Java mapping additional file not found

Hi folks,

I have a java mapping where I am creating an xlsx file from xml content. The file is based on xlsx template that I have placed in the root of the project folder. When I test the mapping from my local eclipse, the xlsx template is found and the output xlsx generated as intended.

However when I create the imported archive from the jar file (which contains the template) and execute the java mapping, the PI log says that it cannot find the template file.

Do you have any idea what am I missing?
