SmartGWT integration with Spring

[dafra]

Hello,
I would like to use SmartGWT in GeoMajas project which gives widgets based on SmartGWT. GeoMajas is configured by Spring framework.
Moreover I would like to integrate my app with Spring but I don't know if I can use libraries for integrate GWT with Spring in SmartGWT.
I would like to use libraries as :
