Four! I had in mind Class, ClassLoader and ServletContext. Packages don't have methods. -- Lew

I thank you both for clearing that up. I had tried asterisks as wildcards, but the meaning was even less clear. I was intrigued by how the three packages implement the notion of getting a resource: ClassLoader is foundational, while the bean approach "allows a BeanContext implementation to interpose behavior between the child Component and underlying ClassLoader." The ServletContext implementation "does not use class loaders" at all but serves a similar purpose relative to the servlet container's context. This seems like a handy pattern to put in one's hip pocket. -- John B. Matthews trashgod at gmail dot com <http://sites.google.com/site/drjohnbmatthews>

I don't think there were any reason to point out the obvious. Arne |
