Re: DOCBOOK-APPS: xsl-fo: title page customization and bug resolutionin xsltproc

[Damian Kohlfeld <damian at kohlfeld dot com>]

I had the same problem over the weekend.  This must be a problem with
xsltproc, I wrote a readme for the complete resolution process.  It entails
using the java Xerces-Xalan-FOP build environment, support seems to be
better in this environment and the performance isn't as desirable as
xsltproc, but I believe it is more supported and will eventually replace
xsltproc as time goes on (I opened a can of worms on that statement ;).  Do
the following (or move directly to line item 7 if you have
Xerces-Xalan-FOP).

To create build environment for DocBook Documents (Redhat Distro)
-------------------------------------------------
Date:    Feb 18, 2003.
Author:  Damian Kohlfeld

1) install j2sdk-1.4.x
 (j2sdk1.4.1_01 at time of this writing)

2) cd into /usr/java/j2sdk1.4.1_xx directory
 (/usr/java/j2sdk1.4.1_01 at time of this writing)

3) install jai-lib-linux for the JDK (not JRE environment)
    Note: This isn't documented anywhere!!! in the FOP install docs.  The rc
version of FOP no longer uses Jimi.
 (jai-1_1_2-beta-lib-linux-i586-jdk at time of this writing)

4) cd into opt and unzip xalan bundle and fop
 (xalan-j_2_4_1-bin.tar.gz and fop-0.20.5rc-bin.tar.gz at time of this
writing)

5) Update the CLASSPATH variable in $HOME/.bash_profile to include
directory to the tools.jar file which came with the j2sdk, where
$HOME is the path to your home directory.

i.e. (for j2sdk1.4.1_01 at time of this writing)
CLASSPATH=/usr/java/j2sdk1.4.1_01/lib/tools.jar

export CLASSPATH

6) Update your PATH variable in $HOME/.bash_profile to include the
path for the java executable, where $HOME is the path to your home
directory.

i.e. (for j2sdk1.4.1_01 at time of this writing)
PATH=$PATH:/usr/java/j2sdk1.4.1_01/bin

export PATH

7)  To create the custom stylesheet with the spec file, run this command:

java -Djava.endorsed.dirs=/opt/xalan-j_2_4_1/bin
org.apache.xalan.xslt.Process\
 -out fo/mytitlepages.xsl -in fo/titlepage.templates.xml\
 -xsl template/titlepage.xsl


---------------------------------------------------------------------

You are now ready to build DocBook documents using the build scripts.
