Question

I have the following task:

@task(track_started = True)
def run_transcode_server():
    commands = ('java', '-cp', settings.TRANSCODE_CLASSPATH, settings.TRANSCODE_JAVA_CLASS)
    subprocess.call(commands)

Making the call to subprocess.call directly in the django shell works just fine. However, when celery tries to run that task, it causes this error: WindowsError: [Error 5] Access is denied.

I am running everything under the same user (this is my development environment).

What is causing this? Why can’t celery execute subprocesses?

Did you try writing the full path to the Java executable?
