how to initialize and add data into list in the jsp view?

my model class is like this:

Manager.java

---

class Manager {

        int mgrId;
        String name;
        Set<Emp> employees;

// getter-setter methods       
}

---

Emp.java

Code:

---

class Emp {

        int empId;
        String name;
        String department;

// getter-setter methods

my jsp page is like this:

create_manager.jsp

Code:

---

<form:form modelAttribute="manager">

Manager Name: <form:input path="${manager.name}" maxlength="32" />

<table>
        <tr>
                <th>Emp Name</th>
                <th>Salary</th>
                <th>Department</th>
                <th>&nbsp;</th>
        </tr>

        <tr>
       
            <td><form:input path="${what shall i write here?}" /></input></td>
        <td><form:input path="${what shall i write here?}" /></input></td>
        <td><form:input path="${what shall i write here?}" /></input></td>
        <td><input type="button" value="Add New Employee" />

        </tr>

</table>

</form:form>

how to initialize Set<Emp> employees object in the above jsp view? what shall be the bindings. please help.

no responses? i guess, i failed to explain my problem properly.

let me try again:

i have a List object inside the model class. The List is null initially. how shall i write a jsp page that will let user to add multiple objects to List?

the problem is, if i wants to get the value of a String object of model class, i can write something like this:

<form:input path="${manager.name}" />

but, how can i do the same for List object of model class? please help.

I have the same problem... could anybody help? I have tried to make default initialization in the pojo class. but in jsp there is still empty list.

i have made this in my form controller:

HTML Code:

---

@RequestMapping(method = RequestMethod.GET)
        public String showForm(ModelMap model) {
                Client client = new Client();
                HashSet<Parent> parents = new HashSet<Parent>();
                parents.add(new Parent());
                parents.add(new Parent());               
                client.setParents(parents);               
               
                System.out.println(client.getParents().size());
                model.addAttribute("addClient", client);
               
                ArrayList<ClientGroup> groups = (ArrayList<ClientGroup>)groupServis.getListGroups();
               
                model.addAttribute("groups", groups);
               
                return "addClientForm";
        }

---

but in jsp there is still parents size = 0
<c:out value="${fn:length(client.parents)}"/>
