JSP

I am into a project wherein i am required to make a form in which a user enters the details and the same gets updated in database. the table structure is as follows:

Month   MS_TARGET   HSD_TARGET   ALPG_TARGET   LUBES_TARGET   TYRES_TARGET
APRIL					
MAY					
JUNE					
JULY					
AUGUST					
SEPTEMBER					
OCTOBER					
NOVEMBER					
DECEMBER					
JANUARY					
FEBRUARY					
MARCH	

I have months on Y axis and Certain Target fields on X axis.I have total of 60 fields.
I want to iterate through all the fields and insert the same in the database.I thought of using hashmap. according to my knowledge i created hashmap column wise.
eg:

HashMap <string,> MS_Target= new HashMap <string,>();

	MS_Target.put("April",new Integer(1));
	MS_Target.put("May",new Integer(2));
	MS_Target.put("June",new Integer(3));
	MS_Target.put("July",new Integer(4));
	MS_Target.put("August",new Integer(5));
	MS_Target.put("September",new Integer(6));
	MS_Target.put("October",new Integer(7));
	MS_Target.put("November",new Integer(8));
	MS_Target.put("December",new Integer(9));
	MS_Target.put("January",new Integer(10));
	MS_Target.put("February",new Integer(11));
	MS_Target.put("March",new Integer(12));

like wise for all columns.total i have 5 hashmap. My concern is how do i insert the hashmap data in my database....Any help would be highly appreciated as i am a newbie to jsp .....
