Is there any ORM tools on google app engine (Java)?

Question

Hi, everyone. I used Ruby and Rails before, and I enjoy Rails's ORM, which make me develop application very fast... ...(also make me reduce lots of SQL statement.) But now, I need to move from ROR to Google App Engine. Is there any ORM tools on that? Also, I heart that Google have some amazing tools called "Google Web Toolkit", can I take advance of this tools within any setup? Thank u.

Answer 1

GWT is not a ORM tool by any stretch of imagination. You can check JDO or JPA for GAE applications built using GWT. My personal favorite is Objectify, a perfect balance between native API and JDO. YMMV

If you are not particular of language, have you considered Phython + Django?

Answer 2

JDO, JPA, Objectify, Slim3
