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}" /> -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/646650#646650] Start a new discussion in JBoss AS 7 Development at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
