Damn .. you are the man hat solved my problem.
I started with the StockWatcher application, and then added my Hibernate
POJO's and DAO;s.
However, I had the DAO's under the client directory, when I managed to move
those DAO's to the /server section, then it worked.
I am now able to get my data from the database, and it did show up on my UI.
So ... there are a number of issues I am working through ... but I've gotten
past this log jam.
Thanks very much for the help!
