The Context

JNDI works with one or more contexts. A context is effectively a namespace, and within a namespace are resources that are identified by a key. A resource is an object that is stored or bound into the namespace using a key and can be retrieved by the key. Namespaces can optionally form a hierarchy much like a directory hierarchy, so that a series of entries relating to computer servers could be organized as follows.
