Subject Configuring a web application at the container level
Date Wed, 15 Feb 2006 16:55:44 GMT
Hi all,

  Here's a newbie question -- I'm looking forward to RTFM :)  I would
like to find a consistent way to do application-specific configuration
of a web application.  Is there a best-practice for this that you might

  Consider the following example.  I have a hello world application that
contains one servlet, which outputs the string "Hello World".  The
application is bundled in hello-world.war, which I will then deploy in
various tomcat instances.  

  Now, if I want to make the output string configurable, I might make an
entry in web.xml for this.  If I do it this way, then, at each
deployment, I have to unpack the web.xml and edit it to include the
correct configuration setting (e.g. "Hello World, from your friends at").  Yuck.  I'd much rather put these configuration settings
in a central file or registry for each tomcat instance, and then
hello-world.war could just inherit those settings from the container.
That way I edit the configuration file once, and each re-deploy doesn't
require a re-edit of the configuration file.

  So, how do I do that?  JNDI, JMX, something else?    

  Thanks for considering this question.
