Thanks for the reply i have two more question i dont know what is meant by
(right click, full publish) or touch the descriptor (in JBT there is the "touch" button to do this) as i am new to jboss and sorry this may be dump question what i did was i simply copied archive file i.e jar file of a module and pasted into lib folder where it was originally there as cannot deleted ( i get message that it is being used) and simply touched application.xml file altough application was reployed but dint reflect any changes please give some more insight.
