InputStream and OutputStream use in FOP servlet

[Solange Desseignes <sd...@calendra.com>]

Hi,

I use FOP to generate a PDF file from an XML file With a XSL/FO transformation.
The generation is made in a servlet.

Actually, I use the method described in the FOP Web site:
Driver driver = new Driver();
driver.setRenderer(Driver.RENDER_PDF);
InputHandler inputHandler = new XSLTInputHandler(xmlFile, xslFile);
XMLReader parser = inputHandler.getParser();
driver.setOutputStream(new FileOutputStream(outFile));
driver.render(parser, inputHandler.getInputSource());

But, I want to use InputStream instead of File for xslFile and xmlFile (to use in war in Tomcat).
And, I don't know how do this !

Moreover, I have fonts configuration.
For the same reason, I can't use:
userConfigFile = new File(userConfig);
options = new Options(userConfigFile);


Can anybody help me ???
Thanks.

Implement your own xsl transformator class and put something like this in it:

public void transform(Document document, OutputStream out) {
	try {
	    Source source = new DOMSource(document);
            TransformerFactory factory = TransformerFactory.newInstance();
            Transformer transformer = factory.newTransformer(new
StreamSource(new File(mStylesheet)));
	    transformer.transform(source, new StreamResult(out));
	} catch (Exception e) {
	    e.printStackTrace(System.err);
	}
}
