[appengine-java] Re: generating sequence for persistence classes like Country and so on ...

2010-07-09 Thread Nacho Coloma

That seems like good advice. For this concrete use case there is a
country list included with your JDK:

Locale[] locales = Locale.getAvailableLocales();
for (Locale locale : locales) {
countries.add(new Option(locale.getCountry(),
locale.getDisplayCountry(currentLocale)));
}

[appengine-java] Re: Enabling SSL for a Servlet

2010-07-09 Thread l.denardo

Hello Ikai,
as I mentioned elsewhere in the group, access via HTTPS does not
complete properly.

What I get is an error

"Secure Connection Failed
An error occurred during a connection to ikai-openid-demo.appspot.com:
80.

SSL received a record that exceeded the maximum permissible length.

(Error code: ssl_error_rx_record_too_long)
*   The page you are trying to view can not be shown because the
authenticity of the received data could not be verified.
*   Please contact the web site owners to inform them of this
problem. Alternatively, use the command found in the help menu to
report this broken site."

This happens on Firefox 3.6.6 on Ubuntu 10.4, and happens at the time
I get redirected to the app after allowing the app to access my Google
Account information.
The same on Chrome with a different message.

Any pointer on this behavior will be very useful to me, since my app
is affected too.
Thank you
Regards
Lorenzo

[appengine-java] Re: Breaking change in data store?

2010-07-09 Thread Simon

I know that there was planned downtime yesterday (see
http://groups.google.com/group/google-appengine-downtime-notify if you
aren't monitoring it already) as part of their plan to try and fix
their datastore performance issues (mentioned here
http://googleappengine.blogspot.com/2010/07/upcoming-datastore-downtime.html).
It sounds to me like the problems your facing are very much linked to
these changes!

[appengine-java] Re: "The request is invalid for an unspecified reason."

2010-07-09 Thread Simon

What version of the SDK are you using?  I was under the impression
that the limit had been increased to 3000 files across the
application, with the following limits:

- 150 MB max combined size of code files
- 10 MB max individual size of any file
- 1000 files max per directory (not counting files in subdirectories)

Same on firefox and Chrome on OSX
Http works, https fails.

Also, is there source code available.

I can't find anything (for java) at:
http://code.google.com/p/google-app-engine-samples/
and appengine-java-sdk-1.3.5 seems not to have it as a demo.

Thanks,

Shawn

PS.  Actually Chrome reports:
Unable to make a secure connection to the server. This may be a
problem with the server, or it may be requiring a client

[appengine-java] How to handle simultaneous requests (for same action) ?

2010-07-09 Thread sree

sending request simultaneously with 15 seconds time interval for the
same action will throw an server error

for example
/generateReport.do?start=0&end=100

when request for /generateReport.do is sent every 15 seconds like

after 15 seconds: /generateReport.do?start=101&end=200
after 30 seconds: /generateReport.do?start=201&end=300
after 45 seconds: /generateReport.do?start=301&end=400
after 60 seconds: /generateReport.do?start=401&end=500

then the following message will be logged in the logs for atleast 2 or
3 requests.

Request was aborted after waiting too long to attempt to service your
request. This may happen sporadically when the App Engine serving
cluster is under unexpectedly high or uneven load. If you see this
message frequently, please contact the App Engine team.

how to handle the above condition ?

[appengine-java] Re: Frustrations with Performance

2010-07-09 Thread Jake

Hey all,

Any keepalive task has been discouraged by the AppEngine team.  At the
same time, they have also stated that even minor activity should keep
the application up and running for a longer amount of time - on the
order of an hour.  So, I simply hope to encourage them along that
second path :)

[appengine-java] Re: GWT Code works only in local env and does not work after uploading to App engine

2010-07-09 Thread Toby Reyelts

- Does the rest of your GWT UI show up fine?
- When you run with Eclipse are you ever testing the compiled production
(web) version of your app, or are you always running in development mode?
- Are you testing with the same browser against App Engine as you are
against Eclipse?
- You can try compiling your GWT app with -style PRETTY and using some
javascript debugging tools like Firebug.

You have an instance of the old version of that object serialized in one of
your HttpSessions. You need to discard that HttpSession from your datastore.

