Re: Exploring the FOP API design space
cruft ? -- David B. Bitton [EMAIL PROTECTED] www.codenoevil.com Code Made Fresh DailyT - Original Message - From: J.Pietschmann [EMAIL PROTECTED] To: fop dev [EMAIL PROTECTED] Sent: Friday, May 31, 2002 5:34 PM Subject: Exploring the FOP API design space Hi foppers, I know I should provide code instead of talking, but then... The current FOP API suffers from a variety of deficiencies - unexpected statefulness (most horribly embodied in XSLTInputHandler) - weak abstraction of input and output channels - incomplete separation of abstraction levels. - cruft :-) Some points I think should be followed on design of a new and hopefully better API: - Atomic initialisation. After creating a processor, it should be ready to run. Mandatory parametrisation data should be passed either to the constructor or the method(s) running the formatting process, everything else should be initialised from sensible defaults. - No file names, anywhere. Strings representing ressources are always URLs, on the command line, in the config file everywhere. In the API, use java.io.File if files are deemed necessary. - No baseDir. Define a baseURL concept. Pass all URL through a resolver. - Better abstraction of input and output channels. Whether only an avalon component API is exposed or whether there is an avalon-free API and a separate avalon component is a matter of taste. In either case, I'd like to have the possiblity to run a FOP core without access to external config *files*, this means I can create a new Driver() and can pass all config data by java properties, service definitions and by using a user written Configuration class passed to the Driver.configure() method for everything too complex to be passed as properties and services (i.e. user font config). A FOP default Configuration class could read a system and a user config file. From what I've gathered from Avalon this is already implemented this way there. However, I'm not sure, and I'm not dogmatic about this. The problem I have is the design space for abstracting input and output channels. = Input = For input, we have the javax.xml.transform.Source stuff which provides a nice unified encapsulation of SAX, DOM and serialised XML streams as well as SAX and DOM itself. The nice part about the j.x.t.Source stuff is that it shields the user from as much of the lower level XML stuff as possible, in particular from setting up a parser in the common case of having serialised XML as input. Design choice 1: Use j.x.t.Source as FOP input. Implement a o.a.f.stream.XSLTStreamSource as a j.x.t.s.StreamSource subclass for providing XSLT power. (see end of message for an interface proposal) Choice 2: Provide SAX and DOM as input (getContentHandler() and render(DOM)) Choice 3: Provide (more precise: expose) both. Redundant, but, well... = Output = Next problem: output. We have two rather radically different output types: byte streams and GUI panels. A really stumbling block is that the object the output is written to is volatile, it is likely to change with every rendering run, while the kind of renderer as well as the renderer specific configuration is more stable. This has profund implications for the API design. Choice 1: The interface is at the final output level. This means render()/run() methods for each of the classes: render(OutputStream) // for PDF, MIF, PS, ... run(UserAgent) // for AWT... We could add a print() method if necessary. Rationale for choosing the method names: render() means the input FO is rendered to a byte stream. Run() means, the UserAgent is started and the user can interact with it. The run() method will return if the user somehow ends the interaction process and shuts down the UserAgent. Do I interpret the current state correctly? This choice implies the renderer and any configuration data specific to the renderer has to be passed to the Driver (processor) through the Driver configuration methods. Because some renderers can be assumed to have a lot of renderer specific config data which warrants a structure imposed on it, I'm not very fond of the whole idea. Choice 2: The interface is the renderer. This means the renderer object has to be created by the user explicitely. The advantage is that the renderer configuration can be designed to fit the renderer rather than to be passed through a more generic interface at the Driver. Also, renderer configuration and the renderer independent processor configuration are better separated, which might be a good idea, in particular for people who want to render the same FO to several different output formats. In this case, a typical code snipped would look like Processor p=new Processor( new ProcessorConfiguration(new File(myconfig.xml))); Renderer r=new PDFRenderer( new PDFRendererConfiguration(cocoon:/myPDFconfig.xml))); p.render(new

Re: embedded FOP from Document to PDF
ok, here's what ya want to do. when you perform a xalan xslt transform, you can specify a SaxResult as the output object. When you instantiate the SaxResult object, you pass a ContentHandler object to the constructor. Ok, so the question is, what does this have to do with you. fop's transformation engine is sax driven. we are given access to the underlying transformation engine, a SAX ContentHandler by calling getContentHandler() on the Driver object. We then pass the return value to the SAXResult constructor. the nice thing about doing it this way, is that as xalan transforms the xsl, it fires SAX events right into fop. therefore, it's essentially generating fop's output (pdf for example) at the same time the xml is transformed in xsl:fo by an xslt stylesheet. the line of code from my app looks like this: ... transformer.transform( new DOMSource( doc ), new SAXResult( driver.getContentHandler() )); ... also, by doing this, you do not need to pass any document or inputsource or even call render(), because it all done once the transform finishes. lemme know if you need an example. -- David B.

