Need help in writing pdf with more than 1000 pages using fop..
> Hi,
I have just started using FOP. I have a requirement to write a pdf file
with more than 1000 pages.How can I do that? I am directly creating a
XSL-FO string to create a pdf document and concatenating that into a big
string, I know it wrong, Is there any other way?. Basically, we generate
documents for multiple participants at the same time and write all their
data into a single pdf file. Here is an example:

Actually, for me, that's even another reason for using XSLT. But in the
end, you have to live with your solution.

What I meant was to create a common XML format for the contents (i.e.
defined by an XSD), independent of how contents are supposed to be
styled. You'd have different XSL style sheets then that operate on that
same XML format to produce the different styles of layout in FO XML.

Thanks, but we will not know anything about the look of the documents, it can be in any style.
We are tryng to generate Statements(with bar chart, pie chart, texts and images), Check documents & regular documents(with text and images) and
so, it is very difficult for us to create a pre-defined common XSL for all these types of documents.
Assume that I have a pre-defined XSL and am creating a XML documents at runtime, how do you flush out the contents to the pdf documents without keeeping them in memory and append all the remaining participants data to the same pdf?. We may use Inetsoft or iText or any other 3rd party software to generate the pdf if we are not able to use fop.
Thanks

Hi,
what about having an intermediate XML format for your contents that is
common to all of your clients, and having different XSL style sheets for
producing the actual XSL-FO? You might be able to factor out common
stuff into an included XSL.
I might have not fully understood your requirements, though.

Thanks.
But the pdf document we create is NOT of the same style everytime, we
are creating documents of different look and feel (but all are pdf)
depending on the document name for a participant. Actually, I missed out
our data style. It should be:
Participant1 DocumentA Client1 Plan11
Participant2 DocumentB Client1 Plan11
Participant3 DocumentC Client2 Plan21
Participant4 DocumentA Client2 Plan21
.....
.... and so on. Eventhough Participant1 and 4 are using the same document
name, since they are under different client, their document definition
may be entirely or slightly different.
I don't think we can have one common StyleSheet to print pdf for all
types of documents and that is why I am directly creating XSL-FO.
Thanks

Please take a look at the embedding examples:
http://xmlgraphics.apache.org/fop/0.95/embedding.html#examples
They give you hints on how to implement the process in the most
efficient way.
It's bad practice to generate XSL-FO directly in code. It's messy and
hard to maintain. If you just send the participant data to a SAX stream
(define your own basic XML format with just the participant data, no
layout), you can separate out the layout logic into an XSLT stylesheet
that will take your XML format and turn it into XSL-FO. That keeps your
Java code clean and allows you to more quickly change layout stuff if
you need to. It also has the added benefit that you can do something
else with the XML data. For example, another XSLT stylesheet could turn
your participant data into HTML. The generation of the participant data
is practically equivalent to the ExampleObj2XML on the page indicated
above.
If you stay on the SAX level, you can avoid building up the full
participant document in memory. FOP will rather process the content as
it comes in as individual calls to the SAX ContentHandler.
If you can put each participant in a separate page-sequence you'll allow
FOP to run at very little memory usage. You can basically generate an
unlimited number of pages that way. Each participant is automatically
"flushed" to the PDF file that way.
I hope that helps.
