README FILE FOR THE SUN XSLT COMPILER
Preview Version 6
April, 2001
=======================================================================

=======================================================================
The Sun XSLT Compiler (XSLTC) is a Java-based tool for compiling XSL
stylesheets into extremely lightweight and portable Java byte code.
The Sun XSLTC Java Runtime environment can then process XML files
against these compiled stylesheets (Translets) to generate any manner
of output per the style-sheet instructions.
This preview version of the XSLT Compiler can be run on any
platform -- including UNIX, Windows, NT, Mac -- that supports
Java2 or later. The Translets (compiled stylesheets) can be run on any
Java platform including a Palm Pilot with J2ME CLDC
(Java 2 Micro Edition, Connected Limited Device Configuration).
While the compiler itself requires Java2,translets are designed to run
anywhere Java is available.
Almost all functions of the XLST 1.0 language are implemented;
more than enough to show you how this new approach to XSLT works
and its advantages! Using the samples provided, you will be able
to see for yourself. Also, demos for the Palm Pilot, Applets, and
Servlets are provided.
-----------------------------------------------------------------------
ATTRIBUTIONS
-----------------------------------------------------------------------
The XSLT Compiler program uses the CUP Parser Generator
for Java, Copyright 1996-1999 by Scott Hudson, Frank Flannery,
C. Scott Ananian. For more details, please see:
http://www.cs.princeton.edu/~appel/modern/java/CUP/
The XSLT Compiler program also uses a modified version of the
Byte Code Engineering Library (BCEL), formerly known as
(JavaClass API), Copyright 2000 Markus Dahm.
** Please note that this additional package, BCEL, is
** needed in order to generate the class files from the compiler.
** Without the BCEL package, this preview version of the
** compiler WILL NOT WORK. BCEL is freely available for
** download as described below.
-----------------------------------------------------------------------
REQUIRED PACKAGE
-----------------------------------------------------------------------
BCEL (formerly JavaClass) by Markus Dahm has been
used to automatically create class files from the XSLT compiler output.
You must obtain the BCEL.jar file and install it before using the
XSLT compiler.
The simplest way to download the BCEL.jar file from
http://bcel.sourceforge.net/downloads.html
is to use the "JAR file (without docs)" link.
You may want to obtain the precompiled class files and documentation.
To download them to a Unix system:
1) Choose the "latest version (Precompiled + docs)"
Gzipped Tar-File or ZIP-File link.
2) Unpack and expand the downloaded BCEL files in your
download directory (e.g., /usr/local).
3) Change directory to BCEL.
4) Create the jar file BCEL.jar.
From within the BCEL directory, you can either use the
included GNUmakefile or create the jar yourself.
To use the GNUmakefile, type the command 'make jar'.
To create the jar yourself, type the command:
jar cvf BCEL.jar `find de gnu -name \*.class` listclass.class
To download the precompiled class files and documentation
to a Windows system:
1) Choose the "latest version (Precompiled + docs)"
ZIP-File link.
2) Unzip the downloaded BCEL files in your
download directory.
3) Change directory to BCEL and from a DOS command line,
type the command:
jar -cvf BCEL.jar de\fub\bytecode\classfile\*.class
gnu\regexp\*.class listclass.class
To complete the BCEL setup:
1) Install XSLTC, as described in the section below,
"HOW TO INSTALL XSLTC AND RUN THE SAMPLES."
2) Copy the BCEL.jar file into the "lib" directory
under your "xsltc" directory.
You are now set to run the XSLT compiler.
------------------------------------------------------------
ADDITIONS FROM VERSION 5 (of the PREVIEW COMPILER)
------------------------------------------------------------
Support for
- Simplified Stylesheets
- id() and key() in match patterns
------------------------------------------------------------
XSLT 1.0 Features Not Suported in PREVIEW VERSION 6
------------------------------------------------------------
The following XSLT 1.0 features are not yet supported:
* Nonstatic external Java methods.
You may call static Java functions
using a namespace prefix matching the class name that is
associated with the following URL:
http://www.sun.com/xsltc/java/YourJavaClass
* Namespace axis

------------------------------------------------------------
HOW TO INSTALL XSLTC AND RUN THE SAMPLES
------------------------------------------------------------
1. Unzip the files in a directory of your choice, for example
from the user directory '/home/user1', the distribution
zip file can be unzipped using the jar command as:
jar xvf xsltc-1_0-alpha5-bin.zip
The subdirectory 'xslt' will be created in '/home/user1'.
2. Set the XSLT environment variable to point to your installation
directory. Set your PATH environment variable to include
the bin directory of XSLT.
For example, in the bash shell:
export XSLT=/home/user1/xslt
export PATH=$XSLT/bin:$PATH
3. Compile the stylesheet to produce a Java class file.
For example, on the Unix platform, to compile the play1.xsl
stylesheet for the play.xml document:
cd /home/user1/xsltc/samples
xsltc play1.xsl
The compiled stylesheet will be in the main Java class file
'play1.class'
NOTE: The 'xlstc' shell script adds the required jars to your CLASSPATH
For example, on the Windows platform, to compile the play1.xsl
stylesheet for the play.xml document:
set classpath=c:\xsltc\samples;c:\xsltc\lib\xsltc.jar;
c:\xsltc\lib\xsltcrt.jar;c:\xsltc\lib\xml.jar;
c:\xsltc\lib\BCEL.jar;.
cd c:\xsltc\samples
java com.sun.xslt.compiler.XSLTC play1.xsl
4. Use the compiled Java class file (play1.class) to transform
the example XML document.
For example, on the Unix platform:
xslt play.xml play1
For example, on the Windows platform:
java com.sun.xslt.runtime.DefaultRun play.xml play1
The result is sent to standard output.
NOTE: When running the compiled stylesheet, you
just specify the name of its Java class, not its
file name (e.g., play1, not play1.class).
You do not include the ".class" extension, nor
the path to the class. The class is found by means
of the Java CLASSPATH variable. If you run
the translet from a directory other
than the directory in which the compiled
stylesheet class is located, you need to add
that directory to your Java CLASSPATH. Also, you
need to remove directories from your CLASSPATH
for prior installations of XSLTC and any references
to Sun's project X parser (com.sun.xml.tree)
installed from some other XML application/tool.
NOTE: The javadocToHtml sample calls external Java methods
from the JavadocFormatter class. Before compiling the
javadocToHtml.xsl stylesheet, compile the
JavadocFormatter class using 'javac'.
