GWT RPC on Vaadin

Hello,
I’m try implement GWT RPC on my Vaadin Project ( hybrid ), but until now don’t work propertly !
use maybe someone GWT RPC ? ( what points are different from raw gwt project ? )

  • e.g I see on gwt rcp example in xxx.gwt.xml modul rename keyword ! If i try use this whole project behavior strange…
  • in web.xml what url-pattern is to set ?

Thanks
Marian
