Q: Progress of implementing new features?
Hi, can someone tell me what the progress is in the implementation of features since the release of FOP0.20.3? Tnx in advance.
incorporating static pdf pages?
Is it possible in xsl-fo when generating a dynamic pdf to add static pdf pages that are contained in a separate pdf file into the final pdf? For example, 2 pages from a pdf file at start of document + dynamically generated xsl-fo + 2 pages from pdf file at end of document TIA, Michelle

HTM Sevlet
Hi, I tried FopServlet example and its works fine for PDF. Is it possible to do the same for HTML that is http://servername/servlet/FopServlet?xml=data.xmlxsl=format.xsldummy=test.html ,I tried to change the code of FopServlet like .. response.setContentType(text/html); Driver driver = new Driver(foFile, out); driver.setLogger(log); driver.setRenderer(Driver.RENDER_TXT); ... But I'm getting unknown formaating object HTML as error. Have any one tried it? Basically I want to convert XML to PDF or HTML using servlets.Do I have to write my own code,or is there out something.

FOP Scalability
* This email and any files transmitted with it are intended solely for the use of the individual or entity to whom they are addressed. * I have FOP 0.20.3 running successfully on my web server and was wondering what the best way to control the scalability of it. There is a possibility that 30 + users may be requesting a PDF page at the same time and as you all know FOP is not too kind on memory usage. The PDF being produced are only 10 pages max so its just the cost of the processing on the web server that is the problem. I have seen ideas about limiting the number of FOP processes running at one time but I dont want to have users waiting for minutes for their PDF page to be displayed. Does any one have any other ideas ?

Re: FOP Scalability
I've never really done this for real, but I think I'd do it like this: On the first HTTP-Request, the job gets sent on the JMS queue. The user receives a Please wait.. page with an automatic refresh and and ID that will be returned to the server upon refresh. Use the ID in a message selector to see whether the job with the respective ID has already finished. If not, send the Please wait... again. I think this should work, but I may be wrong. I'm sure there are others on the list who have done similar things. I think I remember some posts on one of the FOP lists. Browsing the mail archive might be interesting. This is an interesting suggestion - but how does the notification to the Front Controller allow a user to know when the document is ready without some type of polling? We have a similar setup, but a polling applet is being used - which we would love to get rid of.

FOP is primarily a program to format XSLFO into other formats, like PDF. It is not meant to be a more general PDF processor. The iText library http://www.lowagie.com/iText/ can probably help you. You'll probably have to write your own Java wrapper to get your trask done. The iText tutorial has some interesting examples, another one demonstrating how to integrate with FOP is here: http://marc.theaimsgroup.com/?l=fop-devm=102002975028427w=2 J.Pietschmann

You are supposed to try a *bit* harder. The Unicode consortium
http://www.unicode.org
is responsible for allocating character codes. The have a sort
of character names index online
http://www.unicode.org/charts/charindex.html
You'll have to search this, or by The Unicode Book

and look up character codes which you need. I don't speak chinese,
nor do I have any chinese fonts on my computer, I can't help you
any further on this particular problem.
Once you know which Unicode codepoints you are going to use,
locate a font. Look into you Windows Font directory, or, better,
use the character table utility. The character table utility
will tell you for the selected fonts whether it is a unicode
font, and if so, you can pick a character and get the Unicode
code point.
After you've located a font, check with the font directory to get
the windows file name. It should be a TrueType font file ending
in .ttf.
Follow the instructions in docs/html-docs/fonts.html to generate
a font metrics file and register the font with FOP. You'll have
to do this yourself.
Prepare a FO document with some characters you think should be
chinese script, and run it through FOP. It is possible that you
are required to explicitely select the font with the proper glyphs.
If you see sharp signs ('#') where you expect the chinese script
to be this means you've screwed up somewhere.

But I'm getting unknown formaating object HTML as error. Have any one tried it? Basically I want to convert XML to PDF or HTML using servlets. You'll have to gain some more understanding of the underlying technology. The XSL standard consists of two main parts: - XSLT which defines a language for describing transformations from arbitrary XML to other stuff, mainly other XML, and - XSLFO, which defines a language for describing how to layout stuff, mainly on paged media. The first part, XSLT, can be used to describe a transformation of arbitrary XML to (X)HMTL, or, using anther transformation, to XSLFO. The gadgets actually doing such a transformation are called XSLT processors, and Xalan (delivered with FOP) is such a beast (others are Saxon, MSXML, libxslt, there are more). FOP is a processor for transforming XSLFO into a variety of other formats, like PDF, Postscript, Text, or direct rendering into a Java AWT canvas. Therefore, FOP is not the right tool to transform arbitrary XML to HTML. Get the Xalan or Saxon distribution and look at the example servlets delivered there. As others have mentioned, Cocoon is a nice framework which takes most of the dirty Java programming from you. Once you get used to it, your productivity will get a major boost. J.Pietschmann

Register your font using some name, like msmincho, in your userconfig.xml. Write a small FO file using some chinese characters, should work best if you assured they have glyphs in the font. Run FOP.
