HibernateDaoSupport and Transaction

[gokmen kisakol]

First of all I must say I am new in Spring. I try to a web application with spring+hibernate.
I have some classes

1.
@ManagedBean
@RequestScoped
public class UserBean {} calling service
2.
public class UserBO implements IUserBO{} calling UserDAO and will apply transaction in this class
3.
public class UserDAO extends HibernateDaoSupport implements IUserDAO {}


In this configuration, I want to use transaction in UserBO that is defined in applicationContext.xml., but I didnt do it.

Can you give me a sample how I can configure thr applicationContext.xml.

This is my applicationContext.xml but not working transaction on UserBO methods.

Function is;

	public List<User> getDatalist() {
		if(FacesContext.getCurrentInstance().getRenderResponse()){
			ServiceLocator locator = new ServiceLocator();
			service = (IUserBO)locator.lookupService("proxyService");
			datalist = service.findAll();
		}
		return datalist;
	}
