How can I keep GWT from trying to include every serializable class when I use ArrayList

Question

I have an RPC service in GWT that needs to return a List. The List can be filled with various types of objects, all of which are serializable and all of are referenced elsewher

Answer 1

You will have to help GWT by being very precise in what you return. A typical solution is to use a root class or marker interface and declare that the RPC method returns an ArrayList, then GWT can trim down the possible types.
