Context

[eric <er...@t-online.de>]

Manav,

From the reading I've done it seemed as if you needed a Context but hey, it 
works without one.  Perhaps you need it if, as you say, you need default 
initializations to appear.  I wonder how this would be done on a public 
production server.  I can't imagine letting users modify server.xml.  I'll 
read up some more on this.

You've been a big help.  Thanks!

Eric
