There is a section in there called "Advanced Configuration - Multiple Tomcat Instances". We segregate our 4 webapps in this way and it works very well for us. Some things to remember: 1. Since only one process can bind to an IP/port combination, you will need some type of front controller configured to route requests to the proper Tomcat instance. We use Apache httpd + mod_jk to map URL patterns (like /webapp1 -> tomcat1, /webapp2 -> tomcat2). You will have to be very careful about port assignments, since each Tomcat instance needs at least 1 port for requests (like 8080 or whatever) as well as a shutdown port (which you can disable if you choose) and these need to be unique across all your instances. So, if you need 4 Tomcats, you need 8 ports allocated. I recommend you establish a convention such as Tomcat 1 = 8001,9001, Tomcat 2 = 8002,9002 or something like that just to keep your sanity. 2. More JVMs means larger memory requirements. A Sun 1.5+ JVM will help, as some of this memory is shared, but you'll still need a bunch of memory to hold all those heaps. Our 4 (modest) webapps fit comfortably inside 2GiB of memory.
