Subject [jira] [Updated] (FILEUPLOAD-193) FileNotFoundException thrown by DiskFileItem.write
Date Wed, 25 May 2011 01:52:47 GMT

     [ https://issues.apache.org/jira/browse/FILEUPLOAD-193?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Dan Washusen updated FILEUPLOAD-193:
------------------------------------

    Description: 
Under certain conditions the DiskFileItem.write throws a FileNotFound exception.  It seems
to be when outputFile.renameTo(file) fails.

{code}java.io.FileNotFoundException: /tmp/UploadController/uploading/upload_69651d04_13000a31964__8000_00001651.tmp
(No such file or directory)
        at java.io.FileInputStream.open(Native Method)
        at java.io.FileInputStream.<init>(FileInputStream.java:106)
        at org.apache.commons.fileupload.disk.DiskFileItem.write(DiskFileItem.java:447)
        at upload.UploadController.handle(UploadController.java:90)
        ...{code}

I can't see any obvious reason why the source file (outputFile) wouldn't exist...

  was:

A little digging seems to suggest that the following code is back to front:
{code}in = new BufferedInputStream(
    new FileInputStream(outputFile));
out = new BufferedOutputStream(
        new FileOutputStream(file));
IOUtils.copy(in, out);{code}

It seems to be trying to copy the outputFile (which doesn't exist yet) to the input file.

        at upload.UploadController.handle(UploadController.java:90){code}


Updated description to remove incorrect description of issue.
