Configure JPA to work in the environment
You have developed the applications to work with Java Persistence API (JPA) and now configure your JPA applications to work in the environment. We must specify options for your database as a part of configuring JPA applications. The application server manages access to data sources. We can configure the data sources, connection pooling, and Java Transaction API (JTA) service in the admin console. If we have a specific data source for the application, configure the data source before you install your JPA application.
Procedure
- Configure your data sources through the administrative console. See the topic, Configure a JDBC provider and data source.
- Specify the Java Naming and Directory Interface (JNDI) names for the <jta-data-source> and <non-jta-data-source> elements. For example to use JNDI lookup:
<jta-data-source>jdbc/myJTADataSource </jta-data-source> <non-jta-data-source>jdbc/myNonJTADataSource </non-jta-data-source>If you use the component name space method (for example, java:comp/env) for data source retrieval, ensure that the application defines these resource references so that you can use these JNDI names to access the data source. This component name space configuration provides more flexibility if alter the configuration for the data source. Otherwise, the standard, direct JNDI is used as the data source name. For more information about using the JNDI interface, see the topic, Developing applications that use JNDI. For example, the persistence.xml file would have an entry like the following:
<jta-data-source>java:comp/env/jdbc/DataSourceJNDI </jta-data-source>OR<jta-data-source>jdbc/DataSourceJNDI </jta-data-source>- Configure persistence provider support in the application server.
