import java.sql.*;

Connection con = null;

try {
   Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");

   con = DriverManager.getConnection("jdbc:odbc:<DSN>");

   Statement stmt = con.createStatement();
   stmt.executeUpdate("Insert into <your table> (field1, field2, field3) values (<param1>, <param2>, <param3>)");
   stmt.close();
} catch (Exception e) {
   System.out.println(e.getMessage());  
} finally {
   if (con != null) { con.close(); }
}

to get parameters from form:

String param1 = request.getParameter("param1");
String param2 = request.getParameter("param2");
String param3 = request.getParameter("param3");
