Configuring preview with LibreOffice

I'm having some trouble setting up the document preview and annotations tool with LibreOffice.

• First, the LibreOffice daemon never starts with nuxeo (Nuxeo documentation says : "If OpenOffice/LibreOffice is already installed on your server, Nuxeo applications come with a daemon that should automatically start it.") I can't find any documentation on how to configure the ooo-manager-config.xml file.

• Second, after starting the daemon "by hand", the preview function still does not work.

Thanks for your help,

Patrice

No Libreoffice daemon running :

$ ps -edf |grep office |grep -v grep
$ netstat -taupe |grep office
$

Not working preview after hand running office daemon :

$  /usr/lib64/libreoffice/program/soffice --headless --nologo --nofirststartwizard --accept="socket,host=localhost,port=2222;urp;StarOffice.Service"&
$ ps -edf |grep office |grep -v grep

Error message when clicking on the preview icon :

Preview can not be generated for this document.
``Blob path: default.

Our Nuxeo config for Office :

Nuxeo uses a JOD based converter, which uses the following code:

    try {
        officeManager = configuration.buildOfficeManager();
        officeManager.start();
        started = true;
        log.debug("Starting ooo manager.");
    } catch (Exception e) {
        Throwable t = unwrapException(e);
        log.warn("OpenOffice was not found, JOD Converter "
                + "won't be available: " + t.getMessage());
    }

It sets the started property to true, when there is no exception. The property is used later to check if OO is running. It means that the code above have to be done properly.

So, you should check:

1. if you have nuxeo-platform-convert-5.6.jar bundle in nxserver/bundles subdirectory,
2. if you have jodconverter-core-3.0-NX3.2.jar library in nxserver/lib subdirectory,
3. logs in the server.log file. The JOD records a lot informations.

You can also set the DEBUG logging level in log4j.xml file (the change requires restart).
