问题


I try to build a very simple GAE application, using eclipse and the Google Plugin for Eclipse. I've generated some Endpoint from an @Entity class, then I've generated Cloud Endpoint Client library.

After that I've started the appEngine project (within eclipse, on the embedded jetty server). When I try to access /_ah/api I get the following issue:

HTTP ERROR 500

Problem accessing /_ah/api/. Reason:

Failed to retrieve API configs with status: 404

Caused by:

I was able to test in real device by setting --address=0.0.0.0 in run configuration.
