I have deployed many different war files in the JBoss server and as a business requirement people from the other team need to see the list of wars deployed under Jboss along with versions of war files like
There are several MBeans that you can query to determine what WARs have been deployed. Some of them go by the context name, others by the WAR file name. Here are some examples (you can find others in the JMX console):
jboss.web.deployment:war=/XXX (where XXX is the context)
jboss.management.local:J2EEApplication=null,J2EEServer=Local,j2eeType=WebModule,name=XXX.war (where XXX is the WAR file name)
As far a version number go, you will have to handle that on your own. If you let Maven add the version number as part of the WAR file name, then you can extract it from there. Otherwise you will have to write some script/code to extract the version number from within the WAR file (assuming that you or Maven placed it in there somewhere).
