[google-appengine] MVC framework
Hi All, What is a good java MVC framework to use in GAE development. I use GWT for most stuff, and servlets and JSP's. But, doing simple things in GWT is more time consuming. For more complex forms and UI logic, I will still do in GWT I am looking for a java MVC framework with good UI components for rapid web development. I have worked few years ago on Struts and little bit on JSF. I am not in favor of Struts for now. I am not sure about the JSF community and its support now. I have gone thru the group and found few * vRaptor * Slice * Wicket etc. What is currently used by the developers? It should be easy to learn, and a lot of documentation to get started. -Aswath www.AccountingGuru.in -- You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Re: MVC framework
We have a few GWT Project Templates, building something rapidly is very straightforward. I don't think it will be easier with other frameworks such as Wickets. They also don't perform very well on GAE. Op donderdag 20 december 2012 11:17:06 UTC+1 schreef aswath het volgende: Hi All, What is a good java MVC framework to use in GAE development.

Re: [google-appengine] Re: Send SMS from Google appEngine using java
First time on www.parseco.com I did get some 'money' to account. I don't remember how much exactly. 7.5€ ? (10$). Try to sign. I don't know if this will be automatically. Tropo's team was very supportive for route to my country but now they have some problems with it so I can't use it. Twillio had some small glitch during their conference time and I am using them as backup route. Parseco/Infobip is my primary sms gateway. I didn't have problems with them and their programming support was very fast. At first they used some GAE non-whitelisted classes and one hour after my contact they changed lib and pushed changes to git so I was able to use it's java client instead of rest api. Tropo and Twillio are USA providers with global coverage. Parseco/Infobip is global provider with offices around the world ( http://www.infobip.com/about/worldwide_locations/). This could be reason why they have (maybe) better quality global coverage. You need to try it to be sure for your country.

[google-appengine] Re: Transient error when attempting to add task to queue; fails on retry
I had some TransientError issues when using queues in iterative loops. The
fix (workaround) that has eliminated the issue was to nest the iterative
queue command inside a try/except. If there is a transient error, the
handler does one time.sleep(0.1) command, and retries. If the error
re-occurs, then the g.t. one sleep cycle error handling escalates. (And
yes, I really, really hated to do burn up 100 cpu millis, but was
desperate. Since TEs were infrequent, the overall resource waste proved de
minimus.) To date this has fixed my transient errors. Never have had a TE
outside of such loops. As with everything, YMMV. HTH -stevep

Hi all,
At the moment I'm getting TransientError exceptions whenever I try to add
a task to a queue in my Python app, using code like:
q = Queue('default')
q.add(Task(url=url, countdown=countdown))
It appears to be happening with every queue, every time--retrying doesn't
help. Has been going on for at least 30 minutes, and blocking important
activity on my site. I haven't done any deployments in the last 4 days; it
just started happening on its own.
This is happening in both my production app, premium-prod-hr and my
staging app premium-test-hr on site www.craftlaunch.com.
Anybody else seeing this? Any suggestions?
Thanks,
Scott

Yes, Steve this is good suggestion and standard practice but there was a real
issue that day that lasted for hours so these loops timed out.

[google-appengine] Re: How to change port for devserver
dev_appserver.py -p 8081 . If you use the appengine launcher to actually run your app, there is a spot I believe to add command line flags in the project settings. Running dev_appserver.py -h via the console will give you a good list of params too revealing some useful bits that are not widely known. ~Blaine On Tuesday, December 18, 2012 11:01:30 AM UTC-6, Jhonghee Park wrote: I am trying to switch from maven-gae-pluginhttps://github.com/maven-gae-plugin/maven-gae-pluginto appengine-maven-pluginhttps://developers.google.com/appengine/docs/java/tools/maven.

Re: [google-appengine] Re: Transient error when attempting to add task to queue; fails on retry
Hey PK,
Apologies if my reply suggested I was discounting everyone's recent
problems. (Also sorry to learn that my wasting resources solution is a
good standard practice.) I know many posts here are desperate attempts to
alert G. re:system issues. So many of late it has become hard to know when
to offer a design suggestion vs. staying quiet so as to let G. receive a
cleaner signal from the forum. -stevep

[google-appengine] legacy mapreduce library only running one shard
We are using the legacy (non-PipelineAPI) version of the mapreduce library: http://code.google.com/p/appengine-mapreduce/ The issue is that we can only ever get one shard processing, even for kinds that have 150,000 entities. We have tried different shard_count configurations, e.g, 4, 16, 128, but always only one shard processing entire dataset, which is very slow. I feel like I've missed a step (e.g., creating an index or something). Crossing my fingers that someone knows an offhand answer.

