[opencms-dev] FW: FW: Max File Upload Size.

Thu Apr 12 16:35:21 CEST 2012

In the OpenCms

./webapp/WEB-INF/config/opencms-workplace.xml file 

In the node around line 40:

<maxfileuploadsize>-1</maxfileuploadsize>

The default -1 means no limit.

Kind Regards,

Alex.

Okay, so Ive been trawling through the OpenCMS source on a tip from the
Tomcat users mailing list looking for the call to the apache commons
FileUpload lib. Apparently when FileUpload is invoked it takes max size
parameter and they suggested I check to see if it is being set.  I believe
Ive found the code that calls FileUpload around line 536 in the
CmsUploadBean.java file. 

        long maxFileSizeBytes =
OpenCms.getWorkplaceManager().getFileBytesMaxUploadSize(getCmsObject());

Im not a developer but that line suggests to me that there is a setting
somewhere in the Workplace where the maximum size of file uploads is set. 

Can anybody point me in the right direction of where I might find or set
this parameter?

Alberto, thx for responding.

I have since been able to get going the Webkit web browser recommended by
Rüdiger for testing, plus the latest versions of Chrome and Opera both of
which should be able to handle uploads >4GB according to the link you
supplied.

With all of these browsers I found that if I uploaded a file of 1.6GB it
would hang at 99% and not complete. With files of 2GB I would see a negative
percentage in the GWT-Upload progress dialog which would eventually error
with;

==================

Unexpected upload exception occurred.

=========================================

I could be wrong but I personally believe I have now ruled out the browser
as a cause of problem.

One collegue of mine recently commented something about 2GB upload limit due
to browser implementations... You are sure aware of these, but just in case:

http://help.globalscape.com/help/me3/maximum_file_size_for_browser_based_upl
oads.htm
http://www.motobit.com/help/scptutl/pa98.htm

Html 5 should solve this problem. I'm not sure if you are not facing this
challenge.

...and yes, at this point I believe the error is being generated by the
Tomcat6 server although I'm no Java dev so I could be wrong here as I have
nothing other than OpenCMS to test whether the Tomcat6 server can
successfully process a >2GB upload. If I had something basic I could post a
file to at least I'd be able to differentiate between the two.
