Is it possible to generate class domain from existing database schema?

Hello
I want to know if it's possible to generate my domain classes from an existing database schema with grails?

Best regards

Use the http://grails.org/plugin/db-reverse-engineer plugin. Make sure to use v0.3 for Grails 1.3 and v0.4 for Grails 2 as described in the docs.

I have tried this plugin on 2.0.0 RC3. Any pointers will be helpful..

Set the configuration etc in Config.groovy and running the 'grails db-reverse-engineer', I get the following error:

log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment).
log4j:WARN Please initialize the log4j system properly.
