If I deploy a WAR file while Tomcat is running, is there a way to load (or reload) it without restarting Tomcat?

If you are using Tomcat 4, you can reload, start or stop a particular context through "Tomcat Manager Application". The available commands for the Manager application are:

http://localhost:8080/manager/install?path=/xxx&war=yyy - 
	Install the web application whose WAR file (or directory 
	containing the unpacked application) is present at URL yyy, 
	and attach it to context path /xxx. See below for valid syntax 
	options for the web applcation archive URl. If the URL of an actual 
	WAR file is specified, the WAR will be automatically expanded 
	into a directory underneath the application base for this virtual host. 

http://localhost:8080/manager/list - List the context paths of all currently 
	installed web applications for this virtual host. Each context will be 
	listed with the following format path:status:sessions. Where path is 
	the context path. Status is either running or stopped. Sessions is 
	the number of active Sessions. 

http://localhost:8080/manager/reload?path=/xxx - Cause the web application 
	installed at context path /xxx to reload all its associated Java 
	classes, even if automatic reloading is disabled. 

http://localhost:8080/manager/remove?path=/xxx - Cause the web application 
	installed at context path /xxx to be gracefully shutdown and 
	delete the web application directory and files. 

http://localhost:8080/manager/sessions?path=/xxx - List session information 
	about the web application attached to context path /xxx for this 
        virtual host. 

http://localhost:8080/manager/start?path=/xxx - Start the web application 
	attached to context path /xxx for this virtual host. 

http://localhost:8080/manager/stop?path=/xxx - Stop the web application attached 
	to context path /xxx for this virtual host.
