The Spring Framework dataAccessContext-jta.xml source code

<?xml version="1.0" encoding="UTF-8"?>

<!--
  - Application context definition for JPetStore's data access layer.
  - Accessed by business layer objects defined in "applicationContext.xml"
  - (see web.xml's "contextConfigLocation").
  -
  - This version of the data access layer works on two databases (main/order),
  - using JNDI DataSources with JtaTransactionManager. It obviously depends on
  - JTA support in the container, and on pre-configured container DataSources.
  -
  - This version also uses the "jndi:" namespace introduced in Spring 2.0
  - to configured JNDI referenced objects.
