Ok, I assume that the way I do this is: 1. In jboss-web-tomcat.sar/server.xml, I add "host" sections. I should use a symbolic name, like "foo", not a full hostname, like "foo.com". I put in entries for these with real DNS hostnames. 2. In each of the war files jboss-web.xml, I put <virtual-host>foo</virtual-host>, <virtual-host>bar</virtual-host>, corresponding to each of the symboilc names in server.xml. Is that the right way to do that? I may have gotten it wrong, but I'm now getting all kinds of deployment problems with entities not being mapped.
