Converting docx to pdf via JODConverter and LibreOffice causes error

Question

I have 1000 .docx files that I want to convert to pdf so I have written a program to do this, but I can never get through all 1000 files before an error is thrown. I start a headless version of LibreOffice using soffice --headless --accept="socket,host=127.0.0.1,port=2002;urp;". I am using LibreOffice 4.2.0.4 and JODConverter 2.2.2. This is my conversion code (prior to this I just iterate all the .docx files in a directory):

try {
        File inputFile = new File(sourceFile);
        if (!inputFile.exists()) {
            return -1;
        }

        File outputFile = new File(destFile);
        OpenOfficeConnection connection = new SocketOpenOfficeConnection(host_Str, 
            Integer.parseInt(port_Str));
        connection.connect();
        DocumentConverter converter = new OpenOfficeDocumentConverter(connection);
        converter.convert(inputFile, outputFile);

        connection.disconnect();

        return 0;
    }

    catch (ConnectException e) {
        System.out.println("Openoffice listener exception!");
        return 1;
    }

I can always convert at least 50 files or so before an error is thrown; this is one of the errors I have had:

In every situation (so far), I have been able to retry the conversion on the docx file where the error occurred and the conversion has been successful.

I have looked at similar questions on this site but most them are for situations where an error is thrown the first time a conversion is attempted, whereas in my case there are always some successful conversions before a failure. I have also tried using OpenOffice with the same results. I have tried googling error messages but to no avail.

My question is why are these errors occurring, and what can I do to convert all 1000 docx files? Also I am aware of docx4j but I need to be able to convert .doc files as well which this does not support.

Answer 1

I'm working with PHP and using the python script to convert and I faced a problem similar to yours, I had errorCode 283 and SfxBaseModel::impl_store failed: 0x11b.

I have an Apache server that runs with apache user and a regular user that runs LibreOffice service, let's say theuser, theuser is on apache group in order to write on tmp folders of my app. When I convert to pdf I create a folder (let's call it thefolder) to store the converted file (using mkdir function on PHP) I saw that thefolder hasn't group write permission and I test with other location from terminal (with theuser user) and it works, on thefolder I have errorCode 283, what I did is use umask function in PHP to change the permission for the creation of thefolder.

Summary: Check permissions on folder in wich you'll put the resulting file
