Bug in Cocoon rendering bigger XML files to PDF??
I just wrote a xsl:fo to render a XML file to PDF.
testing it with a smaller XML file works perfectly (result are about 30
pages).
Then I replaced the small test XML with the regular xml file (about
2MB), Cocoon starts rendering, shows up to nearly 300 pages, NO error,
seems to finish, but then starts again from the beginning, from page
1... 300 again and again...
this should be a bug, no?

Thank you very mutch for your suggestions!!
But I think I'm not so skilled in java programming to be able to find the
bug!
Thank's again

If you want, you can try and find this bug. It should not be too hard -
if it is well reproducible.

Re: Transforming Big XML Files

It seems that using your suggestions, it works ...
But: why I can not use both Xalan and Saxon?
It is a bug ... or what?

But for the debug purposes, can you try running cocoon with only one
xslt processor, saxon, to see what result will you get?
Also, try adding to TOMCAT_OPTIONS:
-Djavax.xml.transform.TransformerFactory=com.icl.saxon.TransformerFactor

So, I like to use both:
I defined a component
"<component ... "
with:
<parameter name="transformer-factory"
value="com.icl.saxon.TransformerFactoryImpl"/>
." that uses Saxon in cocoon.xconf
and i defined another transformer (xslt-saxon) that calls this component
with:
"<xslt-processor-role>org.apache.cocoon.components.xslt.XSLTProcessor/Saxon</xslt-processor-role>"
In WEB-INF/lib there is saxon652.jar
Here are the coplete extracts of my cocoon.xconf and sitemap.xmap:
# cocoon.xconf
<component
role="org.apache.cocoon.components.xslt.XSLTProcessor/Saxon"
class="org.apache.cocoon.components.xslt.XSLTProcessorImpl"
logger="core.xslt-processor">
<parameter name="use-store" value="true"/>
<parameter name="incremental-processing" value="false"/>
<parameter name="transformer-factory"
value="com.icl.saxon.TransformerFactoryImpl"/>
</component>
# sitemap.xmap
<map:transformer name="xslt-saxon" pool-grow="2" pool-max="32" pool-min="8"
src="org.apache.cocoon.transformation.TraxTransformer">
<use-request-parameters>false</use-request-parameters>

This line look strange to me: why org.apache.xalan involved when you use
saxon?
Why don't you try without xalan in the classpath?

(I failed once to transform 100Mb file using command line tool, instant
saxon).

Transforming Big XML Files
Posted by Alessandro Marcellini <am...@tiscalinet.it>.
Hi all,
I've a problem transforming big xml Files with Xalan or Saxon.
I'm using Cocoon2.0.3 with tomcat3.3a on a Red Hat 7.2.
So, using Xalan, C2 throws an exception (No more DTM available .... Known
problem of Xalan)
using Saxon C2 throws this strange exception:
Original exception : java.lang.ClassCastException: com.icl.saxon.Controller

Solution: Lack of Memory
Posted by Alexander Schatten <al...@gmx.net>.
Thanks to a hint I received, I detected, that it was a memory problem.
If anybody should run into similar problems, add the following line to
tomcat, and restart tomcat:
set TOMCAT_OPTS=-Xms128M -Xmx256M
this increases the initial and the maximum java heap size to 128MB (256MB),
off course one can modify these settings.
Thanx
Alex

Re: Bug in Cocoon rendering bigger XML files to PDF??
Posted by SoftLiban ITANI Mohamed <mo...@softsolutions.fr>.
Hi,
Were you able to solve ur problem??
I'm going through the same problem, no matter what is the size of my XML.
I'm using cocoon with tomcat, cocoon seems to transform my XML 3 times if
adobe acrobat reader is not loaded and 2 times if it is???
Any idea, would be very useful.
Thanks in advance.
Itani
