[ https://issues.jboss.org/browse/WFLY-4296?page=com.atlassian.jira.plugin.... ] Tomaz Cerar commented on WFLY-4296: ----------------------------------- This is being removed as it cannot be properly supported/implemented in all scenarios in which server and its tooling operates, and as such is causing more problems that it solves. Currently only scenario where it kinda works ok is in standalone mode when you are doing application developing. And when you keep this in mind you can see that EE6+ feature http://docs.oracle.com/javaee/7/api/javax/annotation/sql/DataSourceDefini... more than satisfies it. What it lacks is if nothing else full support for deployment in domain, runtime statistics & management operations. This brings confusion to users as data sources behave differently depending how they are deployed. When this was initially implemented it was only done to ease migration from AS < 7 to 7+ where this was only way to deploy datasources. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
