What is wrong with my xsl-fo code

Question

I am trying to generate a pdf using apache-fop from the following command.

C:\fop-1.0-bin\fop-1.0>fop -xml sample1.xml -xsl xsl-fo.xsl -pdf sample2.pdf

My xml looks like this

<?xml version="1.0" encoding="iso-8859-1"?>
<service>
    <serviceId>11111</serviceId>
    <openDate>2012-02-16</openDate>
    <closeDate>2012-02-16</closeDate>
    <description>INSPECT MACHINE</description>
    <repairCost>$266.76</repairCost>
</service>

My xsl-fo xslt file looks like this

It's important to get the template match as and the for each as . also the xml file needs to have a root called services. I have tried this myself and it generates a pdf — , Dec 03 '12 at 23:42
I have copied the code you have put in the ans, checked the tags and tried, it failed — user525146, Dec 04 '12 at 01:53
Did you use the same xml? matches the root of the xml. loops over each service element. I've tried it a few times now and it generates a pdf each time, though I have noticed that the column names and the column values don't quite match up. You need to add a value for the order status columm — , Dec 04 '12 at 02:48
Thank you very much, I deleted the old files and created new ones then it worked but gave some warnings `Dec 3, 2012 8:43:40 PM org.apache.fop.events.LoggingEventListener processEvent WARNING: The following feature isn't implemented by Apache FOP, yet: table-layou t="auto" (on fo:table) (No context info available) Dec 3, 2012 8:43:41 PM org.apache.fop.events.LoggingEventListener processEvent WARNING: Font "Symbol,normal,700" not found.

Could it be as simple as a problem with case? Your sample XML uses <service> as the root tag but you have <xsl:template match="Service"> (capital S).

FOP doesn't support the automatic table layout and instead uses the fixed table layout

The auto layout is not supported by the FOP , as the page has a static width [A4, A3...] the auto mode is supported only in html rendring as the size of the page could change (depending on the resolution, resizing the window...) see :

http://mail-archives.apache.org/mod_mbox/xmlgraphics-fop-dev/200510.mbox/%3C20051005124250.8A19A21E@ajax.apache.org%3E

http://wiki.apache.org/xmlgraphics-fop/Troubleshooting/CommonLogMessage

Note : To avoid the warning you should specifie table-layout="fixed" , and use width="100%" and the "*" when defining columns widht
