File Upload type image

Bonjour,
j'ai réussi à parcourir le répertoire et uploader une image dans C:/temp et elle est enregistrée mais mon problème est l'affichage de cette image dans ma page xhtml,voici mon bean:
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;

import javax.faces.application.FacesMessage;
import javax.faces.bean.ManagedBean;
import javax.faces.context.FacesContext;

import org.primefaces.event.FileUploadEvent;


@ManagedBean
public class FileUploadController {

private String caminho;
public void handleFileUpload(FileUploadEvent event) throws FileNotFoundException, IOException {
String caminho;
//logger.info("Uploaded: {}", event.getFile().getFileName());

FacesMessage msg = new FacesMessage("Succesful", event.getFile().getFileName() + " is uploaded.");
FacesContext.getCurrentInstance().addMessage("teste", msg);

byte[] conteudo = event.getFile().getContents();
caminho = "C:\\tmp\\" + event.getFile().getFileName();
FileOutputStream fos = new FileOutputStream(caminho);
fos.write(conteudo);
fos.close();

}
public String getCaminho() {
return caminho;
}
public void setCaminho(String caminho) {
this.caminho = caminho;
}
{System.out.println("l'image est: "+caminho);}
}

Il suffit d'ajouter

Code:

---

1 2 3 4

InputStream ist = new ByteArrayInputStream(conteudo); image = new DefaultStreamedContent(ist, "image/jpg"); // sans oublier de déclarer la variable image --> private StreamedContent image;

---

Code:

---

<p:graphicimage value="#{fileUploadController.image}" id="imgage" width="140">
