The "java:comp/env" context is the J2EE standard location for
components ("comp") provided by the container to the environment
("env") of the application. As such, you will find it to be portable
across any app server that implements JNDI resources in the J2EE
standard way (including Tomcat).

Every server will have it's own way of *configuring* resources into
the standard environment, and those mechanisms will be
server-dependent. However, the application using those resources will
remain portable.

Only if you're using Tomcat. On some other server, you'd use that
server's initialization mechanism -- but your application would still
work.
