I am trying to convert doc to pdf/a using jodconverter and libreoffice. Default configuration allows to generate only 1.4 or 1.5 format. The only official option I have found is to use a proprietary "Document transformation engine". I don't like it because you need a windows server and ms office.
LibreOffice supports generation PDF/A via "SelectPdfVersion" property in a user configuration file (registrymodifications.xcu)
The configuration "registrymodifications.xcu" is created dynamically when a transformation is called by jodconverter (hope so). I need to add the "SelectPdfVersion" line to it somehow.
Libreoffice runs as a service in my environment (docker).
/opt/libreoffice6.1/program/soffice.bin -accept=socket,host=127.0.0.1,port=8100;urp; -env:UserInstallation=file:///tmp/.jodconverter_socket_host-127.0.0.1_port-8100 -headless -nocrashreport -nodefault -nofirststartwizard -nolockcheck -nologo -norestore
I tried to rewrite the jodconverter library in (repository docker) /usr/local/tomcat/webapps/alfresco/WEB-INF/lib/alfresco-jodconverter-core-184.108.40.206.jar to put this config dynamically to (libreoffice docker) /tmp/.jodconverter_socket_host-127.0.0.1_port-8100/user/registrymodifications.xcu but it doesn't seem to have any effect.
Also try patch and OOoDirect approach from link below, but I cannot find the relevant configuration files (openoffice-document-formats.xml).
Is there any way to set alfresco to generate PDF / A?
