Re: [appengine-java] elegant way of implementing sequence generator
Hello Ikai, I am interested in Sequences, sequence starting from a initial value and increments. Can you little bit elaborate here on what is the risk with volatile here when using memcache.

Re: [appengine-java] Re: Database cursor for back cursor?
How many pages do your users really want to see? Even Google search sets a limit - I think 1000 results. Although the number of results can exceed 1000 the offset is still limited so you would need to filter out results to continue past 1K. That would be slow. If you really need to return more than 1000 results and access them in forward and backward directions you could sort them by __key__ or some other unique combination and use that as you own cursor. You could define both ascending and descending indexes on your chosen property(s) to let you iterate in both directions.

[appengine-java] Re: Spring 2.5 Transactions - anyone got this working?
Hi Objectuser, Thanks for the suggestions. Pointcut is correct (I think so - keep second guessing myself though trying to implement this). I changed the domain to something generic when posting the example. Can you please confirm the following is correct, ie that you inject the proxy into the transaction manager. bean id=txManager class=org.springframework.orm.jdo.JdoTransactionManager property name=persistenceManagerFactory ref=persistenceManagerFactoryProxy / /bean The Spring 2.5 reference documentation in section 12.3.4 (http:// static.springsource.org/spring/docs/2.5.x/reference/orm.html#orm-jdo) has only the persistence manager factory. But it looks to me like it not in the context of using the proxy for transaction management. Some operations will work if I only inject the persistenceManagerFactory but then some will not (however all fail for testcases) I cannot get a testcase to work using spring managed transactions. Interestingly if I inject just the persistenceManagerFactory into the txManager bean some operations work but no testcase will work. Setting up testcases for the datastore is a real pain and I have followed the directions as per the google doco. Will try taking out the close methods and see if that makes a difference. Will keep bashing my head against this appengine wall. Cheers, Carl. On Mar 31, 2:10 pm, objectuser kevin.k.le...@gmail.com wrote: Check your pointcut ... is com.myapp.dao... correct? If that's correct, then I don't see anything amiss; it looks really good. Are you even able to setup a test where it works? Or are you doing it from a test? Oh, and check the use of pm.close(). That should be taken care of bySpringI think. I don't do it in my app anyway.

[appengine-java] blobstoreService.getUploadedBlobs() returns null from deployed GAE app, but works in dev server
I'm building an android app that posts a picture to a GAE web service.
I created the web service and tested it with a simple HTML form to
submit a picture and a few other fields. This works perfectly. I then
implemented everything for the android app and posting the image with
the other form data to the web service works fine when testing against
my local GAE dev server. When I test against my deployed GAE app, I
get a NPE when trying to retrieve the blobkey for the request.
The android app first obtains the URL that it can post to (I use a
HttpGet to do this). Once it has the post URL, I create a
HttpURLConnection based on that and write the image and the form
fields.
Has anyone run into this?

Re: [google-appengine] Re: Accessing the datastore remotely with remote_api
That post is actually somewhat out of date, as there's now a native Java remote_api client: http://code.google.com/appengine/docs/python/tools/uploadingdata.html#Setting_Up_remote_api(see the tip in that section for details).

[google-appengine] How to generate a random session ID etc.?
Hi, I have a short question on a security aspect. To generate something like a session ID or other random strings that need to be secure and unpredictable, I would use a code like this one: # start of the script (will be called 1 time when instance is loaded?) import os import random import string random.seed(os.urandom(24)) # later in the code class Test(webapp.RequestHandler): def get(self): topsecret = u''.join([random.choice(string.digits+string.uppercase+string.lowercase ) for c in range(16)]) Is this secure? Or is topsecret predictable if you know previous values of topsecret that were generated by the same instance? -Ulrich -- You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Google App Engine Supported Language
Hi I am new to Google App Engine. I know it is impossible for one to expect the App Engine to support all languages like C, C++, PHP, Perl etc etc. I would like to know why currently only Perl and Java is supported ? By only supporting Python and Java it is implicitly trying to ask developers to learn the above 2 languages exclusively. I have no arguments against Java but choosing Python over others make me wonder. Perl is quite established in it's own right so why didn't it make it into the list ? Python whitespace is getting on my nerves. I admit I am biased to Python due to my Perl leanings but shouldn't such an excellent language like Perl be considered to be on par with Python ? I don't want to start a flame war. I am just curious on the choice made to use Python instead.

Hi, sohguanh! I think that GAE developers (Google) think that Python is better for this task -- building sandboxed run-time environment. And may be Python is better than Perl in other cases.
