[jboss-as7-dev] jboss-admin related question

Hi, I have a scenario like this : (1) I start the standalone mode with the standard standalone.xml (i.e web profile no messaging etc.) (2) I connect to server using jboss-admin. (3) I type help on jboss-admin console and get to see commands like add-jms-topic etc. (4) try executing add-jms-queue command and get the error : "No handler ..." My question : shouldn't jboss-admin query the server for available subsystems and then show the available commands to the user, rather showing a hard coded list of commands to the user? Thx Vimal
