Spring One : GWT/Spring

Interesting presentation with mostly features of GWT plus a few integration points for Spring Business layer.

Sadly, no insight on future support for Java 5 Annotations, and no first idea of the upcoming version 1.4 which deals with the IsSerializable vs. Serializable issue amongst other things (modular RPC services for example removing the need for GWTHandler in order to integrate wutg spring).

Conclusion: until further notice, DTOs should be used with the addition of a specific Service Facade Layer to the business layer and a DTOConverter (Special mention for Spring's BeanUtils for the copy of objects' states).

My own conclusion: wait for version 1.5 of GWT for a more completely useable GWT, and keep experimenting with it.
