so you are missing a class .... add all dependent jars to the classpath.

I have done,but it doesn't work...

Thank you for your help!!
what's the jars i need?

Are you using a foreign identifier on a one-to-one relationship and have failed to specify a property? Your mappings may help

all jars from hibernate distribution

I'm a fresh ,this is my first project...

Users.hbm.xml
<?xml version="1.0"?>

</class>
</hibernate-mapping>

Action

public ActionForward execute(ActionMapping mapping,ActionForm form,HttpServletRequest request,HttpServletResponse response)
{
LoginForm loginForm = (LoginForm) form;
ActionMessages errors = new ActionMessages();
SessionFactory sessionFactory;
try
{
sessionFactory = new Configuration().configure().buildSessionFactory();
}
catch (Exception ex)
{
errors.add("msg",new ActionMessage("failure"));
saveMessages(request,errors);
return mapping.getInputForward();
}
Session session = (Session)(new ThreadLocal().get());
if(session != null)
{
try
{
session = sessionFactory.openSession();

Users user = new Users();
user.setId(loginForm.getId());
user.setPwd(loginForm.getPwd());
user.setUsername(loginForm.getUsername());
session.save(user);
errors.add("msg",new ActionMessage("success"));
saveMessages(request,errors);
return mapping.getInputForward();
}
catch(Exception e){}
}
errors.add("msg",new ActionMessage("failure"));
saveMessages(request,errors);
return mapping.getInputForward();
}

...and you have all the lib jars (in the lib folder) + the hibernate2.jar on your classpath?

Why you know this????

?? Not sure what you mean.

You need to work out which class is not found. Once you have this information let us know.

Thank you ,I'm finding it now...

you have to read documentation

A little...

It's working...
:-)
