I defined my datasource in a "extranet-ds.xml" file, deployed in the deploy folder. My DS is set as : | <datasources> | <local-tx-datasource> | <jndi-name>jdbc/TestIntranet</jndi-name> | <connection-url>jdbc:postgresql://192.168.10.108:5432/Intranet</connection-url> | <driver-class>org.postgresql.Driver</driver-class> | <user-name>postgres</user-name> | <password><![CDATA[]]></password> | </local-tx-datasource> | | </datasources> | And it works fine!
