
log.warning("EI:"+e1.getMessage());
}
VelocityContext context = new VelocityContext();
Template template = null;
try
{
template = ve.getTemplate("mail1.vm");
}
.
But at runtime gives this exception :
11-19 10:44AM 33.316 [wincheck123/4.337839622240022599].:

Are there some security configuration to set for reading files on
appengine? such as security policy or others
Thank in advance

Re: [appengine-java] Re: GAE status / availalbility problems?
Nacho, I don't want to argue either side, but there are some gray areas: in this case, the feature that we tried to use wasn't supported, but I don't believe that it is clearly documented, nor the behavior of the APIs and the web interface were exactly helpful for developers. Whatever the application does, ideally it should not lead to the admin console crashing with HTTP 500 error code. If it is crashes, it is clearly a bug on GAE side - but is it critical/blocking, if we know what caused it to be surfaced and we know alternate approach? Definitely no. The same is about exception APIs returned when we tried to query those objects from the DB: was the exception very helpful? No. But thanks to Jason from Google, we found out the reason for the exception and worked around, so our problem was solved although of course again - not informative exception is a bug in API (just as the fact that some objects can be stored but not retrieved), and ideally it should be fixed in future, but it's not blocking to us. My point is, there are bugs on GAE side, but I don't have expectations that all of them will be fixed - I hope just that those which cannot be reasonably worked around, will be fixed :) On Thu, Nov 19, 2009 at 1:20 AM, Nacho Coloma wrote: > Diana, I cannot talk for Google but I suppose you cannot _require_ as > an obligation that Google fixes your own bugs. > > If Dimitry is able to identify a bug in GAE, he should point it out > and the GAE folks will address it.

Re: [appengine-java] Re: Can't send mail with attachment using JavaMail API
Looks like you're right. As far as I know there are no hidden methods.
Another workaround for this limitation could be to store incoming images in
the data store on an incoming email, then reference them in the emails that
get sent out. It's not ideal, but it may be the solution to what you are
looking for.

Re: [appengine-java] Re: NullPointer on key
What you'll want to do is to retrieve the object before closing the PersistenceManager and storing it into request scope. That is: PersistenceManager pm = PMF.get().getPersistenceManager(); MyUser u = pm.get // .. some retrieval code; u.getContactInfo(); pm.close(); We'll be changing this behavior in an upcoming release so that embedded objects, text, blob and list fields that are not retrieved by default will be retrieved on a fetch.

[appengine-java] Re: Can't send mail with attachment using JavaMail API
Any chance to see this bug fixed in the future ?
Is there any documentation on the meaning of "Converting
attachment data failed" error message ?

By the way, do you know if Google plans to open source some parts of
GAE librairies so we could investigate deeper when we encounter such a
problem ?

[appengine-java] Re: Problems with large request/response headers
Correct I do not see this problem on the production cloud. I've entered a bug report as requested: http://code.google.com/p/googleappengine/issues/detail?id=2413 One other point... Although Jetty issue #336 says that it was fixed in 6.1.11, I still see the problem when using "standalone" Jetty 6.1.16 unless I add: 8192 to jetty.xml. So perhaps simply upgrading the Jetty that is bundled with the GAE SDK won't be enough. Perhaps the fix for #336 was to allow the headerBufferSize configurations to be honored??? In which case we'd need both a newer Jetty in the GAE SDK *plus* the ability to configure it.

Re: [appengine-java] Re: Can't send mail with attachment using JavaMail API
We'll always try to open source what makes sense. I'm not sure it'd make
sense to open source all GAE libraries since many of the calls talk to
services. The javax.mail.* could fall under the "makes sense" category.

Re: [appengine-java] Forcing a redirect to the actual Google Accounts screen?
What are you trying to do? Your development server would not be able to use the session that is created from the actual Google Accounts screen. If you really needed to, you could probably implement the UserService interface and dependency inject the implementation you need to return the real login URL or the stub when you need that. As of right now it's: https://your_app_id.google.com/a/DOMAIN.COM (can be gmail.com) I wouldn't rely on this since it would change, which is why we provide a service for retrieving it.

Re: [appengine-java] bulkloader dump and restore
Len,
I assume you are doing this by having different application versions for a
Python application and Java application as documented here:
http://googleappengine.blogspot.com/2009/06/10-things-you-probably-didnt-know-about.html
Then redefining your Java data class in Python in your Exporter class and
passing a string similar to this to appcfg.py:
appcfg.py --server=python.latest.YOURAPPID.appspot.com download_data APPDIR
--filename=output.csv --kind=Thing --config_file=APPDIR/thing_exporter.py
There's a trick you'll need to export the key. Here's my Thing.java (
http://pastie.org/706983):
import com.google.appengine.api.datastore.Key;
import javax.jdo.annotations.*;
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class Thing {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key key;
@Persistent
private String name;
@Persistent
private int number;
public Thing(String name, int number) {
this.name = name;
this.number = number;
}
public Key getKey() {
return key;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getNumber() {
return number;
}
public void setNumber(int number) {
this.number = number;
}
}
Here's the corresponding Python exporter code (http://pastie.org/706981):
from google.appengine.ext import db
from google.appengine.tools import bulkloader
class Thing(db.Model):
name = db.StringProperty()
number = db.IntegerProperty()
def AddKeys(entity_generator):
for entity in entity_generator:
entity['key'] = entity.key()
yield entity
class ThingExporter(bulkloader.Exporter):
def __init__(self):
bulkloader.Exporter.__init__(self, 'Thing',
[('key', str, None),
('name', str, None),
('number', str, None)
])
def output_entities(self, entity_generator):
bulkloader.Exporter.output_entities(self, AddKeys(entity_generator))
exporters = [ThingExporter]
The magic here is in the AddKey that you define. You add the "key" field to
the objects in each iteration of your loop exporting an entity.

[appengine-java] convert JDO query to JPA
hi all,
i have a JDO query that i would like to port to JPA.
Friend Entity
@PersistenceCapable(identityType=IdentityType.APPLICATION)
public class Friend {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key key;
@Persistent
private String lastName;
@Persistent
public int crud;
@Persistent
private String firstName;
@Persistent(defaultFetchGroup = "true")
private Collection friends;
//JDO
javax.jdo.Query query = pm.newQuery(Friend.class);
Key myKey = user2.getKey();
query.declareParameters("com.google.appengine.api.datastore.Key
myKey");
query.setFilter("friends == myKey");
query.setOrdering("crud ASC, lastName ASC, firstName ASC");
List friendList = (List) query.execute(myKey);
The problem i am having is with the query.setFilter("friends ==
myKey" ) portion.
//JPA
javax.persistence.Query query = em.createQuery("select from
Friend where friends=:key");
query.setParameter("key", user2.getKey());
List friendList = (List) query.getResultList();
however the resultlist returns 0.
any help is appreciated