Re: [google-appengine] Re: Urgent, Need Help: Instances are shutting down after a couple minutes of inactivity.
Ready for this? Now, a single instance survives for hours and hours, happily serving requests with the usual low latency response time. This is just what Sir Brandon wrote about. Mysterious changes in the system's behavior. I should note that I sprinkled rainbow Skittles across the floor to attract the unicorns. They're back!

[google-appengine] idle/dynamic frontend instances not load balanced correctly
Hi, We have been using AppEngine for our production application for over a year now. We are taking little more trafic from last week. We found the number of front end instances that are spun do not follow a paatern. Set min idle instances as 3. We saw 3 resident instances as expected and 6 dynamic instances. But only 3 dyanmic instances took 99% of the requests. The other 3 dynamic instances took 10-20 requests in a day. We monitored the pattern for 3-4 days and we think something is not right.. If the requests are load balanced correctly, why 3 dynamic instances don't serve any requests? We get charged for all FE instances. We stopped the dynamic instances which were taking very few requests and after few mins we found new dynamic instance.. Are we missing anything?

[google-appengine] Illegal argument erros when fetching a object from datastore with primay key
Hi, We are using HR datastore for our data needs for our application. We had some promotions in our app which resulted in a big spike of requests. There were 25-30 req/sec and all requests were accessing datastore. We also use memcache as needed. All our datasore reads/writes failed with no clue on the exceptions. A simple read from datastore caused this exception. The application was down for couple of hours because of these errors. This seem to happen under load. Can anyone in appengine team what's the issue here? Says illegal argument and invalid handle. LogUtils error: Error in getting data from datastore javax.jdo.JDOFatalUserException: Illegal argument at org.datanucleus.jdo.NucleusJDOHelper.getJDOExceptionForNucleusException(NucleusJDOHelper.java:344) at org.datanucleus.jdo.JDOPersistenceManager.getObjectById(JDOPersistenceManager.java:1676) at org.datanucleus.jdo.JDOPersistenceManager.getObjectById(JDOPersistenceManager.java:1767) at org.datanucleus.store.appengine.jdo.DatastoreJDOPersistenceManager.getObjectById(DatastoreJDOPersistenceManager.java:73) NestedThrowablesStackTrace: java.lang.IllegalArgumentException: invalid handle: 14104995113016828271 at com.google.appengine.api.datastore.DatastoreApiHelper.translateError(DatastoreApiHelper.java:33) at com.google.appengine.api.datastore.DatastoreApiHelper$1.convertException(DatastoreApiHelper.java:70) at com.google.appengine.api.utils.FutureWrapper.get(FutureWrapper.java:94) at com.google.appengine.api.datastore.FutureHelper$CumulativeAggregateFuture.get(FutureHelper.java:142) at com.google.appengine.api.datastore.FutureHelper$TxnAwareFuture.get(FutureHelper.java:218) at com.google.appengine.api.utils.FutureWrapper.get(FutureWrapper.java:86) at com.google.appengine.api.datastore.FutureHelper.getInternal(FutureHelper.java:71) at com.google.appengine.api.datastore.FutureHelper.quietGet(FutureHelper.java:32) at com.google.appengine.api.datastore.DatastoreServiceImpl$1.runInternal(DatastoreServiceImpl.java:68) at com.google.appengine.api.datastore.DatastoreServiceImpl$1.runInternal(DatastoreServiceImpl.java:65) at com.google.appengine.api.datastore.TransactionRunner.runInTransaction(TransactionRunner.java:29) at com.google.appengine.api.datastore.DatastoreServiceImpl.get(DatastoreServiceImpl.java:65) at com.google.appengine.api.datastore.DatastoreServiceImpl.get(DatastoreServiceImpl.java:55) at org.datanucleus.store.appengine.RuntimeExceptionWrappingDatastoreService.get(RuntimeExceptionWrappingDatastoreService.java:56) -- You received this message because you are subscribed to the Google Groups Google App Engine group.
