Use smartGwt with playframework

Please Ho开发者_如何学编程w can I integrate smartGwt 2.3 with play?, I'm using GWT2 [gwt2] module 1.8, but I don't know how to add smartgwt components

Well it runs with this configuration

require:
    - play
    - play -> gwt2 1.8

    - com.google.gwt -> gwt-user 2.3.0
    - com.google.gwt -> gwt-dev 2.3.0    
    - com.smartgwt -> smartgwt 2.5


repositories:
    - smartgwt:
        type: iBiblio
        root: "http://www.smartclient.com/maven2/"
        contains:
            - com.smartgwt -> *

I would recommend the way from Raphael Bauer which is described at the google-group. There Play is a restful-server which delivers JSON-Messages. Then you use GWT with RestyGWT. No need to use a special module. So you can use GWT-Extension as you usual do.
