Am i able to set a class object to session?

Question

Hi,
i want to store some session data in a web application. I understand session can be set by this way:
session.setAttribute('student', name);
session.setAttribute('teacher', name2);
However the method above stores one a value in a session. I want to store many data in a session. I have code in this way for learning purposes. This is what i'm doing picking from bits and pieces from the internet. Please advise if whether i'm on the correct track.
I have a student class
public class Student {
    String name;
public String getName() {
          return name;     
public String setName(String name) {
          this.name = name     
I have a teacher class
public class Teacher{
      String name;
      public String getName() {
          return name;     
      public String setName(String name) {
          this.name = name     
I create a SchoolSessionBean class to store this object into a session
public class SchoolSessionBean {
       private Student student;
          private Teacher teacher;
       public SchoolSessionBean {
       public Student getStudent() {
         return student;
       public void setStudent(Student student) {
         student = student;
        public Teacher getTeacher() {
         return teacher;
       public void setTeacher(Teacher student) {
         teacher = teacher;
}Ok. Now i want this SchoolSessionBean class to store in a session. This SchoolSessionBean class also stores the data for the student and teacher.
Inside this class, this is what i coded to store the SchoolSessionBean into a session
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
public class createSession{
     Student student = new Student();
     Teacher teacher = new Teacher();
     student.setName("John");
     teacher.setName("Dave");
     HttpSession session = request.getSession();
     SchoolSessionBean schoolSessionBean = (SchoolSessionBean)session.getAttribute("schoolSessionBean");
     schoolSessionBean.setTeacher(student);
     schoolSessionBean.setUsagerDetails(teacher);
}I have not create the jsp but if on the jsp, can i get the session of the schoolSessionBean anywhere, on any page of the jsp and get the values from the student and teacher class using the codes below?
Can i use the codes below to retrieve the values of the names on any page of the jsp?
These codes are implemented on JSPS.
SchoolSessionBean schoolSessionBean = (SchoolSessionBean)session.getAttribute("schoolSessionBean");
String name1 = schoolSessionBean.getStudent().getName();
String name1 = schoolSessionBean.getTeacher().getName();Edited by: leeChaolan on Mar 24, 2009 9:11 AM

Oh i see. So if i want to set the class to a session, can i do it this way as shown below? I plan to try it tonight to see if it works. But just at the mean time, i like to seek some advice on my codes.
SchoolSessionBean schoolSessionBean = (SchoolSessionBean)session.getAttribute("schoolSessionBean");
     schoolSessionBean.setTeacher(student);
     schoolSessionBean.setUsagerDetails(teacher);Thanks
