Enhancement Request
I would like to suggest the following enhancement: We use the AWT viewer while creating XSL:FO style sheets to view the output. This is faster then generating a PDF and loading it into Acrobat Reader over and over again. It would be great if the AWT viewer had a Reload button which would reprocess the input. This way we could change an XSLT file and click reload and see the effect the change has.

RE: TIFFRenderer
We would be real interested in TIFF rendering from FOP since our application includes a fax component. My only concern is the use of the AWTRenderer. Whenever we use the AWTRenderer the output (on screen and print) is not as crisp and sharp as the PDF version. The spacing of letters and words is a major issue with the AWTRenderer (as was mentioned in a previous thread). If however a TIFF renderer could be produced that does NOT have these issues we would be real happy to use it. Jim Urban - [EMAIL PROTECTED] Park City Solutions Inc.

Actually, I (biased!) think the present awt renderer is quite good; the character spacings problems within words that existed in previous versions is fixed, and text decorations seem to work correctly. As Jeremias pointed out, I am chasing a new problem - but that one doesn't really bear on awt itself, but shows up only when the awt renderer is used to print. (The problem appears if fop is run w/ -print option or if the print command is invoked on the -awt display dialog.) Offhand, I do not expect the printing problem to show up if the awt renderer were used as the basis for a tiff renderer. We believe the printing problem stems from a java bug around fonts - the character rasterizer seems to be ending up with text strings being improperly sized when it is drawing into a graphics context created by a PrinterJob. There are several related bugs in the bug parade on this matter.

Essentially this is a callback system that has an object draw itself into a PDFGraphics2D during pdf rendering, rather than going through intermediate steps such as svg or Images. I'm fairly pleased with it, though it did turn up some other scalability problems. Initially, plotting one test map took 1.25 minutes; the new version takes about 8 seconds. The original implementation, using the standard fop distribution generated an svg (slow), then loaded the svg (slow), then rendered the svg to the pdf. The new implementation registers some callbacks for the included images, and the callbacks render directly. Memory usage is much better now, as well. We frequently overran the default 64MB with the original implementation, since the dom-based svg generation and reloading both ate up the heap. Now I can generally plot up to E size PDFs (34 x 44), though for complex maps I still run out of heap. Looking into the implementation of PDFRenderer and PDFGraphics2D, it looks like the memory bottleneck with the new implementation is probably the fact that PDFGraphics2D stores its results in a StringWriter, and then that StringWriter is appended to the PDFStream's own ByteArrayOutputStream. This requires twice as much ram as simply writing directly to the PDFStream. True scalability, frankly, will require rendering directly to a file, and keeping as little in RAM as possible. I didn't chase the code to see how difficult that would be, but I figure it's not trivial. The benefits would be enormous - for example, I could plot an entire multi-hundred page map book. On the other hand, the ability to have PDFGraphics2D write directly to the PDFStream should be fairly easy to implement. I'm looking into this now. I did also uncover some bugs. Most prominently, PDFGraphics2D instances spawned from others using createGraphics have their own StringWriters and therefore anything rendered to them kind of disappears off into space. I rewrote it so they share the same StringWriter. In any case, I have a few major changes that may be useful. Are they, and if so should I go ahead and see about getting CVS write access, or does someone want to sponsor me or should I simply send a patch? I have a feeling I'll be returning to the code in the future in any case. Thanks. While I'm finding fop to be kind of a bear, it's still the only real game in town for what I'm trying to do, and I'm getting some great results - we just plotted half the state of new hampshire onto a page the size of a bedsheet, and that's not easy to do without banging your own postscript - add to that the ability to stick these plots on nicely-formatted reports with all the power of FO too and it makes my life a lot easier. -- Paul Reavis [EMAIL PROTECTED] Design Lead Partner Software, Inc.http://www.partnersoft.com - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]

Jeremias, Thank you for your honesty. I'm glad to know its not something we're doing. As for using GhostScript, how did you integrate it into your Java application? The Java application which does our rendering runs detached (as a Windows service). This application runs non-stop, monitoring a database. When it sees a row added to a table it generates a PDF. On an average day this application will generate a couple thousand PDFs.

