#summary Using dbmapper from Grails
#labels Featured,Phase-Deploy

= Introduction =

If you follow the GORM rules for tables in your database, this should work great.

= Install the plugin =

`grails install-plugin dbmapper`

= Generate the classes =

`grails generate-domain-classes`

This will create JPA domain classes in your `grails-app/domain` directory along with a `hibernate.cfg.xml` file within `grails-app/conf/hibernate`.

= Modify your DataSource =

You need to modify your main DataSource definition to support annotated Hibernate classes:

`configClass = GrailsAnnotationConfiguration.class`
