When you try JPA directly later, it would be nice to drop me a note with the result, perhaps on my blog / using mail. Thanks -stephan Hi Sam,

thanks for the feedback, I’ll try RC1 and see if it works. When you try JPA directly later, it would be nice to drop me a note with
the result, perhaps on my blog / using mail.

Thanks

I also just use the built-in Hibernate support rather than trying to call out to the EntityManager myself -- I'm still using GORM, just with my JPA based annotation classes rather than Groovy based GORM classes. The one thing I forgot to note here though is that you have to tell GORM about the annotations: import org.codehaus.groovy.grails.orm.hibernate.cfg.GrailsAnnotationConfiguration dataSource { configClass = GrailsAnnotationConfiguration.class Otherwise GORM won't see the domain classes. As for using real JPA APIs I haven't tested it. I will try it later and see what I find. Sam Hi Stephen,

When I use both together the application hangs. http://stephan.reposita.org/archives/2007/10/15/grails-hibernate-and-jpa-hanging-application/ Do you have any ideas? Did you successfully use JPA with Grails? Thanks -stephan Hi,
