Java ovviamente non ha nulla a che fare con oggetti OLE (roba Microsoft ....). In Java le immagini sono rappresentate da:
- java.awt.Image (e sottoclassi, tra cui BufferedImage che si può caricare/salvare con la API ImageIO).
- javax.swing.Icon e la implementazione predefinita ImageIcon (che incapsula un Image).

Se hai uno di questi ok. Altrimenti devi (ri)valutare la tua gestione delle immagini.

ho questo:
import java.sql.*;
import javax.swing.*;
import java.io.File;
import java.io.FileInputStream;
import javax.swing.ImageIcon;
import javax.swing.JFileChooser;
import net.proteanit.sql.DbUtils;
cosa posso fare(a parte darmi all'ippica XD), ciao grazie

import java.io.File;
import java.io.FileInputStream;
import javax.swing.ImageIcon;
import javax.swing.JFileChooser;
import net.proteanit.sql.DbUtils;

E allora? Non so cosa sia quel net.proteanit.sql.DbUtils. Immagino abbia a che fare con l'accesso a DB ma non posso sapere come e non saprei altro.
Se hai fatto una query, avrai qualcosa nella colonna del result-set per la immagine, giusto? Cosa?

Ehm ... dovresti spiegare tu meglio cosa stai usando. Parli di "tabella del database access". Bene, che codice stai usando per leggere materialmente i dati di quella tabella? Puoi mostrare il codice? O non l'hai ancora scritto?
