Answer 1

I think there are several reasons listed on their homepage why conversion cannot work under linux:

[...] the LocalConverter can only be run if:

• The JVM is run on a MS Windows platform that ships with the Microsoft Scripting Host for VBS (this is true for all contemporary versions of MS Windows.
• MS Word is installed in version 2007 or higher. PDF conversion is only supported when the PDF plugin is installed. The plugin is included into MS Word from Word 2010 and higher.
• MS Word is not already running when the LocalConverter starts. This is in particularly true for MS Word instances that are run by another instance of LocalConverter. (As mentioned, be aware that this is also true for instances running on a different JVM or that are loaded by a different class loader.)
• MS Word is properly activated and configured for the user running the JVM. MS Word does therefore not require any configuration on program startup or any other wizard.
• When the JVM application which uses the LocalConverter is run as a service, note the information on using MS Word from the MS Windows service profile below.
