First, Hibernate Mailing List might be a better list to answer your questions.
However, i'll try to answer as am also an Hibernate user.

You mean you are persisting the Struts forms in database?
This is dangerous i think. I'll recommend using the delegate design
pattern to prevent user access to some setters of the bean
(eg. Hibernate requires you to have a setOwner on a bean to
populate it from database but you don't want somebody to be
allowed to change the owner by doing someAction.do?owner=SomeFakeOwner)
So better have form do this:
getXXX(){
return theBean.getXXX();
}
and persist theBean :)
This way you have better control on form setters

As Hibernate documentation says, put it along the POJO. If Hibernate didn't
find it, it's perhaps
because of your compilation process. Some ide/automated tools like maven only
compile classes
in src/ directory to target/ directory, they do not copy ressources. Try to
create a separate ressources
directory which is copied in target directory as part of compilation process.
For info, here we put our .hbm files in
webapp/WEB-INF/classes/com/company/somePath
because in compilation process, webapp/* is copied in final war :)
With all this, we have our own session factory which is a singleton having this
in constructor:
Configuration configuration = new Configuration();
// ensure that the *.hbm.xml is located in bin/be/rmi/intranet/db
// (where the class is)
for (int i = 0; i < persistedClasses.length; i++) {
configuration.addClass(persistedClasses[i]);
}
sessionFactory = configuration.configure().buildSessionFactory();
with
private static Class[] persistedClasses = new Class[] { V4_news.class,
Scpub.class, User.class, Function.class, FunctionBackup.class,
Vacancy.class, TimeKeeper.class, Project.class };
