The boot.properties file is used to set several system properties. One system property being set is jboss.server.name, the name of the server configuration. This property corresponds to the value of the minus c option to the run script. The contents of the boot.properties file is shown in the code block below. My guess is that the port number is assigned dynamically because when I cycle the appServer a different port is assigned each time it initializes. And other JBoss510 appServer instances on the same host have different port numbers bound to localhost.localdomain. | jboss.home.dir=/usr2/jboss/jboss-5.1.0.GA | jboss.java.home.dir=/usr2/jboss/jdk1.6.0_06 | jboss.lib.url=file:/usr2/jboss/jboss-5.1.0.GA/lib | jboss.home.url=file:/usr2/jboss/jboss-5.1.0.GA | jboss.server.name=default | jboss.server.base.dir=/jboss/deploy/JBOSS510/JB510.1.0/server/ | jboss.server.base.url=file:/jboss/deploy/JBOSS510/JB510.1.0/server/ | jboss.server.home.dir=/jboss/deploy/JBOSS510/JB510.1.0/server/default | jboss.server.home.url=file:/jboss/deploy/JBOSS510/JB510.1.0/server/default | View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4245859#...
