title: GWT using domain models /services from external module (jar)?
body: <p>Greetings,</p>
  
  <p>We have been using our reusable "user-management" module which was written using Spring/Hibernate(using Doman-Model Pattern).We have used that module in several project integrating with Wicket,JSP and ZK frameworks.
  Now I am going to develop an application using GWT.I am completely new to GWT and I noticed that the domain objects should go inside "xxx.xxxx.client" package.
  But I want to use our reusable module (jar) and the domain model is in completely different package.
  How can I use my domain-model object from this external library in GWT?
  How about service interfaces? Do I have to write proxies for them too?</p>
  
  <p>thanks in advance</p>
