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

[Mallik]

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
