Hibernate Reverse Engineering + GWT RequestFactory

[Big38]

I'm a total noob in RequestFactory and Hibernate, so bare with me a
little :) Any help or pointer is much appreciated.

I'd like to know if it's possible to integrate the Hibernate Reverse
Engineer generated files with GWT's RequestFactory.

If it is, does anyone have any example project that they can show me?
I reverse engineered a db table and included in the server package of
the project.
I can reverse engineer a db table and instantiate the DAO object to
get data and output in a normal java project.
However, when I tried to instantiate the DAO object on the server in a
gwt project, I get the following exception...

[WARN] Server class 'org.hibernate.criterion.Criterion' could not be
found in the web app, but was found on the system classpath

sl4jThe problem is related  to classpath. You don't have sl4j in your classpath.
