Installation
The YAWL System (also referred to as the YAWL Environment) comprises a number of web servlets and
a java-based Editor desktop application. It requires a Servlet Container to host the servlets and a back-end
database system for process data storage and archiving. Individual YAWL components may be installed
manually (see Section 2.4), but there are also a number of automatic YAWL installation packages that install
all the required components and allow you to be up and running with YAWL quickly and easily:
•
YAWL4Study is available for Windows, Linux and Mac OSX platforms. This is the installer to choose
if YAWL is to be used within a single user environment (for example, to write a research paper based
on YAWL or to prepare your next workflow lecture). Furthermore, YAWL4Study is the right choice if
you intend to learn about or to experiment with YAWL. The resulting pre-configured installation has
the complete YAWL functionality and contains the same YAWL components as YAWL4Enterprise.
•
YAWL4Enterprise is an installer for Windows only. Third-party components like Apache Tomcat and
PostgreSQL are installed separately as services so that YAWL can be used as a long-running server for
production purposes. Furthermore, this installer allows for some configuration of the YAWL environment. For production purposes on a Windows platform this is the installer to choose. See Section 2.4
for instructions on how to install the enterprise version of YAWL for multi-user production environments on other operating platforms.
The complete YAWL environment is installed whichever installer is chosen. Further information on the
different installer types can be found on the YAWL project web-page on SourceForge1 .
Official and stable versions of the YAWL installation files are found on the YAWL project web-page on
sourceforge2 under Download, release package YAWL Complete.

Requirements
All installers, and YAWL itself, require the Java SE Runtime Environment (JRE), 1.6 or greater (java.sun.
com).
YAWL4Study for Linux requires installed xdg-utils (portland.freedesktop.org), which should be
supported by your desktop environment (GNOME and KDE do support xdg-utils), in order to visualise
YAWL Editor menu entries.
