Reloadable Servlet?

[John Blanco <jb...@tvmax.net>]

	This is one heck of a crach course. :)  OK, I found my 
way through the public_html problem...but now I have a 
question. I want my Servlet to be reloadable.  But, 
when I recompile and make a minor change (changing the 
printed string), I get the dumb that follows below in 
my logs and a 503 return error.

	If I go to TomCat Manager and Stop and then Start (not 
Reload) my Servlet, everything works again until I 
recompile and change.  My question is...does my 
Servlet need to explicitly support a reload?
