Hi,

Can FileUpload plugins check the size and format of files before being uploaded on RAP3 final release in December? If yes, it'll be wonderful, if not, are there any alternative methods doing that?
Thank you!

Best Regards,

David

Hi David,
currently, file upload checks the size during the upload and throws an
exception if maxFileSize is exceeded. I don't think it's possible to do
it before the upload starts (browser security restrictions). What do you
mean by checking format? Add filter to show for selection only files
with given extension? See bugs
https://bugs.eclipse.org/bugs/show_bug.cgi?id=433501 and
https://bugs.eclipse.org/bugs/show_bug.cgi?id=414459 for more details.
Best,
Ivan

Hi, Ivan,

Thank you, I tried setFileSizeMax and it works, but a little pessimistic because users still have to wait until uploading proceeds and fails, if it stops in the very beginning of uploading, could be better, that can reduce server loading and boost efficiency!
Uploading seems to be processed inside org.apache.commons.fileupload.servlet.ServletFileUpload, is it possible to show a message when file size exceeded ? if yes, how or where to put the message code?

Best Regards,

David

Hi David,
did you find any workaround for checking file size before uploading?

We have the same problem about reducing server workload and we hope in some sort of javascript checking before uploading.

Thank you very much.
Vincenzo
