//how to enter the data in JTextArea by calling procedure as i
//have done above for the JTable and i know that i didnt create the
//object for detail button of ActionListener type*/*

                   i++;
                }
            }

                JOptionPane.showMessageDialog(frame, e+"");

            }

        }

    }

}

Edit :source code of stored procedure

create proc detailsStaffPortal 
@complaintNo int 
as 
begin 
select remarks,description from complaintTable where complaintNo=@complaintNo 
end

String str1=rs.getString(1); String str2=rs.getString(2);

                remarksArea.setText(str1);
                descriptionArea.setText(str2);
                descriptionScroll.add(descriptionArea);
                remarksScroll.add(remarksArea);

by using string we can store the data firsrt and then use setText
