6.3. Accessing the Transaction Manager

download PDF


The easiest way for an application to access the Aries transaction manager inside the OSGi container is to create a bean reference to the OSGi service using Blueprint XML. In fact, you typically need to reference two OSGi services: the JTA transaction manager and the Spring PlatformTransactionManager. These two services access the same underlying transaction manager, but use alternative wrapper layers (see Figure 6.1, “OSGi Transaction Architecture”).

Blueprint XML

In blueprint XML, you can get bean references to the JTA transaction manager instance and to the Spring PlatformTransactionManager instance using the following sample code:
<?xml version="1.0" encoding="UTF-8"?>
<blueprint xmlns=""
        OSGi TM Service
    <!-- access through Spring's PlatformTransactionManager -->
    <reference id="osgiPlatformTransactionManager"
    <!-- access through PlatformTransactionManager -->
    <reference id="osgiJtaTransactionManager"
