Hi Pau,
The schema location in your instance document is a relative URI so this is
likely failing because you're not setting the system ID on the
InputSource. Without providing a base URI the schema loader will fallback
to using the current working directory (the value of the system property
user.dir) as the base URI for resolution.
Thanks.
