Open MS Word docx document does not open on Tomcat 9

Hi

The following code opens a Word docx file. It runs perfectly inside my IntelliJ IDE (IntelliJ IDEA 2022.2.3 (Ultimate Ed.)) where I run '.SmartTomcat' version 9. 

However when I package the application to a war file (using Maven) and deploy it to my local Tomcat 9 service it does not open the file and there are no visible errors in the logfiles.

What could be the reason for this behaviour and how could I tackle this problem? Any ideas or hints are welcome?

Kind regards

Riccardo

public class TestOpenWordDoc {
   public static void main(String[] args){
      try{
         if(Desktop.isDesktopSupported()) {
            System.out.println("Desktop supported");
            File docxFile = new File("C:\\test_data\\certificate_149.docx");
            Desktop.getDesktop().open(docxFile);
         } else {
            System.out.println("Desktop not supported");
         }
      }catch (Exception e){
         System.out.println("error opening worddoc " + e);
      }
   }
}
