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

Wed Apr 11 15:20:53 CEST 2012

Okay, so I've 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 I've found the code that calls FileUpload around line 536 in the CmsUploadBean.java file.

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

I'm 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_uploads.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.
