This question keeps coming up - maybe it should go on the FAQ for GWT. With like giant flashing arrows pointing to what you have to keep in mind when developing GWT.
GWT is a client-side library (with some syntactic sugar for communicating with a server backend more easily). Although you write Java, it's javascript. That should explain to you why GWT won't compile your code - because those classes aren't on the classpath & they're not modules (and you really can't include them because it's highly likely they use stuff Javascript doesn't support). Here's my recommendation. Create a POJO wrapper you use on the server that implements those methods. When you communicate between the client & server, you pass the raw POJO, but the server always wraps the POJO in a richer class that has the more advanced functionality you need.
