Easiest way - write a base Servlet class containing the definition of the
method you want
to reuse. Each Servlet that wants to have this method can then extend the
base Servlet:
the base Servlet will be the superclass for a whole bunch of Servlets that
are customised to
a more specific task.
You can even call the base Servlet something like 'BasePlokServlet' - and
make it abstract
to enforce the design decision.

Why? If the method(s) needed by a bunch of Servlets are in some Helper
Class, an instance of which can be a
private member in a BaseServlet, it cannot possibly do any harm - unless the
methods are not thread safe.
