Hi Andy,

 -- by hot deployment do you mean you want to be able to deploy a class or
servlet to Tomcat and have Tomcat automatically recognize the new version?
If yes, then checkout the 'reloadable' attribute of the Context Container:

http://jakarta.apache.org/tomcat/tomcat-4.0-doc/config/context.html

FYI: "Set to true if you want Catalina to monitor classes in
/WEB-INF/classes/ and /WEB-INF/lib for changes, and automatically reload the
web application if a change is detected. This feature is very useful during
application development, but it requires significant runtime overhead and is
not recommended for use on deployed production applications. You can use the
Manager web application, however, to trigger reloads of deployed
applications on demand."

If you mean you want to able to hot-deploy an entire application, then
you'll want to check out the Manager application that comes w/ Tomcat:

http://jakarta.apache.org/tomcat/tomcat-4.0-doc/manager-howto.html

The manager is a web application that allows you to:

 -- Deploy a new web application, on a specified context path, from a
specified directory or WAR file pathname.
 -- List the currently deployed web applications, as well as the sessions
that are currently active for those web apps.
 -- Cause an existing application to be reloaded.
 -- Undeploy an existing web application.
 -- Stop an existing application (so that it becomes unavailable), but do
not undeploy it.
 -- Start a stopped application (thus making it available again).

hth,

AJ
