Groovy and Grails are emerging, dynamic technologies that are taking the J2EE development world by storm. We are on the leading of edge of adoption with these technologies. We have brought Groovy integration into J2EE insurance software applications. We are actively developing a Grails 1.1 site with some very cool web 2.0 AJAX features. See our recent blog which goes in depth into one of the more interesting features of this project.
Spade has an established client list of Groovy, traditional J2EE, and Ruby on Rails applications. We are merging this experience into efforts to grow our Grails practice.
