Cannot convert XHTML to XML-FO using Xalan-J and xhtml2fso.xsl stylesheet

[John Brown <jo...@hotmail.com>]

First of all, I know nothing about Xalan.

The following article in the JavaWorld Forums:

http://www.javaworld.com/javaworld/jw-04-2006/jw-0410-html.html

explains how to convert HTML to PDF by using JTidy, Xalan and Apache FOP.
The steps are as follows:
1) HTML -> XHTML uing jtidy-04aug2000r7-dev
2) XHTML -> XML-FO using xalan-j 2.7.0
3) XML-FO -> PDF using Apache fop-0.20.5

My problem is that Xalan does not seem to be working.

I am using Windows XP, and I have these packages installed in
c:\downloads\utils\jtidy-04aug2000r7-dev
c:\downloads\utils\xalan-j_2_7_0
c:\downloads\utils\fop-0.20.5
(All binary distributions; I did not compile them myself)
Java 1.6 JRE (1.6.0_03) in C:\program files\java\jre1.6.0_03
Java 1.6 JDK (1.6.0_03) in C:\program files\java\jdk1.6.0_03

xhtml2fo.xsl is an XML stylesheet for converting the output of JTidy to
XML-FO. This stylesheet is supplied with the article.


Following the instructions in the article, I ran the following commands:
java -cp c:\downloads\utils\jtidy-04aug2000r7-dev\Tidy.jar -asxml \
  hello.html> temp.xml

java -cp \
  c:\downloads\utils\xalan-j_2_7_0\xalan.jar\
  ;c:\downloads\utils\xalan-j_2_7_0\xercesImpl.jar\
  ;c:\downloads\utils\xalan-j_2_7_0\xml-apis.jar\
  ;c:\downloads\utils\xalan-j_2_7_0\serializer.jar\
  org.apache.xalan.xslt.Process -TT -TG -TS -TTC -IN temp.xml\
  -XSL xhtml2fo.xsl -OUT temp.fo 
c:\downloads\utils\fop-0.20.5\fop.bat temp.fo hello.pdf

Of course, I did not really use the "\" character. Each command is on
one line, with no unnecessary white space.


JTidy produces the following XML file:




Hello World


Hello World!



This seems to be OK.

The console output of xalan is:

I do not understand any of this, but all those lines with line #-1,
column #-1 cannot be good. The resulting file is:




Hello World


Hello World!

This is obviously wrong.

The article supplied a file Html2Pdf.java, which is supposed to be the
equivalent of the sequence of commands. I compiled it, and it works.

What am I doing wrong?
