Yes, absolutely 100% I do have Hibernate working with Annotations! The Hibernate DAO's and POJO's have all been Unit Tested and work perfectly 100%. And we are using Spring with the DAO's and POJO's defined in the applicationContext.xml file. There are NO hibernate.cfg.xml and Object.hm.xml files defined, and we don't seem to need them since all that is defined within the applicationContext.xml file.
Yes, I have learned that I can't call Spring classes from within GWT. I agree with you, I need to create some DTO classes that handle the wire transfer between the UI and the database. I gather from reading that the DTO custom classes have to implement isSerializable and collections are ArrayList, String array, Vector, HashMap, and HashSet. So, I'm looking now for examples on when exactly the Service calls the backend database ... The GWT-RPC Service at some point either has to call the DAO's to create, retrieve/fetch, update, delete data. Where and how that happens I am looking for. I looked at Gilead and the samples, and they use Hibernate.cfg.xml and the Object.hbm.xml ... which I don't have in this application. So, if I found an example of Gilead with Spring, that would help. Thanks for the help, I do appreciate it! :-) Tom On Sep 9, 1:38 pm, Robnauticus- <robnauti...@gmail.com> wrote: > Hello Thomas, > > Do you have Hibernate working with annotations?
