How to store multiple objects in a session one by one per request?

Question

I am working for application where i have to send one object per request.And i have to store the whole data in a session variable.How can i do that? I am sending the data into controller and creating the object and then trying to store in a session ,but it is not working and this is my code

MemberDependentBO memberdepinfo = new MemberDependentBO();

        memberdepinfo.setFirstName(getMemberFirstName().getValue().toString());
        memberdepinfo.setLastName(getMemberLastName().getValue().toString());
        memberdepinfo.setMiddleName(getMemberMiddleName().getValue().toString());
        memberdepinfo.setPassport(getMemberPassportNumber().getValue().toString());

    List<MemberDependentBO> listOfMemberAndDep = new ArrayList<MemberDependentBO>();

        listOfMemberAndDep.add(memberdepinfo);

        httpSession.setAttribute("insuredInfo", listOfMemberAndDep);

        System.out.println("List Size :"+listOfMemberAndDep.size());

Every time when i click the button,the object is coming from the controller .but each time i am getting the size of the list is 1.Any Help will be appreciated

First try to pull listOfMemberAndDep out of the current session. If it doesn't exist, create it, add memberdepinfo and save in session. If it does exist, just add memberdepinfo and re-save in session. Something like this....

List<MemberDependentBO> listOfMemberAndDep = (List<MemberDependentBO>)httpSession.getAttribute("insuredInfo");

if(listOfMemberAndDep == null){
    listOfMemberAndDep = new ArrayList<MemberDependentBO>();
}

MemberDependentBO memberdepinfo = new MemberDependentBO();
memberdepinfo.setFirstName(getMemberFirstName().getValue().toString());
memberdepinfo.setLastName(getMemberLastName().getValue().toString());
memberdepinfo.setMiddleName(getMemberMiddleName().getValue().toString());
memberdepinfo.setPassport(getMemberPassportNumber().getValue().toString();

listOfMemberAndDep.add(memberdepinfo);
httpSession.setAttribute("insuredInfo", listOfMemberAndDep);
System.out.println("List Size :"+listOfMemberAndDep.size());
