This page has links to useful documentation. If you are unfamiliar with Open Laszlo, going through "Laszlo in 10 Minutes" is a good idea.

There are some excellent example applications, with source available, at http://www.openlaszlo.org/demos; I'd particularly recommend looking at LZPIX.
Download the 4.0.2 version of OL by going to http://www.openlaszlo.org/archive.
Installing OpenLaszlo
Unpack the software wherever you want to install it. Because it has its own embedded version of tomcat, there can be port conflicts if you already have tomcat running on your machine. To prevent any conflicts, edit <OL-Directory>/Server/tomcat-5.0.24/conf/server.xml.
** Change port from 8005 to 8006
<Server port="8006" shutdown="SHUTDOWN">
