I am migrating my application from jboss 6 to 7 and I would to use some custom system properties in the standalone.xml for logging and datasource configuration but jboss doesn't resolve them.
I think that Jboss resolves system properties only in some sections of standalone.xml (for example it resolves ${jboss.binding.address} or {jboss.socket.binding.port-offset} in socket and webservice sections).
I have the same problem in JPA persistence.xml inside a jar: i would to point to a different orm file so i can use my application with different dbms (oracle or mysql). In jboss 6 i used this:
<mapping-file>/META-INF/${db.type}/orm.xml</mapping-file>
but jboss 7 doesnt resolve db.type.
However jboss 7 can resolve the following tag in the same file:
<property name="hibernate.dialect" value="${db.dialect}" />
