I'm using App engine JDO, for storing my data in database and I use 
appengine plugin for eclipse for deploying my application.

I created some bean classes and deployed. While deploying, I did not choose 
any version of DataNucleus JDO/JPA. It was empty as shown in the picture.

As a result, I could see my datastore kinds and entities got created with 
the strange casing, which was not same I named those. (Even I could find 
the same in development environment as well).

I have given my kind name as WorkUser, but it got created like WORKUSER (upper 
case), similarly, all field names, for eg., I created accessToken in my 
bean class, it got turned into ACCESS_TOKEN.

Although everthing works fine for some days, I wanted to migrate my JDO to 
JDO 3.0 and now, while deploying, I have chosen Datanucleus version to v2.

Did necessary configurations for migration. The issue I found now, is none 
of the entities are available to query from code. I could see all kinds and 
entities present in appengine console, but, when I'm trying to fetch the 
data, I'm getting empty results.

How can I make my data to be fetchable ?

Any help would be greatly needed and appreciated. Thanks.
