You need to look in the Apache error log files to find the actual
details of the error. This may be a Python traceback, or an error from
Apache or mod_wsgi. Post the whole section generated at the time of
the request, please don't post just a bit that you think is relevant
as you may not include important details.

At a guess though, I would say it is because you need:

sys.path.append('/var/www')

instead of:

sys.path.append('/var/www/samplewsgi')

Although am at a loss as you why you have:

sys.path.append('/var/www/samplewsgi')
from samplewsgi import app as application

in the first place.

Have you tried with the hello world program at:
