Spring + JTA + Datasource
Hello,
Dans la doc de spring il cite notement ceci pour l'utilisation de JTA en mode managé par le container

If we use JTA in a J2EE container, as in the 'dataAccessContext-jta.xml' file from the same sample application, we use a container DataSource, obtained via JNDI, in conjunction with Spring's JtaTransactionManager. The JtaTransactionManager doesn't need to know about the DataSource, or any other specific resources, as it will use the container's global transaction management infrastructure.

<bean id="txManager" class="org.springframework.transaction.jta.JtaTransactionManager" />
<!-- other <bean/> definitions here -->
</beans> |
cette simple définition nous permet-elle donc de ne rien définir d'autres (sans tx-annotation-driven) et d'utiliser simplement l'annotation @Transactional ?

Peut on combiner la datasource utilisé ici "dataSource" avec la datasource JNDI utilisé plus haut ?

<jee:jndi-lookup id="dataSource" jndi-name="jdbc/jpetstore"/> |
