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
