Oracle 9i Update problem

Question

Hi, i�ve the following problem using an oracle 9i database
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.OutputStream;
import java.io.IOException;
import java.sql.*;
public class prueba
public static void main (String[] args)
File far = new File("C:\\EyeCandyLog.txt");
try{
FileInputStream fis = new FileInputStream(far);
java.lang.Class.forName("oracle.jdbc.driver.OracleDriver");
Connection con = DriverManager.getConnection("jdbc:oracle:thin:@10.239.208.126:1521:TWEDES","twecms","ABDGC");
con.setReadOnly(false);
Statement stmnt = con.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_UPDATABLE);
if(stmnt.execute("SELECT * FROM PRUEBA WHERE id= 1"))
ResultSet rset = stmnt.getResultSet();
set.first();
rset.updateBinaryStream("MIBLOB",fis,Integer.parseInt(""+far.length()));
rset.updateRow();
rset.close();
stmnt.close();
con.close();
fis.close();
catch(Exception e)
System.out.println("Error\n"+e.toString());
I get the next:
Error
java.sql.SQLException: Operaci�n no v�lida para el juego de resultados de s�lo lectura: updateBinaryStream
it�s like "Not valid operation for Read only ResultSet: updateBinaryStream"
I really need your help, thanks

I�ve yet corected these problems, but i get another one: without exceptions, there no change in my Blob, here�s the function used:
import java.io.File;
import java.io.FileOutputStream;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.InputStream;
import java.io.OutputStream;
import java.io.IOException;
import java.sql.*;
public class prueba
private static boolean set = false;
     public static void main (String[] args)
if (set)
               File far = new File("C:\\EyeCandyLog.txt");
try{
               FileInputStream fis = new FileInputStream(far);
java.lang.Class.forName("oracle.jdbc.driver.OracleDriver");
Connection con = DriverManager.getConnection("jdbc:oracle:thin:@10.239.208.126:1521:TWEDES","twecms","ABDGC");
con.setAutoCommit(false);
con.setReadOnly(false);
Statement stmnt = con.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_UPDATABLE);
if(stmnt.execute("SELECT ID,NOMBRE,MIBLOB FROM PRUEBA WHERE ID=1 FOR UPDATE"))
ResultSet rset = stmnt.getResultSet();
rset.first();
rset.updateString(2,"EyeCandyLog.txt");
rset.updateBinaryStream(3,fis,Integer.parseInt(""+far.length()));
rset.updateRow();
con.commit();
con.close();
fis.close();
catch(Exception e)
System.out.println("Error\n" + e.toString());
else

Blob bl = rset.getBlob(3);
System.out.println("0\n"+bl);
byte[] buffer = new byte[Integer.parseInt(""+bl.length())];

System.out.println(new String(buffer));
