I had a similar problem when I started working with web flows.

when? Check This Out Code: public class AddCourseWrapper implements Serializable { ... } P.S. Do you know if I'll be safe using services as singletons & depending on Spring to manage the transaction? The object it's complaining about is probably not your service but rather one of your domain objects.

The Hibernate session holds references to all the attached domain objects. The service is > basically persisting the result of the webflow actions. From the reading I've done, it seems like the service needs to change to the flow scope & implement serializable, and any objects the service touches must also be serializable.
