Float truncated when inserted into table

Question

Hi,
I'm trying to insert float values into a table with a column of type NUMBER(4,2) and the values are getting truncated to integer values. My environment is :
Database: Oracle8i Enterprise Edition Release 8.1.7.0.0 - Production
jdbc lib: 9.0.1.4
I tried it with the jdbc lib version 9.0.1 and it works, but I didn't figure a way to use it, since I'm using it in a 9iAS environment and there's no driver classes12dms.jar for this version. If I try to use the classes12.zip version I get an exception when trying to access the database complaining about some classes missing (These classes missing are in the classes12dms.jar)
Here's a simple test case:
import java.sql.*;
public class TesteFloat {
public TesteFloat() {
public static void main(String[] args) {
Connection con = null;
PreparedStatement stmt = null;
try {
Class.forName("oracle.jdbc.driver.OracleDriver");
con = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:hal9000","kitbordo","kitbordo");
stmt = con.prepareStatement("insert into teste (teste) values (?)");
for (int i = 0; i < 10; i++) {
stmt.setFloat(1,2.32f * i );
//stmt.addBatch();
stmt.executeUpdate();
//stmt.executeBatch();
con.commit();
} catch (Exception e) {
e.printStackTrace();
} finally {
if (con != null) {
try {
con.close();
} catch (SQLException e) {
CREATE TABLE TESTE
TESTE NUMBER(4,2)
)
