I have seen the source code for a servlet container known as Paperclips and
it uses the method class.newInstance() to create a new instance of the
servlet class. In my opinion other containers must also be doing the same
thing.

I think putting the reference in the ServletContext can help you.
Even if your servlet instance is destroyed and a new instance is created by
the container, you can check for the attribute in the init() method of your
servlet.
But be forewarned. If there is a reload of the web app & the object
referenced is not an instance of a class on the classpath, you may get
ClassCastException.
