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

[Scott Marlow (JIRA)]

    [ https://issues.jboss.org/browse/JBAS-9339?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12596929#comment-12596929 ] 

Scott Marlow commented on JBAS-9339:
------------------------------------

Adding configuration for JPA to standalone.xml (and domain/clustering variations):

Default will be:

        <subsystem xmlns="urn:jboss:domain:jpa:1.0">
            <jpa default-datasource=""/>
        </subsystem>

User can use this to specify the default persistence jta-data-source

For example:

         <subsystem xmlns="urn:jboss:domain:jpa:1.0">
            <jpa default-datasource="java:/H2DS"/>
        </subsystem>

> 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:
