Now lets open Jboss in Web Browser

Lets Verify the Admin Console

Start JBoss 7 as a service on Ubuntu

Previous versions of JBoss included a scripts (like jboss_init_redhat.sh) that could be copied to /etc/init.d in order to add it as a service – so it would start on boot up. I can’t seem to find any similar scripts in JBoss 7.

If you have copied from other editor or any web page then you will find some unwanted character in the file which will give you error when you will try to run the script.

Error: Bad Interpreter…

Verify Interpreter by “which sh” command in console

Result will be /bin/sh

Then verify the script openining it in VI editor.

Error: JBoss 7 as a service on Ubuntu
Error: JBoss 7 as a service on Ubuntu

Remove all unwanted Characters

JBoss 7 as a service on Ubuntu
JBoss 7 as a service on Ubuntu

Save it

JBoss 7 as a service on Ubuntu - Save Changes
JBoss 7 as a service on Ubuntu – Save Changes

Restart the Machine and try following

Restart JBoss Service
Restart JBoss Service

Done!!!
