RE: Need Working Sample

[Michiel Verhoef]

Just a thought but what you seem to want is the XML file processed by XSL
(which can be on disk).

Have you checked the docs/examples for Xalan, the XSLT processor oncluded
with FOP?
Because that is what you've been asking for: how dow I process my XML file
using my XSLT
stylesheet.

Sorry, no Java programmer so I can't give any techie tips but I'd go and
have a look at the Xalan
docs and examples if I were you..

Good luck,

Michiel

$ 
$ 1. The XML does NOT exist on disk!  It is in memory only, and

$ 
$ 2. This is a high traffic web application.  Starting a new

Re: Need Working Sample

[Karen Lease]

Hi again,

Just to make sure I wasn't talking through my hat, I tried out what I
told you to do. It works OK for me. I attached a short java file
(TestXSLT) which I tested with your xml and xsl. Here is what I used to
run it (TestXSLT.class in the local directory).

java -cp
.:build/fop.jar:lib/xerces-1.2.3.jar:lib/xalan-2.0.0.jar:lib/batik.jar
TestXSLT prueba.xml prueba.xsl

It looks like you had all the pieces, but maybe not in the right order.

If it works, I'll collect the beer next time I'm in Geneva (unless
you're in Paris (France, not Texas!) before then.

Salut,
Karen

Re: Need Working Sample

[Dave Frankson]

I've been doing XML+XSL+FOP transforms in a servlet for months.  I have
a servlet that takes an xml and an xsl parameter (either a url to a file, a
url to a jsp page that dynamically generates the xml, or an ObjectID that
where the Object is taken from an Object database and transformed to xml in
memory).  It then passes it through xalan and if necessary fop and returns
either xml, html, or a pdf.

Here is some code adapted from that servlet:


String xmlData = ""; //--- This is your xml in memory
String xslData = ""; //--- Tis is your xsl in memory

StreamSource xmlSource = new StreamSource(new StringReader(xmlData));
StreamSource xslSource = new StreamSource(new StringReader(xslData));

StringWriter transformOut = new StringWriter();

StreamResult xsltOut = new StreamResult(transformOut);

 try {
  Transformer transformer = factory.newTransformer(xslSource);
  transformer.transform(xmlSource, xsltOut);
 }catch(Exception e) {System.out.println("XSLT Exception: " + e);
e.printStackTrace();}


  ByteArrayOutputStream pdfContent = new ByteArrayOutputStream();

   InputSource fopIn = new InputSource(new
StringReader(transformOut.toString()));

   response.setContentType("application/pdf");
   response.addHeader("Content-Disposition", "inline; filename=report.pdf");
   BufferedOutputStream out = new
BufferedOutputStream(response.getOutputStream());

   try {
String parserClassName = System.getProperty("org.xml.sax.parser");
if (parserClassName == null) parserClassName =
"org.apache.xerces.parsers.SAXParser";
XMLReader parser =
(XMLReader)Class.forName(parserClassName).newInstance();

parser.setFeature("http://xml.org/sax/features/namespace-prefixes";,
true);
String version = Version.getVersion();
Driver driver = new Driver();
driver.setRenderer("org.apache.fop.render.pdf.PDFRenderer", version);
driver.addElementMapping("org.apache.fop.fo.StandardElementMapping");
driver.addElementMapping("org.apache.fop.svg.SVGElementMapping");

driver.addElementMapping("org.apache.fop.extensions.ExtensionElementMapping"
);
driver.addPropertyList("org.apache.fop.fo.StandardPropertyListMapping");
driver.addPropertyList("org.apache.fop.svg.SVGPropertyListMapping");

driver.addPropertyList("org.apache.fop.extensions.ExtensionPropertyListMappi
ng");

driver.setOutputStream(pdfContent);
driver.buildFOTree(parser, fopIn);
driver.format();
driver.render();
   }catch(Exception e) {System.out.println("FOP Exception: " + e);}

   byte[] pdfDoc = pdfContent.toByteArray();

   response.setContentLength( pdfDoc.length );
   out.write( pdfDoc);
  }
   out.flush();
   out.close();

Applying XSL to your XML in memory should be fairly easy. The
transformation APIs in JAXP handle this. then just edit the servlet code to
handle something other than a file stream. I got this to work without much
problem a while ago. My code is appended below -- I think it worked with
0.17, haven't checked it in a while. It differs only slightly from the
original. The fo data comes in an HTTP parameter called "fo", though you
can change the name. It loads this all into the String called fo. Then when
it sets up the driver, instead of passing it a FileInputSource, it passes
it a StringInputSource derived from the fo String.

I dimly recollect that the Driver interface changed a lot in 0.18 so some
of these methods may now be hidden, i.e. not called directly in the
servlet, but if you manually configure your driver, changing the type of
input source you hand it should not be hard.

RE: Need Working Sample

Hi Erik,
 I have tried your stuff, but it still gives me the same problem i
have since two days after I try to instantiate the parser:

javax.xml.transform.TransformerConfigurationException: Namespace not
supported by SAXParser
Error msg: null

At the risk of looking abusive, could someone take a look at the xml and xsl
files (they are really short examples that work with Fop as a line command,
and I'll invite a beer to whomever comes to Geneva (CH, not IL) to pick it
up)?

