[appengine-java] how to encrypt a blob before uploading via blobstoreservice
hello together, i read and tried the following codepart out of the google.code... (http://code.google.com/appengine/docs/java/blobstore/overview.html) with the given code out of this example the upload of the blob happens immediately after clicking the submit button. i want to encrypt the file to upload before it will be saved in the storage via BlobstoreService.createUploadUrl().

Re: [appengine-java] How do you transfer a ListJdoObject from server to client?
All you need to do is put this code in a servlet and then call the servlet
as the button's action. Having said that is always good to learn the basics.
Here is a link for app engine JDO implementation :
http://code.google.com/appengine/docs/java/gettingstarted/usingdatastore.html.
The easiest way to learn JDO is to use the sample app. called guestbook and
see how it works.
Best of luck.

Hello,
I have been wanting to know how to do this for a while now, but don't know
where to find information on how to do this. I simply want to know how to
setup my project so I can have a JDO object in the server package (so I
can use classes like com.google.appengine.api.datastore.Key and
javax.jdo.listener.StoreCallback), and request a list of those objects from
my client side code. Currently I store my JDO object in my client package.
So when a user clicks a button to retrieve all the People objects I can get
back a ListPeople. I'm sure these are some fundamentally basic steps I
just don't know to acheive. Do you need a persistent object on the server
side and a transfer object on the client? If so how do you send the data to
the transfer object. Thanks
currently have: (and want it instead in com.myapp.server but also to
retrieve say ListPeople )
in com.myapp.client

Re: [appengine-java] Re: Eclipse hangs at startup, Ubuntu
Yeah, it is only a guess that the version control plugins are causing some sort of interference. Sorry that you had to go through this. The changes in GPE 1.3 should alleviate this issue.

Do you have any version control plugins installed in Eclipse? We've actually made some changes so that the update of war/WEB-INF/lib occurs on classpath change instead of classpath init.

[appengine-java] Forwarding a request to a external URL preserve IP - Can it be done?
Hey, Is there a method in which I can receive a request and then forward the same request to an external URL (not redirect)? Importantly, the IP address of the device which made the initial request MUST be preserved. It must look, to the external URL, that the request came from the device which made the initial request and NOT from the app engine. The reason I need to do this is the external URL returns data whose representation changes regularly. My app engine application will parse this data and return it to my Android application in a format it expects. So is this at all possible?

[appengine-java] CPU Limits using App for large scale processing
I've got a large computational problem that can be done in small chunks 10sec and where the data required for each portion of the simulation is very minimal. What I was hoping to do was dump a whole bunch of tasks in a Task Queue and then let the app engine scale up so that it can tear through that queue. Unfortunately i'm running into a problem where if i let the queue run too quickly then my log fills up with stuff like Request was aborted after waiting too long to attempt to service your request. Most likely, this indicates that you have reached your simultaneous dynamic request limit. This is almost always due to excessively high latency in your app. Please see http://code.google.com/appengine/docs/quotas.html for more details. I have a paid account, so it seems that from the quota documents I should be able to consume 72 CPU-minutes/minute - yet when i look in my dashboard it rarely gets much about 3 cpu-seconds/second. Unfortunately if I put shorter requests in the queue then i run into the limit of 20 queue requests per second, and it's more efficient for me to keep my requests in the 10 second range. What's the best way to make this consume more resources at a higher rate? thanks, Graham -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

where copy creates a new SubEntity and copies all fields except the

Re: [appengine-java] Re: Expires header automatically added (bug?)
Browsers use the expires header in conjunction with a URL locally to determine whether or not to request a resource. If this has expired or does not exist, browsers will then do a conditional get. The web server will return a 304 response if the resource has not been modified, so this will add additional latency to overall page load performance. You can validate these assertions using the Firebug and the web developer plugins for Firefox. In general, the rule is to not use Etags: http://developer.yahoo.com/performance/rules.html I'll follow up to see if the same restrictions apply on App Engine. My gut feeling is no, because we probably have some consistent way of generating the Etags, but I can't say with any certainty just yet.

[appengine-java] Performance Issues
I'm having a Google App Engine account for my applications, and I'm also an administrator of an application which was not created under my account. The application that was not created under my account (but for which I'm an administrator) doesn't have much traffic yet, but when it goes live will probably have a few thousand requests per day. For now we are having a cron job running every minute to keep the application alive. But most of the time the cron job is not running on time. There is a red message that displays that the job was run 5 seconds or more too late. Even some cron jobs fail. With no traffic to my application (only the cron job running) the graph on my dashboard isn't a nice flat line with an average of 1 request per minute (0,0167 requests per second). We see a lot of peeks going from 0,005 to 0,02 requests per minute. When I deploy the same application on my own account (greated a new application in my account but deployed the same webapp), the performance is like I would expect. With no traffic and only the cron job running we get a nice graph with 0,0167 requests per second. The line is almost flat and no cron jobs are running late. Even no cron jobs fail. Also for simple request I see a performance difference between the two applications. I'm having a also a high CPU job that I need to run. This work am I doing with queues. When I execute the work in both applications, the slow application can only execute 3 to 4 tasks per minute, with the other one can run the same task with the same data 5 to 6 times a minute. I would expect that both apps would behave in the same way and almost no notable performance difference, but this is clearly not the case. Is anyone having the same issue? What can be done about this? How can I increase the performance of the slow running application? -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Google Plugin for Eclipse 1.3 Preview is now available
Hi everyone, Last month, I announced some of the changes we had planned for the 1.3 version of the Google Plugin for Eclipse. To recap, this release is focused on making life easier for developers using GWT/App Engine alongside third-party tools, including Maven and Eclipse for Java EE. In my post, I promised we'd let you download a preview of 1.3 to get some hands-on testing of the new features and provide us with your feedback before the official release. I'm happy to announce that the time has come. An early preview of 1.3 is now available for download at the following URLs: http://dl.google.com/eclipse/plugin/3.5/zips/com.google.gdt.eclipse.suite.e35.feature_1.2.101.v201003031407.zip http://dl.google.com/eclipse/plugin/3.4/zips/com.google.gdt.eclipse.suite.e34.feature_1.2.101.v201003031407.zip http://dl.google.com/eclipse/plugin/3.3/zips/com.google.gdt.eclipse.suite.e33.feature_1.2.101.v201003031407.zip Note: Ensure that your version of Eclipse has Eclipse's Web Standard Tools (WST) installed before installing the plugin. WST can be installed by navigating to the Software Installation section, and selecting the the appropriate WST feature from the update site for your version of Eclipse. The update sites and feature names are provided below: - 3.5 (Galileo): Galileo Web, XML, and Java EE Development Eclipse Web Developer Tools - 3.4 (Ganymede): Ganymede Update Site Web and Java EE Development Web Developer Tools - 3.3 (Europa): Europa Discovery Site Web and JEE Development Web Standard Tools Project This is a preview build, so the usual caveats and warnings apply: it is not officially supported, and we recommend using a clean installation of Eclipse and a new workspace. Also, we're distributing this preview as a zip file so be sure to follow the instructions on our Installing the Google Plugin for Eclipse from zip files page ( http://code.google.com/eclipse/docs/install-from-zip.html). *Known Issues* - If you change settings in the Server or GWT tab in the launch configuration dialog, you'll need to switch to the Arguments tab before clicking Apply or Run/Debug. This will be fixed in the final release. That being said, we are very interested in your experience with this new release, which we hope will allow the Google plugin to interoperate much better with alternative project structures and third-party tools. The tentative 1.3 release notes are as follows: Enhancements - Configurable WAR directory to allow better integration with Eclipse for Java EE http://www.eclipse.org/downloads/moreinfo/jee.php and projects built with Maven http://maven.apache.org/ - Web Application launch configurations now display and allow editing of generated Program and VM arguments - Errors/Warnings preference page for customizing the severity of any generated problem marker - Projects can reference GWT/App Engine SDKs directly via JARs instead of through SDK library - GWT+App Engine projects automatically configured for optimal caching Fixes - GWT Issue 3583http://code.google.com/p/google-web-toolkit/issues/detail?id=3583: Google Eclipse Plugin configuration is too strict - GWT Issue 3592http://code.google.com/p/google-web-toolkit/issues/detail?id=3592: Eclipse plugin to add 'cache forever' configuration for new 'GWT + App Engine' projects - GWT Issue 3902http://code.google.com/p/google-web-toolkit/issues/detail?id=3902: Allow users to configure the severity of problems reported by the eclipse plugin - App Engine Issue 1515http://code.google.com/p/googleappengine/issues/detail?id=1515: Eclipse plugin requires fixed location for war directory - App Engine Issue 2115http://code.google.com/p/googleappengine/issues/detail?id=2115: Using the @PersistenceAware annotation puts the Eclipse Enhancer in an Infinite Loop - App Engine Issue 1941http://code.google.com/p/googleappengine/issues/detail?id=1941: Plugin fails to enhance dependent classes on source level changes For a complete list of fixed issues, see the GWT issue trackerhttp://code.google.com/p/google-web-toolkit/issues/list?can=1q=label:GPE_1_3 and App Engine issue trackerhttp://code.google.com/p/googleappengine/issues/list?can=1q=label:GPE_1_3 . We encourage all interested developers to take the preview build for a spin, and let us know what you think. We'll do everything possible to incorporate your feedback before the final release, slated for later this month. Thanks!

[appengine-java] Re: Performance Issues
Join the google dosent care about app engine performance club. To see how much google dosent care just check out their own app engine status page. http://code.google.com/status/appengine Isnt it funny how google lectures the whole world about how the web should be faster? Also some things you can do do fix performance to make it as slow(fast) as google app engine will allow. Override the DataStoreService interface making your own version that logs each round trip to a console output. This will help you learn how many round trips your making to datastore. Also google discourages cron pinggers but with them not providing a decent solution who can blame you.

There is a red message that displays that the job was run 5 seconds or more too late. Even some cron jobs fail.

Re: [appengine-java] Re: Enable billing to avoid HardDeadlineExceededError?
Hi Wong, I had this problem a while back when I was doing some intensive computations in my code. Eventually the entire app would become blocked for some minutes. The limit for API CPU is a lot higher than for CPU usage in your own code. I didn't come up with a solution to the problem - I am waiting for inspiration to figure out a more efficient algorithm. BTW, the daily CPU quota you increased is different from the per minute quota that you are running into.

[appengine-java] Re: Enable billing to avoid HardDeadlineExceededError?
No, the 30 second limit is a hard limit. If a request can't finish in 30 seconds (or somewhat earlier), you get an exception. You then have an undetermined amount of time before the app engine kills your request and returns a 500 status code. You wouldn't happen to be using Spring, would you?

Okay, the first thing mentioned was that you are using Spring. We are doing an experiment removing Spring in our app to see what impact it has on startup time.

[appengine-java] Multiple transactions at the same time
I was hoping to have several transactions going at the same time and
if anything failed in anyone of them, then I could roll back all of
them.
I set up some code to do this, looks something like the code below,
there may be some other problems, but the one that I see is that what
if there is an Exception thrown in the loop where I commit the
transactions, then I've already committed some of them, but not
others? Is this not something that I should be doing? If not, how
should I handle this sort of situation?
VectorTransaction txnVector = new VectorTransaction();
DatastoreService ds;
Transaction txn;
try{
ds = DatastoreServiceFactory.getDatastoreService();
txn = ds.beginTransaction();
txnVector.add(txn);
ds.put( entity, txn );
ds = DatastoreServiceFactory.getDatastoreService();
txn = ds.beginTransaction();
txnVector.add(txn);
ds.put( entity2, txn );
}
// ROLL BACK IF THERE IS A PROBLEM
catch( Exception e ){
for( Transaction txn : txnVector ){
if( txn.isActive() ){
txn.rollback();
}
}
}
// COMMIT ALL
for( Transaction txn : txnVector ){
if( txn.IsActive() ){
txn.commit();

If I initialize the 96 integer property columns that I defined with a default value of zero (default=0), then everything works fine - the datastore viewer and the query in my application work as expected. I will post a better set of information on this shortly. What I experienced was actually easily reproducible in the development environment. It was almost as if the model was forgetting about the null (None) columns, since they were so far to the right of the row. As if they were not there. So, initializing to zero made sure that there was something there (as if it were a placeholder almost.)

[google-appengine] HTML Django
Hey everyone,
I am currently working with a section of a site that takes user
input using Django forms:
description = forms.CharField(widget=forms.Textarea(attrs={'rows':
'10', 'cols': '80'}))
The only problem however is that this ignores any html tags that are
added in by the user and just prints them along with the text entered
in by the user. For example, a user may type in The quick brown fox
bjumps/b over the lazy dog, with the word 'jumps' intended to be
bold, but the html tags are just printed a long with the text. Is this
because I am possibly using the wrong widget? Any feedback is greatly
appreciated, thanks!

[google-appengine] -- App Engine Question
Hi All! I'm new to AE and was doing a bit of reading on the service. I was surprised to find that AE does not support websockets? whats up with that :). I have a framework that I've built over the last two years that depends on streaming connectivity. I HAVE read XMPP is supported by AE, and that lead me to a few questions that I cant seem to find the answers to - hence this post :) . 1. I have read that there is a max number of simultaneous connections. Does this apply to idle connections via NIO , where in they do not consume resources while waiting for a push, or does every connection hanging in suspension count? 2. Has anyone here had any problems with XMPP on AE? 3. Is there anyway to suspend the connection for streaming over XHR that I have overlooked? I have read that long polling is supported now.

Re: [google-appengine] server error on random occasions
Nick, The server error occurs when I try to load any of my three main (simple) jsp pages (no database access etc). The error is not repeatable and the app works fine now. The error occurred twice this week. And once it was loading just fine for me but for a friend of mine based out of a different city it just conked out and gave the server error message. I checked the request logs in the admin console and it does not show me any errors. Plus my code is peppered with try catches that would take me to an errorpage :). Would an exception cause such an erratic behavior. Would it not at the least be a bit more consistent. Any inputs will be greatly appreciated.

[google-appengine] Re: Proximity search
Thanks for all the answers. I was reading allot about geoshashing, but unfortunately the PubSchools demo uses a python implementation of geohash and there is no such port for java. I found a class http://code.google.com/p/javageomodel/source/browse/trunk/geocell/test/com/beoui/utils/HowToUseGeocell.java that is the java version of Geohash, but it has limited functionality. For an example, you can only search in square and not in circle like the radius search I am talking about, but it is still a solution and I have to manually create the square lat and long.

Re: [google-appengine] -- App Engine Question
Hi Robert, I've read on Jean-Francis' blog that his new project Atmosphere https://atmosphere.dev.java.net/ would work on App Engine. Also the Servlet 3.0 spec has asynchronous comet built in. Not sure if thats an option with AE yet. I wonder why XMPP lags? I have noticed this on EVERY XMPP app and code example that I have seen to date. Thats why I specifically asked about performance :). I just wonder if it's the protocol's much redundant overhead data being gziped causing decompression woes (the bends) on both ends? or perhaps the libraries. Though there are many of them and I doubt all back up under load. Have you noticed CPU spikes correlated with traffic at a disproportionate ratio? -- Thanks for the response.

[google-appengine] 1500 ms query latency
If you monitor App Engine Status you will notice that query latency has been floating around 1500 ms today. How can we deliver a product on top of app engine with this dismal level of performance? Google are you going to fix this issue anytime soon? I would appreciate if you treated these performance issues with the same level of concern as an outage.

Eli,
Python as usual is sooo much more elegant than java.

Either way, it seems that for this test, the effective Limit was 16
simultaneous accesses. As soon as I modified my code to try 17, it started
throwing a few Dynamic Request Limit errors.. though, the Logs page
AppEngine just refers to it as another Request (with code 500 and a time of
10 seconds).
Here is the code for the handler.. after receiving a GET, it sleeps for 3
seconds and the responds with a 'hello':
from google.appengine.ext import webapp
from google.appengine.ext.webapp.util import run_wsgi_app
import time

debug = True)
def main():
run_wsgi_app(application)
if __name__ == __main__:
main()
And here is they python code I am running on my local machine to test. It
fires off 17 threads. Each thread requests a GET from the handler and
prints the response, three times in a row:
import httplib
import threading
class meThread(threading.Thread):
def run(self):
for i in range(3):
conn = httplib.HTTPConnection('datastoretester.appspot.com')
conn.request(GET,/test/meTest?id=%s % self.getName())
response = conn.getresponse()
print response.read()
conn.close()
for i in range(17):
meThread(name=str(i+1)).start()
As soon as I scale the range back to (16), no more Dynamic Request Error.
Special notes: I am not sure if there is some sort of built in
rate-limiting for requests from the same IP address.. but when sending 17
threads at the handler.. it is not responding in 3 seconds to their GETs..
It takes about 11 seconds.
If you look in the Logs, for a run with 17 threads, you see this:
03-02 08:31PM 00.384 /test/meTest?id=16 200 12855ms 19cpu_ms 0kb gzip(gfe)
03-02 08:31PM 01.266 /test/meTest?id=7 200 11973ms 19cpu_ms 0kb gzip(gfe)
03-02 08:31PM 01.283 /test/meTest?id=15 500 10017ms 0cpu_ms 0kb gzip(gfe)
03-02 08:30PM 58.280 /test/meTest?id=4 200 11952ms 0cpu_ms 0kb gzip(gfe)
(Notice the 500 error in there as well.. that's the one that mentions the
Dynamic Request Limit).
Now, if I run the test with only 4 threads, it looks nice and quick like
this:
03-02 08:35PM 25.602 /test/meTest?id=1 200 3009ms 0cpu_ms 0kb gzip(gfe)
03-02 08:35PM 22.637 /test/meTest?id=2 200 3008ms 0cpu_ms 0kb gzip(gfe)
03-02 08:35PM 22.623 /test/meTest?id=3 200 3009ms 0cpu_ms 0kb gzip(gfe)
03-02 08:35PM 22.603 /test/meTest?id=4 200 3008ms 0cpu_ms 0kb gzip(gfe)
Once I start testing with more than 4 threads, it starts to slow down in its
response time...
So, I'd guess something would need to be clarified.. is there some internal
limiting going on per ip address? Does a long running process have a
lower simultaneous request limit?

