JBoss security: closing unecessary ports

Java App Servers

command: "netstat -tulpn | grep java" gives me the listing bellow.
these are all jboss open ports. some ports listens to localhost and others listens to all interfaces like the port:
tcp        0      0 0.0.0.0:8942            0.0.0.0:*               LISTEN      10333/java
I don't know why jboss would listen to all interfaces, are these ports necessary?

Thanks
