The Google AppEngine development server simulates Google's backend database with an embedded database. It creates a file on you local disk that you can delete to clear the DB. Is there a tool that allows to browse and edit this data, similar to the Data Viewer that you get for deployed applications?
Clarification: I am asking about the Java toolkit, not the Python one.
You can find it at http://localhost:8080/_ah/admin. Looks bit different, but provides the same functionality (apart of some bugs).
But in the light of OP question amendment this answer is not relevant anymore.
Yeah, I'm looking for the same thing. Looks like the URL doesn't work for the Java version.
Finally, data viewer comes with Google App Engine Java SDK version 1.2.2. It can be accessed at:
http://localhost:8080/_ah/admin
or
http://localhost:8888/_ah/admin
The same link as in Python version.
On my system (sdk 1.2.8 I think) the dev server runs on port 8888. So the data viewer is at http://localhost:8888/_ah/admin
