I am trying to create a generic method for object updates using scala / java but I can't get the class for a type parameter.

Here is my code:

object WorkUnitController extends Controller {     
 def updateObject[T](toUpdate: T, body: JsonObject){
  val source = gson.fromJson(body, classOf[T]);
  ...
 }
}

The error i get is

class type required but T found

I know in java you can't do it but is this possible in scala at all?

Thanks!
