[ome-devel] Download an original file with a remote access

[Olivier Arnaiz]

Hi,

Thank you ... this is perfect.

I have another question :
Is there a way to get the metadata contained in my original file ?
I saw the method : getIMetadataPrx but i am not sure how to use it...

Thanks again
Olivier
