Hi all, 

I don’t know if the questions of Twiddle should be posted in this forum. Please kindly inform me if I posted in the incorrect forum.

My problem is about using twiddle in the cron job. When testing the following command in the command line, it runs successfully.

[root at host]$ /u01/app/jboss/bin/twiddle.sh --server=jnp://server.name:1199 get "jboss.system:service=ThreadPool" "QueueSize"
  | QueueSize=0

But when I run the same command in the cron job, it gives me the following error: 

12:34:02,355 ERROR [Twiddle] Exec failed

I know that the cron job will run in a totally different environment than the environment the user logged into the shell, so is this issue due to the environmental variables of the Java and JBoss? I have already correctly set the JAVA_HOME, PATH environmental variables inside the script. What other environmental variables that I need to set when using the twiddle in the cron job environment.
