6.9.4 Configure JPA-Based Java App as Transaction Participant

Use the information provided in this section to configure Hibernate or EclipseLink as the JPA provider for your Helidon or Spring Boot applications.

Configuring a JPA-Based Java app as a transaction participant is similar to configuring a JDBC-based Java app as a transaction participant.

To configure a JDBC-based Java app as a transaction participant, create a custom data source object and then pass this object to the MicroTx library. In your Java application code, inject a TrmSQLConnection connection object with details of the custom data source, and then update the application code to use the injected object.

To configure a JPA-based Java app as a transaction participant, create a custom data source object and then pass this object to the MicroTx library. In your application code, inject a TrmEntityManager object with details of the custom data source, and then update the application code to use the injected object.

• Configure JPA-Based Java App with an XA-Compliant Resource Manager
  Use the information provided in this section to configure Hibernate or EclipseLink as the JPA provider for your Helidon or Spring Boot applications which participates in an XA transaction when you use an XA-compliant resource manager.
