I'm currently wondering how it is possible to use the Groovy ORM Layer from Grails standalone outside of the Grails Framework. There is a Documentation Entry for doing so, but the ZIP file only links to an empty page. I downloaded Grails 1.2-M3 but I couldn't find anything in the docs either.
Does anybody know what the current state is and how to accomplish this?
As of Grails 2.3.6, GORM is officially supported as a standalone module. See the release notes for more details.
AFAIK it is possible to use GORM standalone since Grails 1.1. This allows you to use GORM as your ORM without using the full Grails framework
However, I don't think it's possible to use GORM outside of Spring (which is the foundation on which Grails is built). To summarise:
A sample application demonstrating how to use GORM outside Grails is available here. If you want to browse the source code of this example in a browser (instead of checking it out from the SVN repository), start here.
