title: GWT with JPA
body: <p>I'm trying to build database application using GWT 1.5.3. I use JPA annotations with my objects.   It seems in hosted mode GWT's RPC works fine. But when I try to compile my app using GWT-compiler I get errors like: "The import javax.persistence cannot be resolved", "Entity cannot be resolved to a type". toplink-essentials.jar is already included in my project path. What settings else do I need to solve this problem? </p>
