[jboss-user] [Beginners Corner] - Re: How can I find out from command line if JBoss is current

"PeterJ" wrote : You could run a twiddle command to check the value of an attribute of an mbean, such as:
  | 
  | twiddle get "jboss.system:type=Server" Started

  | This is not a perfect solution because this command will yield "Started=true" as soon as JMX and JNDI are running, but HTTP and thus web applications are usually not available until a few seconds later.

Your suggestion implies that if JBoss is not running the above command returns a statement

Started=false

But this is not the case. Instead I am getting an exception (see below).

Is there another solution?
