I don't know, how your application is structured, but why don't you use Spring 3 with REST and JSON?
Spring 3 comes with a cupel of nice features to create RESTful APIs on top of Spring Controllers. This fits much better into the Spring world, than GWT RPC could ever do. On the other hand, GWT + JavaScript Overlays makes the usage of RESTful API with JSON very smart to GWT apps. We'd the same idea for the Grails GWT plugin, since Grails comes with REST build in and GWT-RPC never felt native. For me it would definitively be the preferred way in a Spring world.
