Is there any way to check if a file already exists before upload? Otherwise is this can a issue? Otherwise this could become a primefaces issue?

The temporary files which fileupload generates are guaranteed to have unique names. You need to actually save this temp file yourself using the event handler so you can check for such problems yourself.danilo.magrini wrote:Is there any way to check if a file already exists before upload?

Hi @andyba, thx for reply!
Do I have to wait upload the file (e.g. 500 Mb) to then check for duplicate name? This is infeasible!

This can depend on the Browser but in practice the file upload event is only called when the file has been uploaded so, yes you would normally have to wait .danilo.magrini wrote:Hi @andyba, thx for reply!

Why not try it and see what happens?

Description, in this case a file name, shouldn't be a discrimination to skip a process or store data.
Having this in mind, you should agree with PF uploading the file in your temporary directory and renaming it with a unique name.
What you should do is having a kind of md5-checksum, but still, you can do this, obviously, after the file was uploaded.

Luigi
