I try to install this jars (https://maven.alfresco.com/nexus/content/groups/public/com/artofsolving/jodconverter-core/) in the share/lib tomcat directory. The error is different but the problem persist.
I do not understand if the community edition can use this subsystem. Can you explain me?

I open a JIRA: https://issues.alfresco.com/jira/browse/ALF-20108

Hello Marcello,

Your problem with your online preview with Office files is because Alfresco don't have access to a LibreOffice application (transformation service) so it cannot convert it to PDF and PDF2SWF could do the rest of the preview (transform pdf to sfw).

I can see the following lines in your alfresco-global.properties
   <strong>jodconverter.officeHome=/usr/lib/libreoffice
   jodconverter.portNumbers=8101,8102,8103
   jodconverter.enabled=true</strong>

Did you change this configuration manually? Was enabled before <strong>ooo.enabled</strong>?

As I can see your Alfresco server could not make LibreOffice work as service (JodConverter). I've tried a couple times and it does not work just changing from one subsystem (ooo) to the other (jodconverter). Checking a solution for that I've found this link in <a href="http://docs.alfresco.com/community/index.jsp?topic=%2Fcom.alfresco.community.doc%2Fconcepts%2Finstall-lolibfiles.html">docs.alfresco.com</a>. It seems to be a validation with Alfresco full installer, it check if some libraries are present in the installation server to allow JodConverter works normally, if those libraries are not present installer disables JodConverter and enable direct transformation (ooo.enabled=true).

Try installing this libraries to make LibreOffice works and you will have no problems with preview.

Another option if you are in a hurry is install OpenOffice 3.3 and configure Alfresco transformation service to use this OpenOffice.

Best regards,
Diego.

PD: I can see in jodconverter port numbers 8101,8102,8103, I have seen always just one port here, it could be causing some troubles with transformation services too. I could recommend to you fix this first and try with the rest. BYE.

(SOLVED) my problem was a mis-configuration of image-magick in /opt/alfresco/tomcat/webapps/alfresco/WEB-INF/classes/alfresco/subsystems/thirdparty/default/imagemagick-transform.properties
(I don't know the reason because of with 4.2.c worked)

I put this
# External executable locations
img.root=/usr
img.dyn=${img.root}/lib
img.exe=${img.root}/local/bin/convert
#img.coders=${img.root}/modules/coders
#img.config=${img.root}/config
img.gslib=${img.root}/share/ghostscript/9.05/lib

in that file and thumb works as it should.

thanks!

PS.
I've disable jodconverter, but at start I have some errors like
2013-10-09 08:25:31,235 ERROR [content.transform.TransformerConfigDynamicTransformers] [http-bio-8080-exec-7] Cannot create dynamic transformer transformer.complex.JodConverter.Pdf2swf as sub transformers could not be found or created ("JodConverter.2Pdf|pdf|Pdf2swf").

I dont know why….

Not sure if it's the same problem but I installed a fresh Alfresco 4.2.e and didn't see previews.

Turned out I had to install Libxinerama

In Ubuntu 12.04.3 LTS -> "apt-get install libxinerama-dev libxft-dev libxi-dev" as root
