[docbook-apps] Saxon and Catalog Resolver

[John Himpel <jwhimpel at tseinc dot com>]

Hi,

I am struggling with a tools problem.

I have a minimal .xml document marked up and validated.

I have a small customization layer for my stylesheets.

I have several chained catalog.xml files.

The contents of ./xml/catalog.xml follows:

<?xml version='1.0'?>
<!-- $XFree86: xml-work/xml/catalog.xml,v 1.3 2003/06/25 21:49:13
jwhimpel Exp $ -->
<!DOCTYPE catalog 
  PUBLIC '-//OASIS//DTD Entity Resolution XML Catalog V1.0//EN'
        
'http://www.oasis-open.org/committees/entity/release/1.0/catalog.dtd'
>

<catalog xmlns='urn:oasis:names:tc:entity:xmlns:xml:catalog'>
  <public
    publicId='-//OASIS//DTD DocBook XML V4.1.2//EN'
    uri='./docbook/oasis-open/xml-dtd-4.2/docbookx.dtd' />
  <system
    systemId='http://www.oasis-open/docbook/xml/4.1.2/docbookx.dtd'
    uri='./docbook/oasis-open/xml-dtd-4.2/docboox.dtd' />
  <nextCatalog catalog='./docbook/oasis-open/xml-dtd-4.2/catalog.xml' />
  <nextCatalog catalog='./docbook/oasis-open/docbook-xsl/catalog.xml' />
  <nextCatalog catalog='./docbook/oasis-open/MathML/catalog.xml' />
  <nextCatalog catalog='./docbook/XFree86/catalog.xml' />
  <nextCatalog catalog='./docbook/w3/MathML/catalog.xml' />
</catalog>


When I run xsltproc using fo/docbook.xsl as the stylesheet and setting
XML_CATALOG_FILES to ./xml/catalog.xml and no internet access, xsltproc
runs
fine.

When I run the following saxon.sh file with internet access it runs
fine.

SAXON_BIN=/usr/local/Saxon
SAXON_EXTENSIONS_BIN=/home/??????/XFree86/Devel/xml/docbook/oasis-open/docbook-xsl/extensions
XALAN_BIN=/usr/local/Xalan/xalan-j_2_5_1/bin
CLASSPATH=${CLASSPATH}:\
${SAXON_BIN}/saxon.jar:\
${SAXON_EXTENSIONS_BIN}/saxon651.jar:\
${XALAN_BIN}/xercesImpl.jar:\
./xml

export CLASSPATH

       -y org.apache.xml.resolver.tools.ResolvingXMLReader \
       -r org.apache.xml.resolver.tools.CatalogResolver \
       -u \
       ${1}.xml \
       xml/docbook/oasis-open/docbook-xsl/fo/docbook.xsl \
       use.extensions=1


My CatalogManager.properties files resides in ./xml and is as follows:

catalogs=catalog.xml
relative-catalogs=false
static-catalog=yes
catalog-class-name=org.apache.xml.resolver.Resolver
verbosity=4

When I run the above saxon.sh file without internet access, it get the
following stack trace.

java.lang.ArrayIndexOutOfBoundsException: 3

Possible causes that occur to me are are:
1) An incorrect CatalogManager.properties file
2) A problem in saxon.sh
3) A problem in one of my catalog.xml files that is tolerated by
xsltproc and is
fatal to Norm's resolver classes.
4) A bug in Norm's resolver classes (highly unlikely).

Also, please be aware that I have placed resolver-1.0.jar in
/usr/java/j2sdk1.4.1_02/jre/lib/endorsed.

I know many others have gotten this work, so it must be something really
dumb that I have done.

If I had a clue as to which entity it is trying to resolve, it would be
useful.

Any guidance would be greatly appreciated.

John
