(As asked in title:) How do I tell what version of JBoss I am running?
I am also curious what version of tomcat I am running. Does a specific version of JBoss correspond
This URL (JMX-Console) should provide you the informations
http://localhost:8080/jmx-console/HtmlAdaptor?action=inspectMBean&name=jboss.system%3Atype%3DServer
The tomcat version is implied by the jboss server version.
EDIT:
A complete list of versions you find here VersionOfTomcatInJBossAS
Where you reach your JBoss depends on the interface it is bound, using -b hostname If you start using JBoss with -b 0.0.0.0 option. That way, you can access the system using localhost, machineName and even the IP address. By default it's localhost, if you use th -b option you need to replace localhost by yourhostname.