Subject: 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 :)

RE: FOP AWT Window Shuts Down Application
I thought about that, but then we would have a custom version of FOP. This would mean that every time we upgrade to a new version of FOP someone would have to know to go into the source and make this change and rebuild FOP. I would rather see a more permanent solution implemented such as adding a function to PreviewDialog void setExitOnClose(boolean shouldExit) which would set a flag which would be checked to see if System.exit should be called. I would do this, but I am not an authorized FOP developer and do not have access to CVS either. If someone would offer to check out PreviewDialog.java from CVS and email it to me I will gladly make the change and email back to them to review and check back in to CVS.

RE: Why do you use FOP instead of ...
Our application is a servlet based web application. We have adopted the MVC approach. We found Cacoon over kill, so we implmented our own frame work. Our frame work requires all business components produce XML. We then use XSL:HTML to format HTML output for the browser. It was only a natural next step to use XSL:FO to generate PDF since we already had XML being generated. One of the real blessings of this approach is our clients can customize the look and feel of the application by changing the XSL files without our ever opening a Java source file. It was a BIG investment and learning curve up front to take this approach, but now that we are past that phase, the return on the investment has enabled us to justify the up front expense. Looking back, I think it was a vary sound decission. We are in a position where adding WAP (WML) and a B2b SOAP interface are a natural extension of our framework, not a rewrite. Thank yous go to not only FOP, but Xalan and Xerces for all the XML and XSL support! Jim Urban Product Manager Netsteps Inc. Suite 505E 1 Pierce Pl.

RE: Problems with seeing pdf-files in IE 5.0
you also have to use an url with ".pdf" at the end The url the client is posting to is a servlet which uses FOP to generate a PDF and feed it back to the browser. If the client post a request to myservlet.pdf the server will look for a file called myservlet.pdf and return a 403 when it can't find it. So how do you use a url that ends with .pdf when using servlets?

You are correct, we set the content type to PDF before sending anything back. The problem is how to invoke this servlet and use a .PDF extension when we don't know we are going to get a PDF back.

When the servlet is posted to, the browser has no knowledge of what type of data will be sent back. We have a single servlet which looks at the request and calls the appropriate class to process the request. The request then sends XML back to the servlet. Then based upon the presence of the parameter print in the http request, our servlet attempts to locate the XSL:FO file that maps to the request. If the XSL:FO file is found, we FOP the XML and send back PDF. Otherwise we use a XSL:HTML file and send back a HTML page. Our clients are responsible for providing XSL:FO files for the pages they want PDF prints. The XSL:FO files are optional and may or may not exist.

The blank page at the end isn't so bad, but if there's a way to remove it that'd be nice. Also, does the 'break-XXX' attribute simply add page breaks whenever you reach the end of a page or is it smarter than that? For example, say a table is 3 pages in size. Can you use the 'break-XXX' attribute to make it such that table headers are printed at the top of all 3 pages? My understanding is that the table will simply print across the 3 pages w/ no regards for adding table headers at the top of each page. fo:block break-after=page fo:table... !-- call to template that produces table headers -- fo:for-each... !-- call to template that produces table's contents -- /fo:for-each /fo:table /fo:block - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]

Our application is a web application implemented in Java Servlets. To use the perl approach, we would have to call a perl script from within our servlet, passing the data in memory to the script. The script would then have to modify the data and return it in memory to the servlet. The data can NOT be written to a file without encrypting it. Using XSLT does not change the data. It simply formats the data for display. This formatting is controlled by the client, not our Java code.

Using Xalan. Xalan says unicode 12 (decimal for form feed) is invalid. - If your environment allows it you can also invoke XSLT extension functions to do the replacement. The clients don't want any non-standard (extension) translation functions. - Have you thought of trying the contains(), substring-before() and substring-after() functions recursively to try to locate and extract the text surrounding the form-feed character? It won't be pretty but if you *must* stay in XSLT, it's pretty much your only choice. Yeah, that is ugly. Just some ideas... Thanks, for the ideas. I am currently working with our DBA to see if we can store the contents of each page in a seperate table row. That way we can use xsl:for-each to print each row in a seperate fo:block with a break-after option. Ramin How would I code my XSL to scan a text element for form feeds and insert a fo:block break-before=page and the corresponding /fo:block at the correct places?

