How to create a shared lib/utility class (client/server) ?

Hi,

I am trying to implement a small utility class / library that should be useable on client side and on server side but has different implementation on client and server.

For example I have a utility method that should make a http REST call. On client side I should use RequestBuilder but on server side I have to use java.net.* classes. How would I do that?

I tried the factory approach in combination with GWT.isScript() but this didn't work because the GWT compiler still sees java.net.* classes and wants to translate them:

public class SharedUtils {
  private static final SharedUtilsFactory FACTORY = GWT.isScript() ?
       new SharedUtilsFactoryJS() : new SharedUtilsFactoryVM();

  public static RequestUtils requestUtils() {
    return FACTORY.requestUtils();
  }

}

Shouldn't this somehow be possible?

Thanks for help,
