Having @Alternatives for resource definition -------------------------------------------- Key: CDI-409 URL: https://issues.jboss.org/browse/CDI-409 Project: CDI Specification Issues Issue Type: Bug Affects Versions: TBD Reporter: Antonio Goncalves Java EE 6 introduced @DataSourceDefinition and Java EE 7 introduced the same way of defining other resources (JMS factory/destination, Mail factory, JCA connectors....). It would be interesting to have @Alternatives working with these resource definitions. For example you could have a default DS for development : {code} @DataSourceDefinition( className = "org.apache.derby.jdbc.EmbeddedDataSource", name = "java:global/jdbc/devDS", user = "dev", password = "dev", databaseName = "dev", properties = {"connectionAttributes=;create=true"} ) public class DevResources {...} {code} And another DS that would be used, let say, in production as an alternative : {code} @Alternative @DataSourceDefinition( className = "org.apache.derby.jdbc.EmbeddedDataSource", name = "java:global/jdbc/prodDS", user = "prod", password = "prod", databaseName = "prod", properties = {"connectionAttributes=;create=true"} ) public class ProdResources {...} {code}
