Im trying to design a financial year table...wherein the user enters the data in the table and the same is updated in backend.i have successfully desinged the page but i have certain doubts in jsp code.the table is as follows:

MS_target   HSD_Target       ALPG_Target    Lubes_target
april               
May             
June                
July                
August              
September               
october             
november                
december                
january             
february                
march               

The HTML code is fine but im confused on to the JSP part as using an array is not possible. I have tried using the hastable by creating a hashmap for all the months. is it fine to use hashmap...or else kindly suggest me to some alternative.I have given names for all fields separately.also suugest me a code on how to iterate through all the fields.

HashMap april= new HashMap();
april.put("aprMS",new Integer(1)); 
april.put("aprHSD",new Integer(2)); 
april.put("aprALPG",new Integer(3)); 
april.put("aprLubes",new Integer(4)); 

Like wise i ahve created hashmap for all months.but i have doubts on how to read the hashmap data and insert the same in database. Kindly help.
