                           |  How to build Fop |
                           * ================= *

           Adaption from the Cocoon build.xml written by Stefano Mazzocchi
                by Giacomo Pati with some addition by Fotis Jannidis 


Introduction
============

FOP is the world's first print formatter driven by XSL formatting objects. It 
is a Java 1.1 application that reads a formatting object tree and then turns 
it into a PDF document. The formatting object tree, can be in the form of an 
XML document (output by an XSLT engine like XT or Xalan) or can be passed in 
memory as a DOM Document or (in the case of XT) SAX events.
    
FOP is part of Apache's XML project. The homepage of FOP is 
http:/xml.apache.org/fop 

HTML-Documentation can be found in the subdirectory ./docs. 


Installing the build tools
==========================

The Fop build system is based on Jakarta Ant, which is a Java building tool
originally developed for the Jakarta Tomcat project but now used in many other
Apache projects and extended by many developers.

Ant is a little but very handy tool that uses a build file written in XML
(this file) as building instructions. For more information refer to
"http://jakarta.apache.org/ant/".

To make things easier for you, the Fop distribution contains a
precompiled version of Ant and the build scripts take care of all the
classpath issues except the following:

You need to have xerces.jar, xalan.jar and bsf.jar (comes with xalan) in 
your classpath. You can get those from http://xml.apache.org/xerces and 
http://xml.apache.org/xalan respectively.

Additionaly you have to make sure, that the "JAVA_HOME" environment
property should be set to match the JVM you want to use. That's it.


Building instructions
=====================

First, make sure your current working directory is where this very file is 
located. Then type

  ./build.sh (unix)
  .\build.bat (win32)

if everything is right and all the required packages are visible, this action
will generate a file called "fop.jar" in the "./build" directory. Note, that
if you do further development, compilation time is reduced since Ant is able
to detect which files have changed an to recompile them at need.

If something went wrong, go to the FAQ section below.

Also, you'll note that reusing a single JVM instance for each task, increases
tremendously the performance of the whole build system, compared to other
tools (i.e. make or shell scripts) where a new JVM is started for each task.



Build targets
=============

The build system is not only responsible of compiling Fop into a jar file,
but is also responsible for creating the HTML documentation, javadocs,
distributions and web site. In fact, the file you have here is _exactly_ what
is used by fop maintainers to take care of everything in the Fop
project, no less and no more. (only partially implemented)

These are the meaningful targets for this build file:

 - package [default] -> creates ./build/fop.jar
 - usage -> shows a help screen
 - codegen -> generates needed java sources from xml resources
 - docs -> generates the HTML documentation in ./build/docs
 - javadocs -> generates the API documentation in ./build/javadocs
 - dist -> generates the Fop distribution
 - clean -> restores the distribution to its original and clean state 
            (excepting dist files)
 - distclean -> restores the distribution to its original and clean state
 - site -> generates the web site in ../xml-site/targets/fop (not yet impl.)

====================================== FAQ =====================================

1) Why some of the classes present in the original jar are not built anymore?

The fop build system is very flexible: if a module requires a package that
is not present in the classpath at build time, the module is skipped but
the built process is not stopped.

Here is a list of such modules and what you have to download to build them:

 org.apache.fop.apps.XTCommandLine ===>
       James Clark's XT (http://www.jclark.com/)

2) I see a lot of warnings starting like this: "Warning: file modified in the future:"
Sometimes ant gives out this warnings, but the build is finished without any problems
