[Python] The same command runs perfectly when executed directly on the Linux server, but it...

I have a Python script that uses pyhtml2pdf:


import os
import sys
from pyhtml2pdf import converter

def convert_html_to_pdf(html_path, pdf_path):
absolute_html_path = os.path.abspath(html_path)
converter.convert(f'file:///{absolute_html_path}', pdf_path, 60, False, 0, False)

if __name__ == "__main__":
if len(sys.argv) != 3:
print("Usage: python3 test.py <html_path> <pdf_path>")
else:
html_path = sys.argv[1]
pdf_path = sys.argv[2]
convert_html_to_pdf(html_path, pdf_path)


When I run the command directly on a Linux server:

DISPLAY=:99 python3 test.py 298.html 298.pdf


it executes perfectly, and 298.pdf is generated. However, when I try to run this command from within a Java program using:

String comds = "DISPLAY=:99 python3 test.py 298.html 298.pdf";
Runtime.getRuntime().exec(comds);


I encounter the error:
