Uploading large files

[hofmann]

Hi Gurus,

hope someone can help me. I am trying to upload a large file to AS Java CE 7.3 using Web Dynpro Java. While I can upload a file of ~85 MB, it won't work with a file that is larger than 100 MB. Firebug shows me that the connection is immediately aborted after triggering the upload button.

I am now not sure where the error is exactly occuring, maybe in the file upload UI of WDJ, inside WDJ or by a configuration of AS Java. As I do not found anything in WDJ, nor the logs or documentation about a size limit or error message, maybe AS Java is causing this.

In older AS Java releases I had the option to configure the max request header size. This option is gone in NWA 7.3. Anyone knows if there is still a file upload size limit in 7.3 and if so, what is the size limit and how to configure it?

Thanks,

Tobias

Hi Tobias,

In that case, change the configuration of parameter in the Web Dynpro administrator -> "Web Dynpro runtime" setting, adjust the following parameters to your needs (the value in KBytes):

• sap.maxUpload.file   
• sap.maxUpload.session

Thanks and Regards,

Vipin

Hi,

thanks for the reply. These parameters are set to 0 (== unlimited)

Just to rule out that it is WDJ related, I wrote a Portal application. Same result: any file larger than 100 MB is blocked (aborted)

I think I found the parameter that is causing this:

-> The default setting for the size of HTTP requests is a maximum of 100 megabytes.
