PreparedStatement Error

Question

I'm getting this error when i try submitting values from my Jsp page into a database:
Method preparedStatement(java.lang.String)not found in interface java.sql.Connection.
The arrow that appears usually beneath the code in the error 500 message suggests that the problem is occuring in the insert statement, and im thinking it does'nt like the question mark in place of the value.
Is this because im importing the wrong class? my current class string is:
@page contentType="text/html; charset=iso-8859-1" language="java" import="java.lang.string.*" import="java.sql.*"
This is what the line within the program looks like:-
quote = Connquote.preparedStatement("INSERT INTO table1(A, B, C, D, E, F, G, H, I, J, K, L, M, N) values( ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ? )");

java.sql.SQLException:Parameter index out of range (1
number of parameters, w
If it says that it means you don't have any bind variables in your SQL.
Whah happens obj is null?Nothing to do with it. And you are writing code that is probably pointless as well. setObject() handles nulls.
