How to install JPA persistence provider in spring roo project?

Question

Hi guys! I am looking SpringSource Tool Suite with Google Integration and I am getting that hint when I define persistence setup.

hint:"Command 'persistence setup --provider DATANUCLEUS --database HYPERSONIC_IN_MEMORY' was found but is not currently available (type 'help' then ENTER to learn about this command)"...

and help is saying that: * persistence setup - Install or updates a JPA persistence provider in your project

how can I install JPA persistance provider to my project?

Answer 1

Have you tried with another provider? i.e for Hibernate it would be something like:

persistence setup --provider HIBERNATE --database HYPERSONIC_IN_MEMORY

I believe you can choose between ECLIPSELINK, HIBERNATE and OPENJPA.
