The new SessionData object doesn't do anything.  It only stores data and
provides
method for storing and retrieving that data.

public class SessionData
{
    int longfield;
    public SessionData() {}

    public void setLongfield(int longfield){ this.longfield=longfield; }
    public int getLongfield(){ return longfield; }
    // so on for other data
}

Then in servlet after getting value for longfield:

int longfieldValue = // GET IT FROM DATABASE
SessionData sData = new SessionData();
sData.setLongfield(longfieldValue);
session.putValue("SessionData",sData);

then in JSP:
<jsp:useBean id="dataBean" class="SessionData" scope="session"/>
You have retrieved the following value: <%= dataBean.getLongfield() %>
