ABSOLUTELY NOT!

Do not use singleton in web application, because it raises several 
problem during reloading the webapp.

Instead, you could use a container-managed datasource to call through JNDI:
http://tomcat.apache.org/tomcat-5.5-doc/jndi-datasource-examples-howto.html

Or use Spring or a similar IoC container to configure your Model (this 
is what I prefer to do):
http://static.springframework.org/spring/docs/2.0.x/reference/beans.html#beans-value-element
