    java.io.ByteArrayInputStream.<init>(ByteArrayInputStream.jav

    hager hager Newbie

      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 :
      java.lang.NullPointerException
