By default, JBoss produces output to both the console and a log file (log/server.log). JMX is a reusable and open framework for both local and remote configuration management that supports runtime querying/updates, monitoring, notifications, timers, class loading, etc. Many JSP errors are easier to fix when developers are able to look at the compiled .java files and match the line numbers to error/exception messages. Java Server Pages (.jsp files) are automatically compiled into Java Servlets (.java file) and then into Java byte-code (.class files) by Tomcat . Unpacked deployments (e.g. expanded WAR files) are not copied over. Packed deployments are uncompressed, whereas JARs and XML-described services are copied over.

However, for very simple sites, the drawback of having to set up and manage yet another service typically outweighs the mentioned advantages. If anyone of the JBoss AS nodes fail, the service is still available through other JBoss AS servers. Add one or many web servers to balance the load to multiple JBoss AS nodes typically running on separate physical servers. If the JBoss AS server goes down, the entire service becomes unavailable. All messages received and sent over a Channel have to pass through the protocol stack.
