upload the csv file those records should be inserted corresponding fields of the table in the dabatase

This should make it easier:

Some dbs can load CSV automatically btw

through java i have to do this

I'd use the above with a PreparedStatement in batch mode

just tell me a psecudo code how to read csv file using CSVParser

You don't need pseudo. There's actual code on the main page:

http://ostermiller.org/utils/CSV.html

ur talking abt this;but here how will u pass cvs file??

String[][] values = CSVParser.parse(new StringReader(""));

// Display the parsed data
        for (int i=0; i<values.length; i++){
            for (int j=0; j<values[i].length; j++){
                System.out.println(values[i][j]);
            }
            System.out.println("-----");
        }

>>how will u pass cvs file??

You don't pass the CVS file. You insert individual values in that array into the DB

String[][] values = CSVParser.parse(new FileReader(new File("c:/chaitu/emp.csv")));

// Display the parsed data
        for (int i=0; i<values.length; i++){
            for (int j=0; j<values[i].length; j++){
                System.out.println(values[i][j]);
            }
            System.out.println("-----");
        }

in the emp.csv file i have id and name values will be stored.......

(If 'id' is not a String, obviously make the appropriate adjustments)

so what i am doing is correct

String[][] values = CSVParser.parse(new FileReader(new File("c:/chaitu/emp.csv")));

Yes
