[jboss-user] [JBoss Seam] - java.io.ByteArrayInputStream.<init>(ByteArrayInputStream.jav

[hager]

Hello,
I'm using seam 2.0.0.GA and JBoss server 4.2.0.GA
I'm trying an example with <pdf:image>, but i have java.io.ByteArrayInputStream.(ByteArrayInputStream.java:89) Exception.

Page.xhtml :

<p:image image="#{exportPDF.image}" spacingAfter="20" />


ExportPDF.java :

  | 	public BufferedImage getImage() {
  | 		BufferedImage image = null;
  | 		try {
  | 			String repertoireLogo = this.gestionConfiguration.getValue(typeConfigurationValeur);
  | 			this.pathImage = this.societeHome.getInstance().getLogoSociete();
  | 			if(this.pathImage != null)
  | 			{
  | 				System.out.println("pathImage "+pathImage);
  | 				StringTokenizer st = new StringTokenizer(this.pathImage,"/");
  | 				String nomFichier ="";
  | 				while(st.hasMoreElements())
  | 				{
  | 					nomFichier = st.nextToken();
  | 				}
  | 				byte[] pixels;
  | 				//Reading every byte from file
  | 				File logo = new File(repertoireLogo+File.separator+nomFichier);
  | 				if(logo.exists())
  | 				{
  | 					FileInputStream fis = new FileInputStream(logo);
  | 					
  | 					pixels = new byte[fis.available()];
  | 					fis.read(pixels);
  | 					System.out.println("Pixels "+pixels.length);
  | 					image = ImageIO.read ( new ByteArrayInputStream ( pixels ) );	
  | 				}
  | 			} 
  | 		}
  | 		catch (IOException e) {
  | 			System.out.println("Exception Image "+e.toString());
  | 		}
  | 		return image;
  | 	}



when I execute my method, I have this exception :
