No preview for office documents (random behavior)

Hi thereI'm an Alfresco newbie, so please excuse me for any stupid question. I swear I searched extensively before posting !I installed several Alfresco versions in the past weeks, including community 4.2.c, d and e, and enterprise 4.1.6 [edit] now running 4.2.0 enterprise [/edit]. Each time I did i

I'm thinking it has to do with your file size and file type….Issues that I have come up with this specifically had to do with pdf files.


content.transformer.complex.OpenOffice.Pdf2swf.extensions.doc.swf.maxSourceSizeKBytes=10240
content.transformer.complex.OpenOffice.Pdf2swf.extensions.docx.swf.maxSourceSizeKBytes=10240
content.transformer.OpenOffice.extensions.docx.pdf.maxSourceSizeKBytes=10240
‍‍‍‍‍

put that in your alfresco-global.properties and restart the service. See if that helps….The other thing that would help is reviewing the logs when you try and navigate to the document. That will give you a clue into how you need to proceed.

Thanks for your input !

I already tried this a couple weeks ago, it didn't change anything. Among the file that can't be previewed are very small, almost empty word or excel files, even .txt files with just a few signs. The size doesn't seem to be the issue, since either everything works, including rather big PDF files, or nothing works, including text files under 1kB…

I installed 4.2.0 enterprise today, on a fresh Debian Wheezy as always, and the "cannot be previewed" message is back. I just installed in easy mode, with all default settings, rebooted, created a site, uploaded various files (txt, word, pdf, xls, recent format and old ones, big and small files). None can be previewed.

If anyone as a clue, I'd be glad to know ! I join the log file.

edit :
I just installed from scratch another time. It still doesn't work. I noticed I can add files via drag and drop, but clicking "import to warehouse" then "add files" gives me an error. The upload doesn't even start. The log file is unchanged since the end of the installation.

edit 2 :
adding files through "import to warehouse" works in Internet Explorer, still no preview. I always used Firefox before, even when previews were working fine.

From your log, although it says "for informational purposes only", it looks to me like OpenOffice (LibreOffice as it now is) is not running. Can't tell you why but if you don't have OpenOffice running you will not get previews for most documents.

I found something that might be interesting regarding Libreoffice.

The alfresco.sh file mentions "LIBREOFFICE_SCRIPT=$INSTALLDIR/libreoffice/scripts/ctl.sh"

"ctl.sh" doesn't exist. The only file in that folder is "libreoffice_ctl.sh".

I never touched that file. How can it be wrong ? It seems to work for everybody else. I'm missing something. I made a copy named "ctl.sh", restarting Alfresco…

edit : nothing changed after restart the alfresco service or rebooting.

edit : Exploring some issues reported on Jira. Installing libcups2 as mentioned didn't change a thing. actually, none of the libraries required by LibreOffice were installed (libice6 libsm6 libxt6 libxrender1 libfontconfig1 libcups2). I installed them all, nothing changed.

edit (again) : things seem less random with 4.2.0 enterprise, since previews never worked on 3 different installations.
