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>

Or you can generete access log so

You have make a pattern compatible with awstat

Check this url

http://awstats.sourceforge.net/docs/awstats_setup.html

Look for "Access logger" in "$JBOSS_HOME/server/XXX/deploy/jbossweb.sar/server.xml"
