    copied!<p>EDIT:</p> <p>Got the directory to live. Now there's another issue in sight:</p> <p>The files in the storage are stored with their DB id as a prefix to their file names. Of course I don't want the users to see those.</p> <p>Is there a way to combine the response.redirect and the header setting für filename and size?</p> <p>best,</p> <pre><code> A </code></pre> <p>Hi again,</p> <p>new approach:</p> <p>Is it possible to create a IIS like virtual directory within tomcat in order to avoid streaming and only make use of header redirect? I played around with contexts but could'nt get it going...</p> <p>any ideas?</p> <pre><code> thx </code></pre> <p>A</p> <p>Hi %,</p> <p>I'm facing a wired issue with the java heap space which is close to bringing me to the ropes.</p> <p>The short version is:</p> <p>I've written a ContentManagementSystem which needs to handle huge files (>600mb) too. Tomcat heap settings:</p> <p>-Xmx700m -Xms400m</p> <p>The issue is, that uploading huge files works eventhough it's slow. Downloading files results in a java heap space exception.</p> <p>Trying to download a 370mb file makes tomcat jump to 500mb heap (which should be ok) and end in an Java heap space exception.</p> <p>I don't get it, why does upload work and download not? Here's my download code:</p> <pre><code>byte[] byt = new byte[1024*1024*2]; response.setHeader("Content-Disposition", "attachment;filename=\"" + fileName + "\""); FileInputStream fis = null; OutputStream os = null; fis = new FileInputStream(new File(filePath)); os = response.getOutputStream(); BufferedInputStream buffRead = new BufferedInputStream(fis); while((read = buffRead.read(byt))&gt;0) { os.write(byt,0,read); os.flush(); } buffRead.close(); os.close(); </code></pre> <p>If I'm getting it right the buffered reader should take care of any memory issue, right?</p> <p>Any help would be highly appreciated since I ran out of ideas</p> <p>Best regards,</p> <p>W</p>
