Session value to JavaBean

Question

i have a value and set it to session. I can get it by session.getAttribute(" xxx") at another jsp page, Can I pass the value into a java class to perform some task ?

Answer 1

Sorry about that, i do not know about the HttpSession
I have this in a.jsp page
String sRand="";
for (int i=0;i<4;i++){
String rand=String.valueOf(random.nextInt(10));
sRand+=rand;
g.setColor(new Color(20+random.nextInt(110),20+random.nextInt(110),20+random.nextInt(110)));//???????????????????????????????
g.drawString(rand,13*i+6,16);
session.setAttribute("rand",sRand);
in JSF a inputText for user enter value
in Validator file i write this
public void validateCode(FacesContext context, UIComponent toValidate,Object value) {
          String code = (String) value;
// is it declare HttpSession code here? But how i specify the session is from the a.jsp page
          if (!rand.equals(code)) {
               throw new ValidatorException(new FacesMessage("Invalid"));
          }
