java - Problems passing class objects through GWT RPC

Question

I've run through the Google Web Toolkit StockWatcher Tutorial using Eclipse and the Google Plugin, and I'm attempting to make some basic changes to it so I can better understand the RPC framework.

I've modified the "getStocks" method on the StockServiceImpl server-side class so that it returns an array of Stock objects instead of String objects. The application compiles perfectly, but the Google Web Toolkit is returning the following error:

"No source code is available for type com.google.gwt.sample.stockwatcher.server.Stock; did you forget to inherit a required module?"

It seems that the client-side classes can't find an implementation of the Stock object, even though the class has been imported. For reference, here is a screenshot of my package hierarchy:

I suspect that I'm missing something in web.xml, but I have no idea what it is. Can anyone point me in the right direction?

EDIT: Forgot to mention that the Stock class is persistable, so it needs to stay on the server-side.
