is there an absolute max file upload size?

[Jim the Standing Bear-2]

Hello,

I am wondering if there is an absolute max file upload size that if
the file I want to upload exceeds that size, it won't work even if the
maxFileUploadSize in web.xml is set much higher?  If so, what is it?

Because I am trying to upload a 3GB file using the inputFileUpload
control, and web.xml has set the maxFileUploadSize to 5g.  But nothing
happens after I clicked the submit button - it didn't even attempt to
upload the file.  Normally if I am trying to upload a file that
exceeds the max size, it will take some time to suck the bitstream to
the server and then rerender the page; but in my situation, it seemed
to simply give up without even sucking the bitstream first.

Any help would be appreciated.

Hey Jim,
There is a property org.apache.myfaces.trinidad.UPLOAD_MAX_DISK_SPACE
that you need to specify in your web.xml.  This is the max allowable
disk space for your file.  If you go beyond that, it will throw an
exception from its filter.  The default is 5120000 (5000 KB).

thank you for the response, Anuj.  However, I am not entirely certain
if this property applies.  For one thing, I am only using tomahawk,
not trinidad, and also I was able to upload files in hundred-megabyte
range, just not in GB, so if this property was the cause, I wouldn't
even be able to get these files in.

I even enabled debug log on myfaces objects, but it didn't log
anything at all, no exceptions.

Any other possibilities?

Be aware that the servlet spec defines the filesize as an signed 32 bit*, so that unless code is written correctly, there will always be a hard limit of 2GB on upload with size information in advance... since one DOS attack is to upload a file of unlimited size (thereby filling your storage) most good upload components will refuse an unbounded upload (which is what anything over 2GB will look like as a result of the servlet spec)

Not sure if this applies to your case, but an FYI for you anyway

-Stephen

* public int ServletRequest.getContentLength() - returns the length (in bytes) of the content being sent by input stream or -1 if the length is not known (or if the length is greater than 2GB)
