Would you not accomplish the same thing by placing it in shared/lib instead of common/lib? My understanding is that common/lib is also used by Tomcat engine itself and also all webapps while the shared/lib is just shared among all webapps? Am I mistaken?

I'll assume you mean shared between separate web applications, as, within a single web app. is nothing special. The key is the classloader. In order for the singleton to be a true singleton, (not one fo reach webapp) it must be loaded rom a common classloader. So the jar it is loaded from should probably be in common/lib. See http://tomcat.apache.org/tomcat-4.1-doc/class-loader-howto.html for more on Tomcat classloader hierarchy.
