GWT, Spring and Hibernate

Over the past few days I've been exploring the use of GWT (Google Web Toolkit), Spring and Hibernate to create web applications. I've read about several different methods of using these technologies together each with there own strengths and weaknesses. I am new to GWT, Spring and Hibernate and would like to figure out best practices for using these technologies together. I decided to start a reference web application on Google Code as a way to explore some patterns and practices for building websites with GWT, Spring and Hibernate. My hope is that other developers will join me in this exploration.
