Hi
you should make an access log with jboss
Example
<subsystem xmlns="urn:jboss:domain:web:1.1" default-virtual-server="default-host" native="false">
<connector name="http" protocol="HTTP/1.1" scheme="http" socket-binding="http"/>
<virtual-server name="default-host" enable-welcome-root="true">
<alias name="localhost"/>
<alias name="example.com"/>
<access-log pattern="%a %t %H %p %U %s " >
<directory relative-to="jboss.server.log.dir" />
</access-log>
</virtual-server>
</subsystem>
You have make a pattern compatible with awstat
