Re: python code works in command line but not in django

Hi All,

I apologize for now being specific enough. The java script should read
files in "tmp/medusa" and use "Medusa.jar" as the referenced class to
run. The result of the script should be a png image using data from
files inside "tmp/medusa"

I tested the java command via terminal and it worked fine. The PNG
image was created correctly.

I tested the python package using python shell by importing
MedusaConnector and run the "MedusaConnector.create_image()", and the
PNG image was created properly as well.

Therefore, I imported the Medusa package into my views.py and try to
run it using django. This time, the PNG file was created, but with and
empty image unlike those 2 previous test cases.

Really have no idea what's going on here...
