I have a requirement to setup 2 instances of same application (one for live and one for testing) running on jboss 4.2.3.GA. I don't want to run multiple instances of Jboss server since it requires changing all the listening ports, so i decided to move the "hard-coded" actual jndi name from my ejb3 sessionbean (I'm using @javax.annotation.Resource injection currently), i tried and failed to lookup the datasource using: (in sessionbean) Context ic = new InitialContext(); ds = (DataSource) ic.lookup("java:comp/env/jdbc/ds_name"); (ejb-jar.xml) <enterprise-beans> <ejb-name>AdmResourceFacade</ejb-name> com.tims.ac.service.AdmResourceFacade <ejb-class>com.tims.ac.service.AdmResourceFacadeImpl</ejb-class> <session-type>Stateless</session-type> <transaction-type>Container</transaction-type> <resource-ref> <res-ref-name>jdbc/ds_name</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> </resource-ref> </enterprise-beans> (in jboss.xml) <enterprise-beans> <ejb-name>AdmResourceFacade</ejb-name> <resource-ref> <res-ref-name>jdbc/ds_name</res-ref-name> <jndi-name>java:/actual_ds_name</jndi-name> </resource-ref> </enterprise-beans> i get javax.naming.NameNotFoundException: jdbc not bound when looking up the datasource, please help.