Subject: Question on XSLTInputHandler
Hello,
I've looked at the example servlet and found that the XSLTInputHandler
takes as input a java.io.File. However, I am constructing the XML
document dynamically and have it as a java.lang.String in memory. It
seems unnecessary I/O to write it out to a temporary file, just to pass
it to the XSLTInputHandler. Looking at the source of
XSLTInputHandler.java I didn't find any alternate way to call it. What
would the recommended procedure be in this case, where I already have
the XML document in memory?
thanks in advance for any pointers,

I've fixed a few places where I found concurrency issues at one time, but I'm sure there are others I didn't find. When we attempted to use FOP in a multi-processor, multi-threaded Windows NT 4.0 environment, we found that FOP actually worked SLOWER than a single processor and/or single-threaded environment. We ran multiple threads that were responsible for rendering separate documents. We were trying to reduce the elapsed time necessary to render thousands of relatively small (10- 20 page) documents. What we found was running multiple FOP threads on a multi- processor Windows NT box reduced our total throughput. We processed more documents per hour with a single FOP thread than we did with multiple FOP threads. Note that I'm refering to total throughput, not documents per thread per hour. Some analysis pointed to VERY HIGH context switching going on when running two FOP threads on a two processor system. What this told us was that the two FOP threads were fighting over the same piece(s) of memory continuously. This context switching went away when we ran multiple FOP threads on a single processor machine or we ran a single FOP thread on a multi-processor machine. I spent some time looking at the source code, and noticed a large number of statics being declared all throughout FOP. This may be a cause, or it may have something to do in the way the Sun jvm works on Windows. I didn't have the time to dig deeper. I don't remember the exact version of FOP we used for the test. It may have been 0.18.1 or 0.19.0-CVS.

RE: how starting FOP without XML-File
If I understand you correctly, in your servlet you wish to apply an xsl
style sheet (from a file) to an xml string in memory to generate a FO xml
string in memory to run through FOP to generate a PDF in memory which you
want to return to the browser. If that is the case, here are the pieces for
your servlet...
These are class variables...
TransformerFactory tFactory= null;
Transformertransformer = null;
Place this code in your init method to save reading and parsing the xsl file
each time your servlet is called...
tFactory = TransformerFactory.newInstance();
String xslFile = myfile.xsl;
File theFile = new File(xslFile);
Source xslSource = new StreamSource(theFile);
transformer = tFactory.newTransformer(xslSource);
This code goes in your doGet / doPost method and replaces the code from the
previous email...
try
{
String xmlString = ... function to generate your xml String.
Writer out = new StringWriter();
Source xmlSource = new StreamSource(new StringReader(xmlString));
transformer.transform(xmlSource, new StreamResult(out));
out.close();
String fopstring = out.toString();
InputSource foSource = InputSource(new StringReader(fopstring));
ByteArrayOutputStream out = new ByteArrayOutputStream();
response.setContentType(application/pdf);
Driver driver = new Driver(foSource, out);
driver.setRenderer(Driver.RENDER_PDF);
driver.run();
byte[] content = out.toByteArray();
response.setContentLength(content.length);
response.getOutputStream().write(content);
response.getOutputStream().flush();
}
I hope this helps. I wish this example was part of the examples provided
with FOP. Maybe a FOP developer (I'm just a user) can add an example like
this to the FOP package.

pass the input source xml file (text.xml) in the memory. It's possible and
how can I do this?
Thanks
Marc

Hi, I am new to FOP. I have a servlet which dynamically generates XML. I need to apply an XSL stylesheet containing FO tags to generate a FO version of the XML and then I need to run this FO version of the XML through FOP (or Driver) so the servlet can return a dynamically created PDF to the browser. Does anyone have a working example of how to do this? Only the XSL style sheet containing the FO tags used in the initial transform will be on disk. Please help, I have to get this working.

RE: Need Working Sample
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.
