[appengine-java] Re: No API environment is registered for this thread
Thank you lp, and Didier. Actually this application will need to run in production, and not only in testing. I need to be able to update the application's datastore with a feed from Analytics. When I create a very simple GUI for it using GWT (basically just a submit button,) I get a timeout exception because the Analytics server takes too long to respond (it seems to be unsolvable at this point.) So I thought I'll just run it as a simple Java application -- and than I don't have the timeout problem and the Analytics feed works beautifully. But then -- this problem. When I create objects from the Analytics feed, and try to insert them into the datastore, I get the exception above. What am I missing? You help is greatly appreciated!

As you know, you can deploy many versions of an app for the same app id. There is nothing that says it has to be the same app. Just deploy another app that does your weekly updates using another version string. Each version, even though it may not be the default one, gets its own url. You just need to trigger it one a week thereafter.

Found a solution by using a different API:
MemcacheService cache = MemcacheServiceFactory.getMemcacheService();
Rest of the code is the same.
Actually documentation of app engine has some shortcomings on this
topic. I have passed 2 days trying to find a solution and finaly found
it in O'Reilly's book on app engine.

[appengine-java] Re: Task Queue on other App Servers
We use JDO on top of datastore and also on MySQL (for Tomcat for example). Had to work through a few limitations for complete JDO portability across both, but it works and we release and test same cide on mysql/ Tomcat also. Have to work on JMail setup on Linux when we get time for email sending portability, but don't expect problems. TaskQueue and XMPP are only services we don't have a portable solution to yet. -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