Are you sure you don't have something else which causes the parser

With the following code
try {
Driver driver=new Driver();
driver.setRenderer(Driver.RENDERER_PDF);
driver.setOutputStream(...);
Transformer transformer=TransformerFactory.newInstance()
.newTransformer(new StreamSource(new File(stuff.xsl)));
transformer.transform(new StreamSource(new File(stuff.xml)),

Re: Fw: Re: Rendering from a Document
Ok this is what I'm doing: I produce an XML file from data stored on a mainframe. The XML is generate in a VB object. The XML is passed up to an ASP page that makes a Low Level API SOAP call, using MSSOAP Toolkit 2.0, to my PDF server. The PDF server is running Tomcat 4/Apache SOAP 2.2. On the PDF server, I receive the XML as literalxml in the envelope, fetch a stylesheet, pass the Element object to a Xalan 2.3 transformer (wrapped in a DOMSource object), and then transform the XML into XSL:FO objects. Now I have a Document object that was returned from the transformer wrapped in a DOMResults object. The next step is where the problem lies. I want to pass the Document to a Driver, but I get the dreaded NullPointerException. Most of the time, the XML is will be small ( 5 - 7K), but there is a potention for an account to have 5 to 10 thousand transactions in a day, and we store up to 63 days of data (a single transaction in XML is 594 bytes, therefore a 630K transaction XML file would be 374MB, plus some extra data at the top). So you can see what I have the potential to deal with. What I don't even know is how FOP will handle this. The XSL:FO file is sure to be much larger than 380MB. I transformer a 6.66KB XML file and it produced a XSL:FO file of 16.2KB. If we use that as a benchmark, than the same 374MB would become 909.8MB. That's a whole lot of RAM, not to mention what FOP is going to use to store the rendered PDF. I'm hoping that someone can poke a hole in these numbers (please), because this is getting to look a whole lot bigger than expected. Obviously performance and resource utilization are major concernes (like when are they not?). Obviously SAX for this would be faster because it wouldn't require loading the entire XML contents into memory. So, now is here the questions come in. Do I return from the transform a SAXResults? Also, how do I effectively handle the incoming XML into the SOAP method? I would prefer to send the XML in literalxml format so the and are HTML encoded (increasing the size of the content even more). Where do I go from here?

Re: Re: Rendering from a Document
Here's an update, and a potential bug. The NPE was actually resulting from an improper transformation of the XML. The Element object passed in by Apache SOAP needs to promoted to Document object status prior to being passes to the transform in a DOMSource object. This is accomplished with the follow: Transformer transformer = tFactory.newTransformer( new StreamSource( xsl_url ) ); DocumentBuilderFactory dBuilderFactory = DocumentBuilderFactory.newInstance(); DocumentBuilder docBuilder = dBuilderFactory.newDocumentBuilder(); Document doc = docBuilder.newDocument(); Node newNode = doc.importNode( element, true ); doc.appendChild( newNode ); transformer.transform( new DOMSource( doc ), new SAXResult( driver.getContentHandler() )); This produces a nice PDF. I notice that by doing this, I do not have to call the run() method, so therefore I'm assuming that this saves a step in the entire rendering process. Please correct me if I'm wrong, but am I to believe that the PDF is being rendered as the SAX events are being fired by the transformer? By this, it seems like this should save me alot of memory usage because I won't have to hold the XSL:FO output in an object. I am very happy with the way this is turning out. I promise an article on it as soon as I'm finished.y -- David B.

Making iText (optionally) output xsl:fo would greatly extend its potential applications and make it squarely standards based.

Re: Acrobat 5.0 Error
Do your documents employ any encryption? Also, why
aren't you opening the new window with the url to the servlet in the first
place?
Also, I'm confused as to the use of the cookie (personnaly,
i'm fond of cookie monster myself). I can see that you are "serving" the
pdf from within the servlet. Try, just for kicks, saving it to disk, and
then sending down that Jscript. If anything, I'd be curious to see what
happens.
I code web for a living, so, any questions, feel
free...

Subject: RE: Acrobat 5.0 Error
David,
Thank you for the
advice. We are handling
thePDFsa little
differently, however, and are running on
Apache.
In the JSP file that displayscontent in the browser, we have the following
link withina form
nameddocumentmanagementsearchnavigation:
a href="#"
img
src="javascript:void(0);" width="29" height="60" border="0" alt="Print
Unprinted Approved Documents in the list."/a
Here
is the batchPrintDocument functionin thejavascript
file:
function batchPrintDocument( form
) { var option =
"HEIGHT=400,WIDTH=700,scrollbars=1,status=1,menubar=1";
newWindow = window.open("BatchPrint.html", "BatchPrintDocumentWindow",
option); result =
getCookieData(); if (result ==
"") {
result = 0; document.cookie = "app=" +
result; }
else {
result = parseInt(result) + 1;
document.cookie = "app=" + result;
} var source =
"Servlet?actiontotake=batchprintdocument.pdfcookie="+result;
newWindow.location = source;
newWindow.focus();
return false;
}
We
define the batchprintdocument.pdf action in the Servlet. The batch
function in the servletactually builds one large document that consists
of many smaller documents. For instance, a user can print one individual
report or click on the batch print icon to print all of the reports. She
is able to print one doc OK, but receives the error when printing batch
printing all documents even when there is only 1 or 2 docs to be batch
printed.
This
featureis working well, except onher computer. We suspect it
is her configuration.
Thanks
again!!

How is the PDF being served to the user? Is it
coming from an ASP page and being Response.BinaryWrite'ed? The best
work around that I'm using for this problem is this:
I persist the file on the server, then send this to the
browser:
htmlhead
script language="javascript"
!--
window.location.href='%=path%'
//--
/script
/headbody/body/html
This way, IE will go fetch the file itself. If you
are using IIS, save the docs in their own folder, then go into the IIS
setting, and enable content expiration (it's on the HTTP Headers tab) just
for that folder and set it to expire immediately. If you don't do
this, IE will keep pulling the PDF from it's cache if you re-use
filenames.

Hello!
Thanks in
advance for your time and help.
I know this is
not exactly an FOP issue, but will be very helpfulto the folks who
are already in a production environment.
I have a user
running WIN NT and views FOP-generated PDFs in Acrobat 5.0 within Internet
Explorer.
When she opens
the PDF, she receives the error:
File does not
begin with :%PDF...
She receives a
dialog box then clicks OK and gets a blank screen. In our offices,
we are able to view the same documents in Acrobat 5.0 with no
problem.
At this time, I think it is a problem on
the user'sPC. I am
hoping someone has seen this type of problem before. I am able to
see that, on my computer, the PDF starts with :%PDF. Why is
her Acrobat interpreting it differently?
Thanks!
Rachael
P.S. I
also had her try the option toNOT view it in the browser. I
had no success with this
either.

Re: userconfig.xml
In the context of a servlet, where would I place userconfig.xml file relative to the webapps dir, and what path would I use to retrieve the file.

the marked area([X]) will turn black temporarily. The area that

HowTo Render PDF from XML string and XSL file
I have spent some time looking at the embedding sample, and I have some questions. I have successfully implemented FOP as a WebService having the XSL-FO data posted to the service and the service rendering the file onto the local machine. Now I want to do the XML/XSL to XSL-FO transform in the WebService. I noticed that the transform occurs in the XSLInputHandler. This then allows for an InputSource and XMLReader to be available to the Driver.render() overloaded method. The unfortunate part is the XSLInputHandler constructor only takes File object, no stream. I'd like to avoid bouncing the XML data off the disk just to statisfy this requirement for using XSLInputHandler. So, my question is this, how can I arrive at the same results, an InputSource and an XMLReader interfaced object for Driver.render()? Or better yet, what I'm asking is what is going on inside XSLInputHandler that I can slurp out into my code. Tx :) -- David B.

Re: java.util.HashMap to com.sun.java.util.collections.HashMap
There are number of ways to make Java available across COM, but as far as i
can tell, they all use the local VM that's installed on the machine, and it
needs to be running. This way, it's compiled into the DLL, along with _all_
of the other classes that are used (from xalan, etc.). I just d/l'ed the
latest CVS snapshot, and the build breaks on:
[javac] E:\xml-fop\build\src\org\apache\fop\svg\PDFGraphics2D.java:1196:
nested class org.apache.fop.svg.PDFGraphics2D. PDFGraph
icsConfiguration is an abstract class. It can't be instantiated.
[javac] return new PDFGraphicsConfiguration();

java.awt.image.VolatileImage createCompatibleVolatileImage(int, int)
from class java.awt.GraphicsConfiguration.
[javac] static class PDFGraphicsConfiguration extends
GraphicsConfiguration {

does anyone know why this is? I am using all of the latest version of the
dependent libraries, Xalan, Xerces, etc. I wanted to make sure I could
build the classes before I started the search and destroy mission to find

You can use also the java-plugin (IIRC) to make java objects used as OCXs.
There is also a project on IBM alphaworks, and one on Sun javasoft to make
EJBs used in such a way.
Maybe these can help.

I suspect that supporting JDK 1.1 with the current FOP would require dropping image and SVG support as well as significant coding changes. FOP has come a long way since the last version that supported JDK 1.1, so it would probably make a lot more sense to apply your efforts to getting a JDK 1.2+ environment for your COM DLL.
