I migrated to jboss-as-web-7.0.2 and detected late that I need ejb3 timer service
After some research I've find out that I may stay with web profile and only need to change this line:
<subsystem xmlns="urn:jboss:domain:ejb3:1.1" lite="true">
by that ones:
<subsystem xmlns="urn:jboss:domain:ejb3:1.1">
<timer-service>
<thread-pool core-threads="1" max-threads="4"/>
<data-store path="timer-service-data" relative-to="jboss.server.data.dir"/>
</timer-service>
