In Eclipse create a new project "de.vogella.docbook.first", select File -> New -> Project and select from the proposed list General -> Projects.
Create the following folder structure:
output: Contains the result of the conversion
docbook-xml-4.5: Contains the DTD definition for DocBook
docbook-xsl: Contains the XSL stylesheets to convert to the other output formats.
lib: Will contains your libraries (for pdf creation)
documents: Contains your DocBook files
Place the DocBook DTD and the XSLT stylesheets in the directories from above.
After this your DocBook development environment is ready to be used.
Create the folder "/lib/xalan" and copy the xalan jars into this folder. The result should look like the following.

In your folder "documents" create a following file "book.xml":
<?xml version="1.0" encoding="UTF-8" standalone="no"?> <!DOCTYPE article PUBLIC "-//OASIS//DTD DocBook XML V4.5//EN" "../docbook-xml-4.5/docbookx.dtd"> <article> <articleinfo> <title>DocBook Intro</title> <author> <firstname>Lars</firstname> <surname>Vogel</surname> </author> </articleinfo> <sect1 label="1.0"> <title>An introduction to DocBook</title> <para> This is text. </para> </sect1> </article>
You have created your first DocBook document.
We will now create an Ant file. See Apache Ant Introduction to learn more about Ant.
Create the following file "build.xml" in your project directory.
<?xml version="1.0"?>
<!--

<copy todir="${doc.dir}">
<fileset dir="lib">
<include name="style.css" />
</fileset>
</copy>
</target>
</project>
Run the build.xml file (right mouse click, run as -> Ant Build). Then check the output directory. You should find a directory Example, with the file book.html.
Congratulations!
