[appengine-java] GAE response returns null randomly
Randomly the response is coming as null although the required DB save/Update is successful Scenario: I am using Rest web services(Restlet) for client-server communication 1URLFetchService as client (as HTTPClient is not supported) URL url = new URL(http://localhost:8080; + path); URLFetchService urlFetchService = URLFetchServiceFactory.getURLFetchService(); HTTPRequest httpRequest = new HTTPRequest(url, HTTPMethod.POST); httpRequest.setPayload(payload.getBytes()); resp = urlFetchService.fetch(httpRequest); 2Sending the data as an XML and on the server side unmarshalling it using JAXB. 3After saving/updating the JDO , i am returning an appropriate status message as a Representation in response. e.g - new StringRepresentation(User already exists., MediaType.TEXT_PLAIN); The problem is that many times the response is coming as null even though an status with a proper Representation is returned. I came to many assumptions to justify the above issue 1May be the URLFetchService times out (as i read somewhere that it times out in 5sec) 2The web layer calling REST services the app layer responding are on the same GAE server. Also tried using urlFetchService.fetchAsync().. Struggling with this issue for past one week Any insights...Please update Thanks Sri -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Re: Creating/Compiling new Java class at run time
I'm not sure about the idea. Sounds like giving a rocket launcher to a kid. You let the adaptation happen in the full development environment made for professional programmers. If the re-deployment does not work out, will your framework reset the GAE invisibly to the user? And so on. Then there is this UI you made that I presume limits what the user can specify quite a lot. So you could instead make a GAE application that receives the settings from the UI and makes the appropriate brancings accordingly. Like you write a program that adapts it behavior depending on some parameter file, just that the parameters comes from the UI. Besides, I think that dynamic classloading is not possible in GAE. /J On Mar 7, 9:13 am, Rick Smith rick@gmail.com wrote: Hi all Can I create and compile a java class at run time on goolge appengine.

for the example given regarding group count. 1.student market is incremented from 16 to 17 and saved() 2.the incremented value 17 is passed to 2 task queues . 3. each task queue has this checkingmarker.sequence [from marker.get() ] = sequence [from value passed in through task queue] if before reach step3, we do another update on student and marker and sequence is now incremented to 18 and follow by step 3 is run we will have17 = 18 arent this will break the consistency of the data. as now task queue no longer able to execute task as marker.get() will be value 18,19,20 , but the first task sequence number is 17 not yet execute and cannot execute as marker.get() return 18 ? is this the reason Brett mentioned transaction must be 1 transaction/s to minimize this from happening? -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Is there any gurantee task set (A, B) will be execute before task set (C, D) ? because task queue wiki mentioned there is no guarantee for the sequence of execution . if this ordering is not gurantee, in mean in high load side, if task C and D are executed before task A, B. data consistency has problem.

Hi, You're right: you can't control WHAT (size, etc...) the users upload but you can control IF they upload: the key after /upload is generated by App Engine and has to be a valid one (not too old, not used yet, etc,,) to be usable for an update. If you generate such an upload for authentified users, it gets pretty secure. What else you be looking for ? If it size, or content or something equivalent that means anyway that you have to get out of the browser sandbox in your application (via java applet, etc..) in order to do the additional controls you need: a regular web app can't access and check local files because of the sandbox. regards didier On Mar 11, 12:07 pm, Luca Matteis lmatt...@gmail.com wrote: I have started using the Bloblstore Java API:http://code.google.com/appengine/docs/java/blobstore/overview.html It seems like the upload form goes to something like: form action=/_ah/upload/agRtaWx1chsLEhVfX0Jsb2JVcGxvYWRTZXNzaW9uX18YTww This is part of appengine, it's not my code.

[appengine-java] Re: Remote_api in Java works in Development Server?
Carlos, I am having the same problem. This is a huge issue with the Google App Engine. I chose this environment to develop on because it seemed to be flexible and robust. The prices seem fair. To not be able to develop on a local development platform in Java is a deal killer. I'm at my wits end. I'm using a large data set and need to test things locally first. That there is no easy way to ingest data locally is absurd. I recommend you give http://appwrench.onpositive.com/ a try. You can upload data, but it's a bit buggy.

[appengine-java] Blobstore API vs Datastore API
After spending almost half a day implementing the Blobstore API locally I realized only after uploading that it actually to have billing enabled in order to work. I'm not exactly happy with that because I wish the dev_appserver would've told me. Anyhow, I don't feel like giving out my credit-card to Google for this feature since I just want to test my little project and how it behaves, performance wise, with Google's free option. So after googling a bit I found this: http://stackoverflow.com/questions/1513603/how-to-upload-and-store-an-image-with-google-app-engine-java Which basically uses the datastore to store a Blob of the image. I'm wondering, if this is possible, why is Google charging for the Blobstore API? -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Luca, If you're compiling from Ant, why can't you just make that task also ping the server or touch appengine-web.xml? We don't think of the aforementioned solutions as hacky.

