1.  Get the 4.0.2 version going to [http://www.openlaszlo.org/archive]. Choose the Servlet for 4.0.2.

2.  Can be installed via tomcat manager

3.  LPS_HOME must be set as an environment variable, so that the compiler can run. LPS_HOME should be set to the directory where the servlet was installed, e.g. /home/apache-5.5.23/webapps/openlaszlo-4.0.2-servlet

4.  For some reason, the compiler script (a file called lzc) is not executable when installed. It needs to be made executable by going into $LPS_HOME/WEB-INF/lps/server/bin and chmod 755 lzc.

5.  The call to the compiler comes from create_slideshow.jsp, which is checked in to the webapp dir of the ime. It requires that there be source .lzx files in a directory called downloadable_slideshow in the webapps directory. These files are copied in by the maven script when a full release is done, assuming the following switches are used:

{code

}
-Dincludeui=true -Duipath=<path-to-ui-source-trunk/branch>
{code}
6.  Here is a list of the files that should be in the folder downloadable_slideshow:

{code

}
downloadable_slideshow.lzx
classes/icon.lzx
classes/matrixview/matrixitem.lzx
classes/matrixview/slide.lzx
classes/matrixview/slide_dropspot.lzx
classes/proportionalimage.lzx
classes/thaliacolorpicker.lzx
data/context_data.lzx
includes/slideshow/ss_player.lzx
includes/slideshow_resources.lzx
resources/generic_thumbnails/*
resources/slideshow/slide_drop_spot.jpg
resources/slideshow/viewer/*
{code}
7.  Currently, create_slideshow.jsp writes to System.out, not the thalia.log. So, to check errors, look in tomcat/logs/catalina.out. Errors are likely to be one of the 3 things:

{code

}
lzc compiler was not executable, in which case you'll see a 'permission denied' errorLPS_HOME not setSome of the required .lzx source files are missing -- it will say in the error what source file is missing.
