RE: FOP WARNING - Please Help!
I downloaded and built the latest CVS. When I tried to use the XSLTInputHandler, my error switched from the weird one I was getting to yet another null pointer exception. That got me thinking maybe I should just try doing the simplest transform of all time and see if it isn't something with my stylesheet. Anyway the problem was I only had the xsl namespace defined in my stylesheet root element and not the fo namespace. xsl:stylesheet xmlns:xsl=http://www.w3.org/1999/XSL/Transform; version=1.0 xmlns:fo=http://www.w3.org/1999/XSL/Format; (missing) I probably should have known this. I think someone even mentioned it, but I wasn't sure what they were talking about. Anyway, the good news is that after three days of fiddling I feel like I know FOP pretty well. I also have a much better grasp of SAX and DOM. Again, thanks for all your help. You probably haven't heard the last of me. -Matt Savino -Original Message- From: Beer, Christian [mailto:[EMAIL PROTECTED]] Sent: Tuesday, September 25, 2001 11:32 PM To: '[EMAIL PROTECTED]' Subject: AW: FOP WARNING - Please Help!

I downloaded Fop-0.20.1-src.tar.gz on 9/17/01. Is there something more recent? I only ask because my ridiculous company still hasn't restored our internet access since Nimda. I would also be happy if I could get render(dom) working when applied
FOP WARNING
I am trying to generate PDFs using FOP-0.20.1. The input files are xml and xsl files I am using JRun3.0 with java1.2.2 Here is the error I get WARNING: Unknown formatting object ^root Anybody any ideas? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
Re: FOP WARNING
Hi,
I want explain that the error:
WARNING: Unknown formatting object ^root
for me is locate in stylesheet
Instead the error that
Ihave encountered it was on my XML
I think that the parser didn't know my element root!
For this reason I haven't used the code in fop home
and I have perform first the transformation
and then the driver

I have solved the problem using 2 phase:
1) generate the transformation using XSLTrasform, Xalan1Transform etc...
(you can choose)
code:
XSLTransform traXSLT = new XSLTransform();
traXSLT.transform(urlXML, urlXSL, urlFoFile);
You can choose 4 transform type (see the api documentation)
2) Apply the result at the driver
FileInputStream file = new FileInputStream(urlFoFile);
response.setContentType("application/pdf");
Driver driver = new Driver(new InputSource(file), out);
driver.setRenderer(Driver.RENDER_PDF);
driver.run();
byte[] content = out.toByteArray();
response.setContentLength(content.length);
response.getOutputStream().write(content);
response.getOutputStream().flush();
THIS CODE WORK FINE!!!

Re: FOP WARNING
Okay,
The example that I give is only to explain
that you can perform the PDF in two distinc phase
1) perform a trasformation
2) use driver
You can use the "tranform method"
with input like Dynamic xml (Dom Document) or urlXML
and getting out a fo (Dom Document) or Writer object
YOU HAVE A LOT OF TRANSFORM TO USE!!
YOU HAVE TO SEE THE APIDOC FOR THE
COMPLETE DOCUMENTATION
For example in my project I use
xalan transform and with some
conversion I use the Fop driver
and my XML is dynamic.
WITH Transformer XALAN:
StringWriter SstringWriter = new StringWriter();
/* this is the fo file */
StreamResult SstreamResult = new StreamResult(SstringWriter);
transformer.transform(SstreamSourceXML, SstreamResult)
/* convert the fo file in a right format for driver
ByteArrayOutputStream outPDF = new ByteArrayOutputStream();
SResult = SstringWriter.toString();
ByteArrayInputStream str = new ByteArrayInputStream(SResult.getBytes());
Driver driver = new Driver(new InputSource(str), outPDF);
Is this performance? I think yes!!

RE: FOP WARNING
Two problem with this approach. First, you are using a lot of memory to store intermediate XML result in a string buffer. Second, you have to parse that XML again (FOP will do it for you, but it takes time). A better solution, as I already said before, is to register FOP as a receiver of SAX events fired by XALAN on the first transformation - this was you eliminate both problems and do all your work in one pass. Just create a Transformer from the stylesheet and do // 3. Create FOP driver and set rendering mode and output stream org.apache.fop.apps.Driver driver = new org.apache.fop.apps.Driver(); driver.setRenderer(driver.RENDER_PDF); driver.setOutputStream( whatever you writing to ); // 4. Create SAXResult based on FOP Driver content handler which // will accept SAX events and build FOP tree javax.xml.transform.sax.SAXResult saxResult = new javax.xml.transform.sax.SAXResult( driver.getContentHandler() ); // 5. Use the Transformer to transform an XML Source and send the output // to a Result object. //Implicitely it will create the FOP tree by firing SAX events transformer.transform( whatever XML source you have, saxResult ); YS -Original Message- From: Semprini Davide [mailto:[EMAIL PROTECTED]] Sent: Monday, September 24, 2001 9:42 AM To: [EMAIL PROTECTED] Subject: Re: FOP WARNING Okay, The example that I give is only to explain that you can perform the PDF in two distinc phase 1) perform a trasformation 2) use driver You can use the tranform method with input like Dynamic xml (Dom Document) or urlXML and getting out a fo (Dom Document) or Writer object YOU HAVE A LOT OF TRANSFORM TO USE!!

Anybody see anything that I am doing wrong?
