RE: Manually reloading classes without restarting catalina

[NO...@britbio.co.uk]

Thanks - this has been a great help.

For development purposes I found it eaiser still to remove the
<security-constraint> and <login-config> elements from the web.xml file.
This way you don't have to enter in a password every time.  I know this is
not very secure, but it should be ok in a purely development enviroment.
