[jboss-jira] [JBoss JIRA] Commented: (JBAS-9339) Provide jta-data-source if not specified

[Jesper Pedersen (JIRA)]

    [ https://issues.jboss.org/browse/JBAS-9339?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12596208#comment-12596208 ] 

Jesper Pedersen commented on JBAS-9339:
---------------------------------------

There is no DefaultDS in AS 7. It is up to each subsystem to create their own. Of course if multiple datasources are needed across subsystems they should use the same.

> Persistence 2.0 Spec, Chapter 8.2.1.5
> In Java EE environments, the jta-data-source and non-jta-data-source elements are used to specify the global JNDI name of the JTA and/or non-JTA data source to be used by the persistence provider.
> and need to provide one if it is not specified:
> If neither is specified, the deployer must specify a JTA data source at deployment or a JTA data source must be provided by the container, and a JTA EntityManagerFactory will be created to correspond to it.
> Without the jta-data-source element in the persistence.xml, the deployment fails to start:
