[one-users] OCCI: multipart POST request with java-client

[Javier Fontan]

Hello,

Looking at the log files from your previous email looks like Java
library is sending both parameters (occixml and file) as files in the
post and the web server writes both parameters as temporary files. I
am not sure what is the difference in your java implementation (or
better, the java library) but we have tested the API using curl
command line (in fact we also use curl library to upload files) and
works fine. I'll open a bug to make the server aware of that behavior
and read occixml parameter from a file if that is the case.

Bye
