JBoss AS 7.1.1 does not support WABs out of the box. The following information is buried in the User Guide of JBoss OSGi 1.1.1:

To enable OSGi Web Application support in AS7 you would configure these capabilities

<capability name="org.ops4j.pax.web:pax-web-jetty-bundle:1.1.2"/>
<capability name="org.ops4j.pax.web:pax-web-jsp:1.1.2"/>
<capability name="org.ops4j.pax.web:pax-web-extender-war:1.1.2"/>

Add these lines to the osgi subsystem of standalone.xml and change activation to eager:

 <subsystem xmlns="urn:jboss:domain:osgi:1.2" activation="eager">

Then JBoss AS will download and install the additional bundles during startup. Once these bundles are started, copy your own WAB to standalone/deployments and it should be deployed.

See also this forum post. Note that this WAB runs in a separate servlet container (Pax Web) listening on port 8090 (not 8080).

Also note that these extra capabilities seem to get downloaded again on every server restart. To avoid that, you can manually download the extra bundles (and a transitive dependency) and install them under $JBOSS_HOME/bundles:

org/ops4j/pax/web/jetty/main/pax-web-jetty-bundle-1.1.2.jar
org/ops4j/pax/web/extender/war/main/pax-web-extender-war-1.1.2.jar
org/ops4j/pax/web/jsp/main/pax-web-jsp-1.1.2.jar
org/eclipse/jdt/core/compiler/ecj/main/ecj-3.5.1.jar

And then replace the above capabilities by:

<capability name="org.ops4j.pax.web.jetty"/>
<capability name="org.eclipse.jdt.core.compiler.ecj"/>
<capability name="org.ops4j.pax.web.jsp"/>
<capability name="org.ops4j.pax.web.extender.war"/>
