I want to keep  multiple checkboxes in the JSP page . I want to save and retrieve their values .
Could you please help me to find a  easy and best  solution ? I'm explaining below where I need help.



Question :

Q1: What should be the checkbox names ?

Example:  

I have existing code ..
..................
..................
while (regioniterator.hasNext()){
  String region = (String)regioniterator.next(); // get the key

 // I want to create 15 checkboxes  for each region . How do I keep the checkbox name ?
 // Here is a proposed design . is this a good design  ?

   for(int j=0;j<15;j++){ % > <input type="checkbox"    name="<%=region><%=j>" value="" align="middle"> <% }%>

 }



 Q2:

 When the form  be submitted to the action class. How do I retrieve them in the action class ?
 I'm stuck here . Because all those many checkboxes are created dynamically .  I can not use request.getParameterName() now in the action class to retrieve from the request .

 What trick to apply here ?


 Q3:

 How do I save so many checkbox values in the DB ? I need to save and retrieve their values  in the JSP also.

 What table and how many column to make here to hold their values  ?
 
 How the table design will look like ?
