I'm using Jena to import a skos thesaurus and it doesn't work

org.xml.sax.SAXParseException: Content is not allowed in prolog

I would like to import a skos (rdf/xml) thesaurus in Jena model. The skos thesaurus is available in http://www.culturaitalia.it/pico/thesaurus/4.2/thesaurus_4.2.0.skos.xml. I copied that to a local file (in picoFileName) and I used this code to import it in a Model:

    ...
    pico = ModelFactory.createDefaultModel();
    InputStream in = FileManager.get().open(picoFileName);
    if (in == null) {
        throw new IllegalArgumentException( "File: " + picoFileName + " not found");
    }
    pico.read(new InputStreamReader(in), "");
    ...

I receive this error:

The skos thesaurus is validated in w3c rdf/xml validator and in skos validator. What is wrong?

What exactly is in "picoFileName"? Works for me if I call a parser on the downloaded content. Which version of Jena is this?

In picoFileName there is the file full path, and it works because it doesn't throw IllegalArgumentException: I followed it with debug and the crash statement is: pico.read(new InputStreamReader(in), ""); – Alessandra Dec 29 '12 at 12:39

Sorry, there was something wrong in the input file. I copied file content in an other file and it works.
