Set the default JTA and non-JTA data source JNDI Names
The JTA and non-JTA data sources to be used for an application can be specified through the <jta-data-source> and <non-jta-data-source> elements of the persistence.xml file within an EJB module.
If these elements are not configured in the persistence.xml file, then the default JTA and non-JTA data sources configured for the server are used. These values are null by default. However, the default JTA and non-JTA data source JNDI names to be used by applications running on this server can be defined using the admin console.
- Open the admin console.
- Select Servers > Application server > server > Container Services.
- Click Default Java Persistence API settings.
- Select the Default JTA data source JNDI name or the Default non-JTA data source JNDI name field.
- Click Apply to save the configuration.