Yes, but not if you want to allow uploads. If you enter your credit card, we will not charge it unless you go over the free quota, even for blobstore.

You'll want one that is embeddable - i.e. designed to be run as a library as opposed to just standalone. What language are your custom business rules written in?

Sounds like giving a rocket launcher to a kid. You let the adaptation happen in the full development environment made for professional programmers. If the re-deployment does not work out, will your framework reset the GAE invisibly to the user? And so on. Then there is this UI you made that I presume limits what the user can specify quite a lot. So you could instead make a GAE application that receives the settings from the UI and makes the appropriate brancings accordingly. Like you write a program that adapts it behavior depending on some parameter file, just that the parameters comes from the UI. Besides, I think that dynamic classloading is not possible in GAE. /J On Mar 7, 9:13 am, Rick Smith rick@gmail.com wrote: Hi all Can I create and compile a java class at run time on goolge appengine.

[appengine-java] Re: Blobstore API vs Datastore API
Hi Luca, 1 thing before going in the new code: by using the blobs in datastore, the interactive time limit (30s) apply (it does not for the blobstore) I.e., the upload must be finished in 30s after that request is cancelled by gae.

Re: [google-appengine] 2 project talk internally with each other
Hi Jimmy, If you need two apps to communicate, your only real option is to write some type of service. You might want to evaluate your reasons for using two separate apps though. Using two apps will probably add significant complexity (and possibly latency!) to your app. If you need to do this, look at the URL Fetch API. if you're using Python: http://code.google.com/appengine/docs/python/urlfetch/ if you're using Java: http://code.google.com/appengine/docs/java/urlfetch/ Robert On Thu, Mar 10, 2011 at 03:01, Jimmy Au ji...@mesixty.com wrote: How to do internal communication for 2 project and url rewrite stuff inside google app engine? -- You received this message because you are subscribed to the Google Groups Google App Engine group.

I'm running into an exploding index problem because I need to be able to query by a composite index on two list properties (owners_saved and topics)...both list properties can potentially become really long.

[google-appengine] High CPU Warning - Is it really an issue?
Hey, I recently finished my app and have since began testing. One of my main resources makes 14 RPCs, I have made every effort to decrease CPU time I.e. marking properties as unindexed, however I really cannot reduce the number of GETs, PUTs and queries that occur in the request. The average CPU times associated with the request today is: ms=381 cpu_ms=1192 api_cpu_ms=1122 cpm_usd=0.033597 This does fluctuate and can be less, however it rarely falls low enough to have the high CPU warnings removed. I've noticed my app still scales fine, I have about 15 instances running whilst testing. So my question is, should I be concerned at the high CPU warnings or is it something most people experience?

[google-appengine] High-level development tools for App Engine?
Hi there, I'm running Google Apps Premier for a small (healthcare) business. We are looking to expand over the next twelve months and will be considering a database solution to help us improve our current methods of storage and management of our client clinical records. As there isn't a cost-effective ready-made solution for us, I would like to consider developing a solution under the Google Apps Engine, as a possible option. Can anyone suggest a development tool(s) which I could consider for the Google Apps Engine whilst I have a software engineering background, I would prefer not to have to do too much coding as there is much I currently have to focus on in running the business itself. The solution from SalesForce (Force.com) is the sort of development level which would be manageable for me. I would prefer to use Google Apps to host the solution as the integration will likely be tighter, and will also be far more cost effective for us.

Re: [google-appengine] Help against GFW!
I really doubt that GAE will be available in China any time soon. I remember the time Google search engine showed filtered results on its Chinese version, and now google.cn is not existing anymore, since Google did not want to obey to the communist government policies, which contradict basic values and rights. Nothing seems to change in this regard. You are quite brave in exposing the CCP crimes, and keep doing that for the good of your people, but keep safe since they can take your life literally. But I guess you know that already.. I would not put my hopes in an external government these days, since they all seem quite corrupted.

maybe some usefull tips http://code.google.com/p/relat/wiki/gaetips 2011/3/10 Mark Spencer m...@theotcentre.co.uk Hi there, I'm running Google Apps Premier for a small (healthcare) business. We are looking to expand over the next twelve months and will be considering a database solution to help us improve our current methods of storage and management of our client clinical records. As there isn't a cost-effective ready-made solution for us, I would like to consider developing a solution under the Google Apps Engine, as a possible option. Can anyone suggest a development tool(s) which I could consider for the Google Apps Engine whilst I have a software engineering background, I would prefer not to have to do too much coding as there is much I currently have to focus on in running the business itself. The solution from SalesForce (Force.com) is the sort of development level which would be manageable for me. I would prefer to use Google Apps to host the solution as the integration will likely be tighter, and will also be far more cost effective for us. Any help would be gratefully received -- You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Re: Problems copying entities to the high replication datastore.
I found my workaround. I used the appcfg bulk loaders to accomplish what I needed. I just did a appcfg.py download_data on each of the kinds from the source app. Then I did appcfg.py upload_data to target app and all of the entities got transferred successfully. For the entity type that was about 2GB of data it took about an 1hr 20min to download and about 3 hours to upload. The good news also is that it only cost me $7 in CPU to upload.

This is a quirk of shell.appspot.com. I've not dug into the code, but perhaps it is something to do with how the session context updated and stored.

Re: [google-appengine] Re: task chaining why set taskname?
I have to echo Ikai's sentiments on this. I've used Fantasm to put together some semi-complex workflows very quickly (within a couple hours of looking at Fantasm). It is definitely easy to pickup and start doing something productive. Very nice work Jason Shawn. That said, Brett's Pipeline API has some awesome capabilities. If you spend the time to learn it, you'll be able to put together very powerful workflows. If you're already familiar with 'yield' semantics, you will get the idea quickly.

[google-appengine] 'NoneType' object has no attribute 'active_jobs'
Hi Everyone,
I am using App Engine 1.4.2 (1.4.2.1041) in Python.
I noticed a new error message in my logs. It shows up every hour at
26 minutes past the hour. Also, when I got into my App Engine
dashboard, the Datastore Admin section doesn't work (it's just
blank).
I tried re-installing App Engine but it didn't seem to help. Has
anyone else seen this error before?
The logs say:
2011-03-11 14:26:16.196

Re: [google-appengine] Re: High CPU Warning - Is it really an issue?
lp, If you haven't already, you might want to use Appstats to verify that the variations are not actually caused by RPC calls. Always on doesn't mean you'll never get a loading request; instances have to be started, which will be a loading request. If you get enough traffic to need additional instances you could see loading requests (they are indicated in the logs).

Re: [google-appengine] Re: High CPU Warning - Is it really an issue?
There are a couple of things you can still do: - Try always to send high expensive operations to the background (task queues). And also an expensive operation does not mean a lot of processing time in your side. If you notice your API CPU usage is high, this could be a delete/put operation on an Entity that has, either many indexes, exploding problems or data contention due to a not well designed entity group. A simple delete/put could take a lot of time or create a bottleneck in your application. - Don't burst out the task queue operations, play around with the Stored Task Queue bytes and tasks execution rate, try to find the limit of tasks per second for a operation before it creates contention problems. Doing so, we were able to diagnose the limits on terms of request per second of our system (protecting it by task queues) and now we take those alarms as new designs we need to apply for that specific resource to consume less and split it in different executions. Just to give you a reference, we load tested a resource pretty much in the same conditions as yours, and we are able to scale it 10x times what it does right now before the serving cluster warned us with throttling. But dont take this as a this would go beyond, i would not worry but as a notice to keep looking for new designs/architectures.

Re: [google-appengine] Re: Where can I find commercial successfully websites created using GAE?
all those sites/apps looks great! quite amazing. I see GAE as an emerging platform, the fact google is exposing via API or modified solutions of their own infrastructure have a lot to think about. The occasional hiccups are because of the same emerging platform that has to deal with all our/business ideas that sometimes creates new problems (as technology should).

[google-appengine] Re: Solutions to an Exploding Index Problem
Hi Aaron, Your may roll down Keywords model to KeywordsOwnerTopic: class KeywordsOwnerTopic(db.Model): owner_saved = db.ReferenceProperty() #though I prefer to use StringProperty and store key_name, and query by it topic = db.ReferenceProperty() sort1property = db.IntegerProperty Does original Keywords store some more data? Then you may avoid duplication by referencing to it: class KeywordsOwnerTopic(db.Model): owner_saved = db.ReferenceProperty() #though I prefer to use StringProperty and store key_name, and query by it topic = db.ReferenceProperty() sort1property = db.IntegerProperty() keywords_ref = db.ReferenceProperty() #Keywords model key class Keywords(db.Model): some_other_data = db.SomeProperty() ... Also if you querying some model only by properties, not the keys/ key_names, you have an option to store short data (500 bytes) in key_name (+ adding some unique number as prefix) and querying with keys_only=True - this will be much faster This may be used E.g. if Keywords particular entity represent only one keyword, and its length 500 (may be I misunderstood your data model though) Best regards, Den On Mar 11, 11:23 pm, Aaron aaron.t.che...@gmail.com wrote: Hi Jay, Exactly, I need to query for keywords based on user and topic.
