Form with dynamic id & name fields

I have a form that looks like this : cat1 [int field] cat2 [int field] cat3 [int field]

The fact is that my categories are different each time. How do i Handle this in my handler ?

Dont know how i should set my getter/setter

Heres my jsp : 

    <jsp:useBean id="formHandler" scope="page" class="com.pipo.EditStatusMappingHandler"><%--
--%><jsp:setProperty name="formHandler" property="*" /><%--
--%></jsp:useBean>

<form action="jsp/form/mapStatus.jsp" method="POST" name='categoryForm'>     
        <ul>
        <foreach collection="<%= categorySet %>" type="Category" name="itCategory" >
           <li>
            <label for="<%= itCategory.getId() %>"><%= itCategory.getName(userLang) %></label>
            <input type="text" name="<%= itCategory.getId() %>" id="<%= itCategory.getId() %>"/>    
           </li>
        </foreach>
        </ul>
          <div class="modal-buttons buttons">
            <input style="text-align:right;" class='formButton mainButton'  type="submit"/>
    </form>

I dont know what to put in my handler to get the input name = <%= itCategory.getId() %>

If you use a Map<String, Data> the getters and setters are defined for you.

Map<String, Data> map = new LinkedHashMap<String, Data>();
// set values.
map.put("field1", data1);
map.put("field2", data2);
// get values.
Data dataA = map.get("field1");
Data dataB = map.get("field2");

Most of the Java web frameworks support mapped properties (i.e. getCategoryValue(String categoryName) / setCategoryValue(String categoryName, Integer value)) or direct read-write access to a map inside the form bean/action bean.

Without knowing the framework you're using and what you mean by "handler", it's difficult to give a more precise answer."

Best way is to use reflection on the form object to get to know the category fields and invoke the corresponding operation.
