JBoss 7.1.1 + GeoServer 2.2.2

I'm deploying GeoServer 2.2.2 into JBoss 7.1.1 and there are not many hint around on how to solve some issues.

If you download the WAR version of GeoServer and just deploy it into the standalone/deployments folders you get the following errors:

To solve the problem you have to  create two files:
jboss-classloading.xml

<classloading xmlns="urn:jboss:classloading:1.0"
name="geoserver.war"
domain="GeoServerDomain"
export-all="NON_EMPTY"
import-all="true">
</classloading>

jboss-deployment-structure.xml

<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.1">
    <deployment>
        <dependencies>
            <system>
                <paths>
                    <path name="com/sun/imageio/spi"/>
                    <path name="com/sun/imageio/plugins/common"/>
                </paths>
            </system>
        </dependencies>
    </deployment>
</jboss-deployment-structure>

These files have to be added inside the WAR in the \WEB-INF\

This solves the problem and you get a nice and working GeoServer inside the JBoss application server.
