Re: [google-appengine] Google Cloud Endpoint initialization
Let me see if I understood correctly: are you saying a instance of my entire VM are launched every time a request is handled by the GCE engine? All my singleton classes (DAOs, default values, some utilities) are reinstantiated each request? I don't save sensitive state in memory (I use Memcache/Datastore for that), but some objects cloud be reused among requests, the way it works on regular GAE frontend requests.

Re: [google-appengine] Google Cloud Endpoint initialization
No. Instances don't get reloaded per request with Endpoints. That would be a terrible waste of resources. Sorry, I probably should have clarified/explained more in my previous email, but I was in a bit of a rush when I wrote that. Endpoints doesn't support static methods ( see this article, scroll down to the API Methods headerhttps://cloud.google.com/developers/articles/google-cloud-endpoints-for-android) unless they're marked as private. When OP tried to run his static method, it may not have run or failed off. In addition, I cheated a little bit on the answer and noted that the OP cross-posted his question to SOhttp://stackoverflow.com/questions/23123160/google-cloud-endpoint-initialization, where he said that he needed data tables precomputed during init. That's something that really needs to be moved to a regular cron or similar. @OP/Mike: Can you post a simple test case? - -Vinny P Technology Media Advisor Chicago, IL App Engine Code Samples: http://www.learntogoogleit.com On Thu, Apr 24, 2014 at 12:50 PM, Gilberto Torrezan Filho gilberto.torre...@gmail.com wrote: Let me see if I understood correctly: are you saying a instance of my entire VM are launched every time a request is handled by the GCE engine?

[google-appengine] Google Cloud Endpoint initialization
I have some initialization stuff that I'd like to do before GCE can be used. How would I do this? I tried creating a ServletContextListener and then calling a static method on my GCE but that doesn't work. In debugging I can see that the GCEs static variables are not set when a method is invoked. -- You received this message because you are subscribed to the Google Groups Google App Engine group.
