I believe this is correct: the JNDI resources for a webapp are initialized using the server's ClassLoader, not the webapp's ClassLoader. I'm not entirely sure why this is the case, but it is. For this reason, you must place your JDBC drivers (and anything else required for JNDI resources) in CATALINA_BASE/common/lib (on TC 5.5) or CATALINA_BASE/lib (on TC 6.0), or, define some other ClassLoader that is available /before/ the webapp's ClassLoader becomes useful. > The tomcat installation only runs this one application.

I think this is a reasonable desire, and I'm not sure why Tomcat's architecture does not allow this. Honestly, using the webapp's ClassLoader to create JNDI resources would make a lot of sense and fix at least one long-standing bug/resource leak when restarting webapps. > Its a bit weird that i configure the JNDI resource in the application's > context file but the library that the context file is refering to is to be > kept outside of the application. Agreed. > is there a way i can use the JNDI resource but have the jdbc driver in the > application's WEB-INF/lib directory? This is a bug/feature which must be changed at the Tomcat source level. There is no configuration that can get you what you want.
