Try adding this to your global.properties and then restart your alfresco service.


content.transformer.OpenOffice.extensions.docx.pdf.maxSourceSizeKBytes=10240
‍‍‍

That may or may not work. Its worth a try.

Unfortunately that didn't work.

Identical results to what I always had. I should also note that the thumbnail previews work, just not the full document.

Any other ideas?

Is this a vanilla install?

Might look at this and see what modules are installed.

what happens if you use the commandline to convert a doc to pdf? To do that

Put soffice.bin on your PATH


export PATH=/opt/alfresco/libreoffice/program:$PATH

‍‍‍‍

then upload a document in your home and do


soffice.bin –headless –convert-to pdf test.doc

Yes this is a pretty vanilla install, the only thing that I changed that's different from the "Easy" install method is I used "Advanced" and left out the Database and Sharepoint Plugin. I set up the database on a different server and it seems to be working fine that way.

When I ran http://mydomain.com:8080/share/service/modules/deploy I see that I have Alfresco Portlet Extension on the left site as an available module. Nothing is listed under modules deployed.

This is a very good idea for troubleshooting. I downloaded a doc into the directory, I named it test.doc.

Then:

<blockcode>
[root@web home]# export PATH=/opt/alfresco/libreoffice/program:$PATH
[root@web home]# ls
lost+found test.doc
[root@web home]# soffice.bin –headless –convert-to pdf test.doc
/opt/alfresco/libreoffice/program/.soffice.bin: error while loading shared libraries: libcups.so.2: cannot open shared object file: No such file or directory
</blockcode>

Any idea what this means? Out of curiosity I did a yum install libcups.so.2 but that didn't fix it. I did a reboot after the install was complete.

i think you are missing some libraries needed for soffice, try to install them

It worked! but…
When I log into Share I still receive <strong>"This document can't be previewed. Click here to download it."</strong>

I also still see this in my log when I start the server:

Any ideas on how I can test the connection between Share and OpenOffice?

I really appreciate the replies!

This might be worth a try…Download these add-ons.
http://addons.alfresco.com/addons/media-viewers
http://addons.alfresco.com/addons/wiki-rich-content

Place the jar files in /install/alfresco/tomcat/shared/lib

Restart your alfresco service.

Now go to http://localhost/share/service/modules/deploy

Here you will see modules that you can deploy. It will give you options for different viewers. I've personally deployed all EXCEPT the following.

PdfJs Viewer
MP3Player Viewer
MP3Player Configuration
FLVPlayer Viewer
Embed Viewer
WebODF Viewer
PdfJs Configuration
Prettify Viewer

This might help.

these modules rely on the transformation system to work for previews of office files, so that won't help him.

Post again a stacktrace you get in the log when a file needs to be transformed.

Have you tried using a new document?

Are you using Firefox 28 and was the document you are looking added using "upload new version"?

eswbitto — Fri, 04 Apr 2014 16:06:37 GMT

@hgindl I suggested this because I actually got the same errors. On 4.2.c CV. Which fixed the issue.

Re: Alfresco 4.2f - This Document Can't Be Previewed.

sicknick — Fri, 04 Apr 2014 18:35:26 GMT

I'll try this out if I can't get the out of the box transformation to work.

Re: Alfresco 4.2f - This Document Can't Be Previewed.

sicknick — Fri, 04 Apr 2014 18:59:12 GMT

Oh my… it's working now, I think a second reboot got it working after I installed those additional dependencies @hgindl suggested.

Funny thing is, I still got the same errors when I open a preview:

<blockcode>

</blockcode>

and the same WARN:

<blockcode>WARN [org.alfresco.util.OpenOfficeConnectionTester] An initial OpenOffice connection could not be established.
</blockcode>

and some additional new ones:
<blockcode>
WARN [org.alfresco.util.OpenOfficeConnectionTester] Error trying to query Open Office version information. OpenOffice.org's ConfigurationRegistry not implemented in this version of OOo. This should not affect the operation of OOo.
INFO [org.alfresco.util.OpenOfficeConnectionTester] The OpenOffice connection was re-established.
</blockcode>

@hgindl that was a great troubleshooting idea to isolate the converter and try and run it for errors, those errors basically cleared things up.

I would like to thank everyone here that helped solve this problem! Hopefully this thread can help others that run into this problem.

Good to hear.

This error messages are now neglegable in community edition. You are not using jodconverter so that messages are normal. And regarding the message of the openofficeconnectiontester that is because libreoffice doesn't seem to present a version number and maybe openoffice did, totally normal.
