Yes, this line was missing from the example in the PyServlet.java
source.

The .py servlet class must have the same name as the python source. The
source must be called hello.py for the example to work.

This is needed because servlet.jar isn't available on the classpath when
used with tomcat. Without these lines, import javax.servlet would not
work.
