Problems with FOP and XML/XSL

[Ramon Maria Gallart <rg...@asistemas.net>]

    Hi all.
 
    I'm new to FOP, XML, XSL, FO and so on. I'm getting an error message
when i try to get a PDF from a XML and XSL source. The message i'm
getting is the following:
    [INFO]: FOP 0.20.3
    [INFO]: building formatting object tree
    [INFO]: Parsing of document complete, stopping renderer
    [ERROR]: java.lang.ArithmeticException: / by zero
 
    As you could see, the error is for a division by 0 which means that
when i'm going to see the *.pdf that FOP has created, it has no pages at
all.
 
    If it is useful, i put here the command i use to execute FOP:
 
        C:\fop-0.20.3>fop -xsl c:\java\plantillaInformeFO-2.xsl -xml
c:\java\informe3.xml -pdf c:\java\informe.pdf
  _____  

    I put also here the documents used to do the transformation:

Are you sure you produced this message with the code below?

Wrong namespace. The correct one is already declared above.
FOP barfs #1;

Shorthand property margin is not yet implemented. Use margin-top,
margin-left and so on.
FOP barfs #2, this time a warning only.

A flow has to be inside a page-sequence, this means...>         <fo:page-sequence master-reference="all">

... here.

After this is corrected your sample files produce a perfectly
usable PDF.