They are attached once more.

Really thanks, and sorry to know that Jim cannot use my non-elegant
solution. I am fighting this stuff for days also and I have to finish my
project by next Friday.

Hi Gustavo,

the following works great:

  ByteArrayOutputStream out = new ByteArrayOutputStream();
  Driver driver = new Driver();
  driver.setRenderer(Driver.RENDER_PDF);
  InputHandler inputHandler = new XSLTInputHandler(xmlFile, xslFile);
  org.xml.sax.XMLReader parser = inputHandler.getParser();
  driver.buildFOTree(parser, inputHandler.getInputSource());
  driver.format();
  driver.setOutputStream(out);
  driver.render();

  response.setContentType("application/pdf");
  byte[] content = out.toByteArray();
  response.setContentLength(content.length);
  response.getOutputStream().write(content);
  response.getOutputStream().flush();

This example lets the servlet stream the result directly to the client
browser. If you want to have the pdf file on your disk instead, just write
use an other output stream!

It currently does not work for IE5.5, but I'll check the hint of Alex
McLintock earlier in this list.

Hope this helps you out,

What is xmlFile?  Please don't tell me its a file.  My XML is NOT in a file,
its in a StringBuffer in memory, not on disk.

Hi Gustavo,

the following works great:

  ByteArrayOutputStream out = new ByteArrayOutputStream();
  Driver driver = new Driver();
  driver.setRenderer(Driver.RENDER_PDF);
  InputHandler inputHandler = new XSLTInputHandler(xmlFile, xslFile);
  org.xml.sax.XMLReader parser = inputHandler.getParser();
  driver.buildFOTree(parser, inputHandler.getInputSource());
  driver.format();

  driver.render();

  response.setContentType("application/pdf");
  byte[] content = out.toByteArray();
  response.setContentLength(content.length);
  response.getOutputStream().write(content);

RE: Need Working Sample

[Marc Lindsay]

You are not alone Jim,

I have exactly the same need than you (but I also want the XSL in a string
buffer).  I'm waiting impatiently the answer of your question.
Unfortunetly, I don't have any hint to provide.

Sorry, but this does not work for two reasons.

1. The XML does NOT exist on disk!  It is in memory only, and writing it to
disk is NOT an option.

2. This is a high traffic web application.  Starting a new JVM to process
FOP is too costly.

There must be a way for this FOP thing to read raw (data only) XML (in
memory) apply an XSL style sheet to add the FO tags, then format the PDF and
return it to a browser.  I can't believe I am the first person in the word
to need to do this.

If I seem upset, I'm sorry.  But I have been fighting with FOP since last
week to get it to do this.  FOP works great for taking FO files and
converting them to PDF files, but that's not what I have to do.  I have a
deadline to meet and I have wasted a week trying to get FOP to work.

Hi Jim,
I have exactly the same problem, and I've just found a non
elegant, working solution:

I generate my XML file, and then call the command line Fop from within my
servlet:

Runtime.getRuntime().exec(new String[]{"java.exe", "-cp",
"c:\\fop\\Fop-0.18.1-DEV\\fop.jar;c:\\fop\\Fop-0.18.1-DEV\\lib\\w3c.jar;c:\\
fop\\Fop-0.18.1-DEV\\lib\\xalan-2.0.0.jar;c:\\fop\\Fop-0.18.1-DEV\\lib\\xerc
es-1.2.3.jar;c:\\fop\\Fop-0.18.1-DEV\\lib\\jimi-1.0.jar",
"org.apache.fop.apps.Fop", "-xml" , "c:\\prueba.xml", "-xsl" ,
"c:\\prueba.xsl", "-pdf" , "c:\\prueba.pdf"});

As I said, it is NOT elegant, but after sweating for days with problems of
all type doing the elegant thing, I get my beautiful PDF on disk.

Of course you should adapt the names of trhe directories  and the xml and
xsl files.

Cheers,
   Gustavo

PS: if someone has an elegant solution I would be happy to use it too.

RE: Need Working Sample

[Jim Urban]

The FopServlet reads a .fo file.  This is of no use to me.  I will
dyamically generate XML contianing only data.  This XML will be in a
StringBuffer.  I first need to apply an XSL sytle sheet to this
StringBuffer, generating a new XML stream (IN MEMORY).  This new (IN MEMORY)
XML stream then needs to be ran through FOP to generate a PDF stream which
will be sent back to the browser.  The embed sample also shows how to
process .FO files.  This is not what I want  The ONLY file that can be
on disk is the XSL file which contains the FO tags to apply to the XML data.

There is a FOP servlet example in the distribution of FOP :

/docs/examples/embedding/FopServlet.java

I think it will answer all the beginners questions.
See the example section on the FOP site to see all pre-answered question
you might have in your beginning journey.

The problem with that example is that it assumes that you already have the
.fo file, the production of which I've found to be the difficult part.
