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() %>
