If your logger is just an object that needs to be available through out
your application, then you can create it in a startup servlet and then
stick it into the ServletContext with setAttribute().
If your logger is a thread that runs for the life of the application
then you can just start the thread in your startup servlet. The threads
life isn't tied to the object that created it (i think). Some app
servers don't want you creating your own threads for performance reasons
and offer schedule services as an alternative.