Re: [google-appengine] -- App Engine Question
Hello i wanted to use xmpp on GAE but i stopped it becouse i read about the 30 maximun concurrent requests.But i see that you have used it.So how many concurrent users alow GAE in your app.? Thanks 2010/3/3 Richard Corsale richardcors...@gmail.com Hi Robert, I've read on Jean-Francis' blog that his new project Atmosphere https://atmosphere.dev.java.net/ would work on App Engine. Also the Servlet 3.0 spec has asynchronous comet built in. Not sure if thats an option with AE yet. I wonder why XMPP lags? I have noticed this on EVERY XMPP app and code example that I have seen to date. Thats why I specifically asked about performance :). I just wonder if it's the protocol's much redundant overhead data being gziped causing decompression woes (the bends) on both ends? or perhaps the libraries. Though there are many of them and I doubt all back up under load. Have you noticed CPU spikes correlated with traffic at a disproportionate ratio? -- Thanks for the response.

I have read that there is a max number of simultaneous connections. Does this apply to idle connections via NIO , where in they do not consume resources while waiting for a push, or does every connection hanging in suspension count? 2.

[google-appengine] mystery datastore entry
Hello, I have a strange problem occurring in my datastore's User class. class User(db.Model): user_id = db.StringProperty(multiline=False) When a user uses our app for the first time, an entry is written to this class like so: user = User(key_name=user_id) user.put() Where user_name is a unique string given to us by Mixi (the social networking site hosting our app). This is working for over 100,000 users, but we have 1 user that can't write to this table. For some reason, this one user id is not allowed. When trying to write the put for this 1 user, an error is generated. Querying for this user_id in the datastore gives no results. Doing a put with the same user id in our test version app works fine. If anyone has an idea what could cause this, please let me know.

[google-appengine] filtering a query returns nothing
Hi,
I'm trying to apply a simple filter to a query. When I do this
however, the query sees to be cleared, regardless of my filter's logic
I have an class 'c_portfolio_item' with a db.StringProperty called
category
I've verified that the categoryfield on all of my data is Sketch but
for some reason, doing this:
query = c_portfolio_item.all()
query.filter('category =','Sketch');
causes my query to return nothing
I've tried reversing the logic of the filter but it still empties the
query
I've also tried other query functions like order and they have the
same effect
I'm really stumped on this and would really appreciate any help or
ideas
I'm using django via the django patch for gae

[google-appengine] Map a Struts Action as welcome file in App Engine
Hi, I've been trying to have my landing page be displayed through a struts action but App Engine just wouldn't let me do it. The traditional way is to specify a .jsp in the welcome-file tag and the use jsp:forward login.do (just a quick example). This doesn't work. Next, I tried calling welcome-filelogin.do/welcome-file - doesn't work. Next, I placed a dummy file 'login.do' and used the tag welcome- filelogin.do/welcome-file - Doesn't work (this works on jBoss and this is how I usually use welcome-file to call a struts action). Is there a way to have a struts action as the default action to be called when users land on my site? Currently, I'm forced to do a redirect, which is ugly. So, my site http://justunfollow.com redirects to http://justunfollow.com/login.do , Please help me figure out a way! -Nischal -- You received this message because you are subscribed to the Google Groups Google App Engine group.

Re: [google-appengine] Re: 1500 ms query latency
I've been having trouble with exceedingly long queries as well...I've noticed that on a good day it appears that a query is taking 500 milliseconds. I have one or two complex requests that make several queries and that adds up quickly. Caching has helped immensely, but if data frequently changes it doesn't help much...

We are seeing the same on the app we are developing, along with long cold startup times the last few days (which otherwise had improved greatly after the downtime).

How can we deliver a product on top of app engine with this dismal level of performance? Google are you going to fix this issue anytime soon? I would appreciate if you treated these performance issues with the same level of concern as an outage. I have spent the past five months developing my app. http://code.google.com/status/appengine/detail/datastore/2010/03/03#a. .. -- You received this message because you are subscribed to the Google Groups Google App Engine group.