[appengine-java] Problem with wait and notifyAll

2010-07-09 Thread marios

Hi, this is my problem: my service has two synchronized methods. One
of them writes events and the other listens. This works well with GWT,
but does not work uploaded in GAE.

..
private UserData user = new UserData("mjs");
..

public void writeEvent(String event) {
synchronized (user) {
   user.getEvents().add(value);
   user.notifyAll();
}
}

public List readEvent() {

List events;

while (true) {
synchronized (user) {
if (user.getEvents().size() > 0) {
events = user.getEvents();
user.setEvents(new ArrayList());
break;
}
try {
user.wait();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}

return  events;
}

Error LOG:

I think user.notifyAll () will never "wake up" user.wait (), is that
correct?.

[appengine-java] new version problem

2010-07-09 Thread Jake Stayman

I just deployed a new version 1-1 of my application.  It works fine on
the local dev server, and uploads successfully.  But when I try to
access it at http://1-1.latest.appname.appspot.com, I get the
following message:

"Error: Server Error
The server encountered an error and could not complete your request.
If the problem persists, please report your problem and mention this
error message and the query that caused it."

How do I find out more about the problem?  Are there error logs
available?  When I look under "Admin Logs" and "Logs", there is no
indication that I even tried to access this new version of the
application.

Thanks for any help.

i am not sure what do you mean. Please clear.

Basically in the popup itself i fire a rpc call to get data from big table
and render it as a flex table.
this entire code is written in the constructor of the popup.

John,
thanks for your encouraging reply.
to make my question clear,

is it possible to send user input from an external site, to the java
application hosted in appspot and process the input and send the out put
back to the external site?

thanks a lot.

Re: [appengine-java] Re: achieving URL redirection (.htaccess) functionality with app engine?

2010-07-09 Thread Ikai L (Google)

GAE/J is just servlets, so in a sense, your opinion can be more accurately
described as believing it should be part of the servlet spec. Either way,
filters allow you to do this easily (as you can see from the project) and
offer more flexibility and testability over Apache mod_rewrite.

[appengine-java] How can i invalidate the session when user log in out from my app using the google log out link?

2010-07-09 Thread Daniel

Hi i got a JSF 2 web app, with the google login system, the thing is
that when the user click on the log out  (using the createLogoutURL
of the UserService class)

the session isnt being invalidated and the next user that doing login
from the same browser gets the previous user session.. and all the
data that was stored by the first user being seen by the next user

Maybe its possible to create a new session upon each user login...?


Any ideas?

Re: [appengine-java] Re: Breaking change in data store?

Hi Simon,

I wouldn't be surprised that it has to do with the changes made during
this downtime.

This being said, the downtime notice only mentions higher read/write
latencies, not changes in the data store behavior.

Someone from GAE team?

Re: [appengine-java] Re: Enabling SSL for a Servlet

2010-07-09 Thread Ikai L (Google)

I'm running OS X on my laptop. This works in Firefox 3.6 as well as Chrome
5.0.375.99.

Can you try this from the command line?

curl https://ikai-openid-demo.appspot.com

I'm wondering if there are weird settings at a lower level - for instance,
some weird proxy action going on, or a company network that chooses to
rewrite HTTPS (though I have never heard of this).

We can at least fix the "source code availability" problem:

http://github.com/ikai/App-Engine-Java-OpenId-Demo

(I also linked to it on index.html). My colleague Wesley is working on
publishing a very detailed article about OpenID, and this code was actually
stolen from him.

BTW - there is a known issue with HTTPS and OpenID. I was just using that

Re: [appengine-java] Re: Enabling SSL for a Servlet

2010-07-09 Thread Ikai L (Google)

Okay, I'm starting to realize what's happening here. We're all talking about
different things:

1. Original poster is asking about HTTPS and appspot in general.  This is
supporter

2. All of you with the issue with port 80 are reporting a known issue with
OpenID (http://code.google.com/p/googleappengine/issues/detail?id=3393). You
can try *any* appspot app besides my OpenID example with HTTPS. Here's one:

https://jspincludetest.appspot.com/repro

This is why it's important to include repro steps when reporting an issue. I
was completely confused.

Let's take the OpenID chatter to a new thread, since we've clearly resolved
any issues with HTTPS and appspot on this one.
