Hi
I developed a program to send userid to excel sheet using jdbc...
While i opened excel sheet and try to send data through jdbc it works great ...
But the problem is while i closed the excel sheet and try to send data to excel sheet, it spells success.
But the data i entered is not in that excel sheet ...

          Connection con = DriverManager.getConnection("jdbc:odbc:Excel Files","","");
          PreparedStatement stat2 = con.prepareStatement("insert into
[Book1$](USERID,FIRST_NAME,LAST_NAME) values (?,?,?)");
          stat2.setString(1,textuserid.getText());
