Chapter 12 Examples from Java Servlet
Programming, 2nd Ed
- 12-1: Snooping the java:comp/env context
Examples from other chapters:
- Example 12.1: Snooping the java:comp/env context
- This servlet displays all its J2EE environment entries, using
the JNDI API to browse the java:comp/env context. All entries
are placed by the server into the java:comp/env context. If you’re
new to JNDI, you can think of this as a URL base or filesystem
directory. The java:comp/env context is read-only and unique per
web application, so if two different web applications define the
same environment entry, the entries do not collide. This feature
is only available to servers supporting J2EE. Jetty (which
we're using here) does not support J2EE, so this will generate
an error.
- Try it (generates an error
because Jetty is not a J2EE server)
