Problems concerning FOP: / by zero

Ali Sahin

Hi there,

I'd like to transform a XML-File to PDF.

The XML-File ist build like followed:

You expect the folks here to claw over 400 lines of your
poorly trimmed example to find the error?

The best way to get help is to trim back the example
to a point where it is the *shortest* practical
demonstration of the problem.

One way to trim this example would be to remove every..
<!ENTITY cent "¢">
...but one. If you can get it to work (or fail) with one
entity defined, you can then extend it to all of them.

It's written in Java, that's what. When a Java application hits an error
it gives you a trace of the location in the Java code where the error
occurred, instead of giving you the location in your document where it
occurred, just to be obtuse. This is because Java programmers think it
is far more likely that their code is at fault than your document :-)

[Sorry, just being cranky. There are plenty of Java applications which
behave sensibly, but also plenty that don't.]

Andrew Thompson gave you very good advice to make a simple test case. I
really recommend that if you expect people to help you.

However, I've copied your info into two files and processed them with
xsltproc, which give an almost empty temporarily FO file, so I guess
your XSL stylesheet has a problem. Maybe your FOP gives the devided by
zero error because of this, I don't know, like Peter explained, java
programs are not the most user friendly things to give you any hint on
where the problem is.

I can advise you to do it in two steps (XML + XSL -> XSL-FO and XSL-FO
-> PDF) to debug your problem, at least untill you've solved your
problem. That way you can examine the XSL-FO file and can edit it if you
want.

When I run FOP directly or on the temp FO file, FOP finishes without
error and produces an empty pdf file (empty as in no content, the pdf
file is 403 bytes long), but GSview gives an error on opening it (sorry,
I don't use Adobe Acrobat Reader), presumably because the pdf file
doesn't contain data.

You might want to tell us exactly how you invoke FOP, so we can try tp
reproduce your problem, but like Andrew said, I guess nobody is willing
to wade through 400 lines of code.

generating extremely large PDF documents with FOP

by: Ruchi Dayal | last post by:

Hi, I am using XSL-FO/FOP to generate PDF documents from XSLT. The resultant PDF can run into thousands of pages and this is where the whole problem is. FOP cannot handle such large outputs. Our initial solution was to manually feed limited records to FOP so that it wouldn't "bomb out". However, this is getting messier as the number of records themselves, increase. Due to previous architectural decisions, it is also not possible to

Hi there, this is a Java-XML Question, so I am not sure whether this is the right place, haven't found anything better .... I try to convert a Java object to XML via SAX and let the FOP Transformer convert that via XSLT to valid XSL-FO. So I define a SAXReader which fires the SAX Events for the Java Object. This works fine and the Transformation to PDF is ok. However, I have one object which contains an XHTML String and the tags
