Subject fop in a servlet in 0.91beta very different from 0.20.5
Date Fri, 10 Feb 2006 11:30:12 GMT
Hello list.

I'm trying to move from 0.20.5 to 0.91beta.

Here's a problem I'm facing: following the instruction
in the documentation that comes the 0.91beta, lead to
code that doesn't compile.

So I modified it as follows to be able to compile, but
the result I get executing it wrong.. I get an empty
text/html document instead of the expected application/pdf

below's the code in the get/post servlet method and probably
the main difference from the documentation is the parameter
in the Fop constructor MimeConstants.MIME_PDF vs Constants.RENDER_PDF).

Note that this code is the same I used with FOP 0.20.5 with
just a few modification:
1) no Driver, but Fop
2) no driver.run() but transformer.transform()

     protected void processRequest(HttpServletRequest request, 
HttpServletResponse response)
     throws ServletException, IOException {
         try {
             OfferBean offer = (OfferBean)request.getAttribute("offer");
             ArrayList offerPerformances = 
             String s = PdfCreator.getFO(offer, offerPerformances);
             StringReader sr = new StringReader(s);

//            Driver driver = new Driver();
//            driver.setRenderer(Driver.RENDER_PDF);
             Fop fop = new Fop(MimeConstants.MIME_PDF);

             //Setup a buffer to obtain the content length
             ByteArrayOutputStream out = new ByteArrayOutputStream();

             //Setup input
             Source src = new StreamSource(sr);
//            driver.setInputSource(src);
//            driver.run();
             Result res = new SAXResult(fop.getDefaultHandler());

             // ottengo il transformer
             TransformerFactory factory = TransformerFactory.newInstance();
             Transformer transformer = factory.newTransformer();

             transformer.transform(src, res);

             //Prepare response

             //Send content to Browser
         catch (Exception e) {

Any advice/hints?

Thank you and best regards.
