How to check if JBoss is running on Unix server?

Question

I have a script below that I'd like to echo out "jboss not running" or "jboss is running" depending on whether it can find the jboss process in the process list. However, when I shut down Jboss it still executes the Else condition and says "jboss is running". If I manually do "pgrep -f jboss" it doesn't return anything, so why is it still going into the Else condition? puzzled

#!/bin/bash
if [ -z "$(pgrep -f jboss)" ]
  then
  echo "jboss is not running"
else
  echo "jboss is running"
fi 

Thanks for your help!

The best way is use this

result=`$jboss/bin/jboss-cli.sh --connect controller=localhost:$controller_port --commands=\"read-attribute server-state\" > out 2&1`
echo "$result" | grep -q "running"
if [ $? -eq 0 ];then 
   echo "Jboss running"
fi

If you want to check if ear or war file is deployed then you could use the following command

$JBOSS_HOME/bin/jboss\-cli.sh --connect controller=localhost:$PORT  --command="deployment-info --name=$YOUR_WAR_OR_EAR_FILE"
