You are correct, the import and base class is required.

The class name and file name need to match. Much like class hello would
be defined in hello.java, Jython's class hello(HttpServlet) should be in a
hello.py file. Remember PyServlet uses:
PyObject cls = interp.get(name);
and "name" is the filename without the extension.
