I've got a Linux box where there’s Tomcat running, with some JSP applications in it. Now, I’ve received a third party app from a developer shop to be eventually deployed. It came as an archive called "jboss7.tar" which, it seems, contained a whole standalone Web server. Once I’ve followed their instructions and run the designated shell script, it would start a server that would listen on port 8081, and app pages are being served up.

Still, this strikes me as an inelegant setup. Why run two Web servers side by side, both of them Java-enabled? Also, the manual startup of the standalone app, I don't like that either. The real question is – can I take the user-provided portions from the said archive and somehow plug it under the existing Tomcat instance? It looks like the user code is packaged into files with .war extension, I can see them under /var/jboss7/standalone/deployments.
