JBoss Admin Console
Embedded Jopr in JBoss AS 5.1.0
JBoss AS 5.1.0-CR1 is out and finally includes a brand new admin console:

After installing JBoss AS 5.1.0 you can access it at http://localhost:8080/admin-console. Login with user "admin" and password "admin".
The project behind the admin console is Embedded Jopr a web-based application for managing and monitoring an instance of JBoss AS. It is the little brother of Jopr. Jopr is a full-fledged systems management tool that helps managing and monitoring multiple instances of JBoss AS, Apache Webserver, Tomcat and more. The advantage of Embedded Jopr is that it is available out of the box and does not need any external resources like a database or separate agents. I am sure it makes operating JBoss AS a lot easier and more fun.
Give it a try and download the latest version.
