Ji Janko, yes you get this Error Message, if the client doesn´t know the source-code of the object. As Brett said, move it to the shared package.
Note: You can´t use persisted classes on the client. But in the StockWatcher example there nothing is persisted, so moving your class to the shared package will solve your problem.
