http://wiki.openlaszlo.org/OpenLaszlo_Developer_Hints .lzs: Javascript with OpenLaszlo compiler extensions, for example, to include files see #include "compiler/Library.lzs" in LaszloLibrary.lzs. Used for portions of the LFC that aren't runtime specific, for example, everything not in kernel/*.
The corresponding LaszloScript file is not generated, but can be found here: http://svn.openlaszlo.org/openlaszlo/tags/4.9.0/WEB-INF/lps/lfc/core/LzEventable.lzs The error seems to report that the "class" token is not expected in this position. Looks like something is broken in your setup. I've only built the server on OS X and Linux (Redhat and Ubuntu), and never ran into those problems.
