You don't need to load POJO before update them.
If you populate the good key Hibernate manage the update alone.
But could you give us more details for mapping files or source files.

I know. I don't have my mapping files now, but I will try to explain for you.

I have a User.hbm.xml and Group.hbm.xml.
In User.java has a "Collection groups".

In my WebWork Action, I have the save() and getUser() methods.

Quote:

public class Action. implements Action
{
private User user = new User();
public void save(){
session.saveOrUpdate(user);
// Will this delete all groups from this User?
}
// get/set to User
}

WebWork will instanciete a new object User, then this object has a Collection groups=null. Then, Hibernate will delete all groups.

Because this, I'm loading a object with same primary key from database.

any idea?

Thank you
