I'm using Ant to compile and create jar file. When jar file is created, and 
when I put Hello.jar file in jboss deploy directory, the server give 11:09:3

ffaele/jboss-3.2.3/server/defau
lt/deploy/Hello.jar
11:09:34,074 INFO  [MainDeployer] Deployed package: file:/home/raffaele/
jboss-3.2.3/server/default/deploy/Hello.jar

and I go to http://localhost:8080/jmx-console/index.jsp jboss.j2ee, nothing 
happened.

The build.xml file is
