I'd like to set up a custom log pattern for access logging in jboss7.

I entered the following in standalone.xml:

<subsystem xmlns="urn:jboss:domain:web:1.0" default-virtual-server="default-host">

    <connector name="http" protocol="HTTP/1.1" socket-binding="http" scheme="http"/>

    <virtual-server name="default-host" enable-welcome-root="true">

        <alias name="localhost"/>

        <alias name="example.com"/>

            <access-log pattern="&#37;h &#37;l &#37;u &#37;t &#37;T &#37;D &#34;&#37;r&#34; &#37;s &#37;b &#34;&#37;{Referer}i&#34; &#34;&#37;{User-Agent}i&#34;" />

    </virtual-server>

</subsystem>

This seems to work as it should, but when I look at standalone.xml after startup it is changed to:

<subsystem xmlns="urn:jboss:domain:web:1.0" default-virtual-server="default-host">

    <connector name="http" protocol="HTTP/1.1" socket-binding="http" scheme="http"/>

    <virtual-server name="default-host" enable-welcome-root="true">

        <alias name="localhost"/>

        <alias name="example.com"/>

        <access-log/>

    </virtual-server>

</subsystem>

How do I get my pattern to stay in my config?
