RE: Tomcat dependency on application server
JBoss uses Tomcat as its Servlet container, so there should be no need for a separate tomcat. Can you let us know for what purpose you are using a separate tomcat. ___ Thks brgds P Manchanda On Sun, 18/5/14, Terence M.

Agreed Maybe you should first find out, what your deployment architecture is, and what your app does. Probably ps is a good way to start to find out what is really running on your machine and where. +1. Figure out exactly what's running on your machine, and read architectural documentation why that is. Hopefully, someone documented the architectural decisions your team made. Additional questions to answer: 1) How are you starting your JBoss? How are you starting your Tomcat? 2) How did you find out there are two processes, one for JBoss one for Tomcat? 3) Why do you have two Java processes, one for JBoss and one for Tomcat? 4) What do you deploy to JBoss, what do you deploy to Tomcat? Why? 5) What version of JBoss AS/EAP do you run? This is definitely not a typical JBoss/Tomcat setup, there should be a reason why you have both JBoss and Tomcat. Here are possible confusion points: (a) People often confuse Apache Tomcat with Apache HTTPD (webserver). Apache HTTPD (webserver) is used often as a front for a JBoss, and it is a separate process you run (not Java process, but httpd/httpd.exe compiled natively for your platform). (b) JBoss AS/EAP 5 had a component installed as a jbossweb.sar which is something very similar to Tomcat 6.x codebase, together with server.xml, and other configuration files. We often say JBoss AS5/EAP5 contains Tomcat instance as its servlet container. (c) JBoss AS7/EAP6 doesn't have jbossweb.sar anymore, but has a subsystem defined in JBOSS_HOME/standalone/configuration/standalone.xml under web subsystem. Hopefully that helps! Cheers! n.

Re: Tomcat dependency on application server
Really, there are about 1 gazzillion valid ways to setup an application consisting of n number of tomcats and m number of jbosses, running in same or separate processes/vms/datacenters and doing stuff. Maybe you should first find out, what your deployment architecture is, and what your app does. Probably ps is a good way to start to find out what is really running on your machine and where.
