How can I use grails domain classes (which is in groovy) in service layer which is in Java/Spring.

When using the grails MVC, everything is fine as I can use controller to access domain objects and call CRUD and other dynamic methods on them. But, what I am wondering is is there a clean way to do it from Java - say the service layer. For example, I may want to develop a reporting framework where I need to use domain objects to access the DB.

I Hope the question is clear. This should be a standard problem that everybody must have faced in a reasonably sized project. I am just wondering how it is solved..maybe I am missing something here.

thanks.
