Image after upload not available (Apache Tomcat)

Question

Hello!
I'm using file upload from Apache MyFaces to upload images. The upload works perfectly. But when I try to show the image on a webpage right after uploading, the file is not found. I know that the link is correct and the file exists. Somehow my Tomcat server doesn't realize that there is a new file to index. When I restart the server, everything works and the image is shown.
Can you help me? I think I have to tell the server that there is a new file or something like this...

Yes, I did close the stream.
This is my code:
File f = new File("/home/wolfgang/NetBeansProjects/Webshop/web/img/products/" + fileName);
inputStream = productNewImage.getInputStream();
OutputStream out = new FileOutputStream(f);
byte[] buf = new byte[1024];
int len;
while ((len = inputStream.read(buf)) > 0) {
      out.write(buf, 0, len);
out.close();
inputStream.close();
