Re: Overriding processCall to intercept RPC calls

Instead of this I would just extend RemoteServiceServlet and add a public static method that makes the session available to everyone (just like RequestFactoryServlet does), e.g.

public static HttpSession getThreadLocalSession() {

  return getThreadLocalRequest().getSession();

}

Then in your service method:

public boolean isUserLoggedIn() throws IllegalArgumentException {

  HttpSession session = YourExtendedRemoteServiceServlet.getThreadLocalSession();

  if(session.isNew()) {

    throw new IllegalArgumentException("Logged out");

  }

}

That way you actually see the session check at the correct place and not hidden in your RemoteServiceServlet implementation.
