Re: Help: How to transform XSLTResultTarget object to Document Object for Driver buildFoTree()

[Bracchi Cabannes Christophe <ch...@ac-toulouse.fr>]

Fr : Peut �tre que ceci vous aidera.    J'ai en entr� une chaine xml et
le chemin d'un fichier xsl, je produit d'abord une sortie fo, et ensuite,
� partir de ce flux, je produit la sortie pdf qui repart vers le client.
Ceci ce passe dans le cadre d'une servlet. Ceci marche tr�s bien et
utilise xalan-2.0.0.jar, xerces-1.2.3.jar et fop.jar du package
Fop-0.18.1-DEV.

En : Perhaps, this will help you.  I in entered chains xml and the path
of a file xsl, I produces initially an output fo, and then, starting from
this flow, I produces the output pdf which sets out again towards the
customer.  This this master key within the framework of a servlet. This
goes very well and uses xalan-2.0.0.jar, xerces-1.2.3.jar and fop.jar of
Fop-0.18.1-DEV package.

Code :
    // Production de la source d'entr�e XML
    javax.xml.transform.TransformerFactory tFactory =
javax.xml.transform.TransformerFactory.newInstance();
    StringReader sr = new StringReader (chaineXml);
    javax.xml.transform.Source xmlSource = new
javax.xml.transform.stream.StreamSource (sr);

    // Production de la source d'entr�e XSL
    javax.xml.transform.Source xslSource = new
javax.xml.transform.stream.StreamSource (new FileReader (xsltFile));
    javax.xml.transform.Transformer transformer = tFactory.newTransformer
(xslSource);

    // Production du flux fo
    StringWriter sw = new StringWriter ();
    transformer.transform (xmlSource, new
javax.xml.transform.stream.StreamResult (sw));
    StringReader fo = new StringReader (sw.toString());

    // Transformation du fo en pdf
    ByteArrayOutputStream out = new ByteArrayOutputStream();
    Driver pilote = new Driver (new InputSource(fo), out);
    pilote.setRenderer(Driver.RENDER_PDF);
    pilote.run();

    // R�cup�ration du flux de sorti pdf et envoi vers le client
    byte[] content = out.toByteArray();
    response.setContentLength(content.length);
    response.getOutputStream().write(content);
    response.getOutputStream().flush();
