accessing session variables in java Bean(In business logic Layer)

Hi
I use plain java beans for model/business layer.
I have a question regarding accessing session variables in java Beans(In model
Layer). I can pass session variables from action class but is there any other
way I can access session variables directly by extending any class. 
Because I need "session.userID" every time I make an insert/update in the
database and I feel it is redundant passing session variables every time along
with the form data(DTO) to java bean.

My example java bean code is as follows

public class DoInsertBean
{   
	private DataSource dataSource = null;	
	public DoInsertBean(DataSource dataSource)
	{
		this.dataSource = dataSource;
	}	      
    
    public int insert(UserDTO user){
    //Insertion into database
    //need session variables here??
       }
}

Thanks,
Mallik

struts-config identifies a forward to an identifier
The identifier is associated with the implementted action Class
The action class contain execute methods which reference 
HTTPServletRequest/HTTPServletResponse parameters
which can getSesssion and setSession for whatever parameter you desire
Is there something specific you want?

All of our application state (including the user) is kept in a
separate "session" object in the business layer.  (We use a stateful
session EJB, but you could easily write your own POJO for this.)  The
web session, then, only has a reference to this session object (and a
few other view-specific variables, for tracing page history and the
like).
