FWIW, this really is a question for the jython-users mailing list - you are
more likely to have users who have experience with this specific package.
However, let's see what we can do:

So these are paths, not files. Specifically the result of
request.getContextPath() will be a unicode object; when you concat with a
str ('/Energy+V7_2_0.idd'), it remains unicode.

were trying to treat the above unicode path as it's an already open file.
Do one more step, by opening the file for that path:
with open(request.getContextPath() + '/Energy+V7_2_0.idd') as iddfile:
# use this file in your code
It's important that you close the file, otherwise you will immediately have
a resource leak. Using the `with open(...)` idiom is the standard approach.
