Why do I get java.io.IOException: Stream Closed? (java 7)

Question

I try save uploaded file as described here using Files.copy(inputStream, path to file,replace existing)

Here is method that throw exception

    public void handleAudioUpload(FileUploadEvent event) {
    UploadedFile audio = event.getFile();
    try (InputStream audioInStream = audio.getInputstream();) {
        MP3Util util = new MP3Util(audioInStream);
        Map<String, String> tags = util.getAudioTags();
        System.err.println(tags);
        System.err.println(webAppPath);

        Date currentDate = new Date();
        @SuppressWarnings("deprecation")
        String[] arr = currentDate.toGMTString().split(" ");
        String target = arr[2] + "/" + arr[1] + "/" + arr[0];

        Path mainPath = Paths.get(webAppPath + userFiles + audioFiles + "/"
                + target + "/" + audio.getFileName());
        mainPath = Files.createDirectories(mainPath);
!!!Line 43!!!       Files.copy(audioInStream, mainPath, StandardCopyOption.REPLACE_EXISTING);
    } catch (IOException e) {
        e.printStackTrace();
    }
}

These create all folder and file but file is empty/broken

And my exception

I think that problem is like here but I don't know how fix it.

how did you implement the `UploadFile.getInputStream()`? could you upload the relevant code? — Blip, May 09 '15 at 13:33

You get that exception because the stream is closed.

The stream is closed because some code closed it before your call to Files.copy().

Given that it isn't closed in the code you posted, but that you passed the stream to MP3Util's constructor, we can safely conclude that this constructor, or the method getAudioTags() that you call right after, has closed the stream.

Unless of course audio.getInputstream()returns a stream that is already closed.

If Mp3Util is the culprit, then the potential fixes are:

stop using it, since it seems it's only there to print debugging statements to System.err
reopen the stream once you have used in Mp3Util.

you have repeated the OP problem in your own words. His question is **"but I don't know how fix it."** – Blip May 09 '15 at 13:36
Thanks, now it works. I invoke `close` in `getAudioTags` method. – Bohdan Zv May 09 '15 at 13:42
