Hi Philipp,
Declarative Services is designed to be an ultra-lightweight injection runtime,
and so it doesn't include the proxying/interception capabilities necessary to
support Declarative Qualities of Service like transactions. This is one of the
primary drivers for choosing blueprint over DS.
There are annotations for managing transactions in Aries blueprint. These are
contained in the latest (1.0.1) release of
org.apache.aries.transaction.blueprint.
You can enable annotation support with the following:
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0";
xmlns:tx="http://aries.apache.org/xmlns/transactions/v1.2.0";>
<tx:enable-annotations/>
<bean id="top" class="org.apache.aries.transaction.pojo.AnnotatedPojo"/>
</blueprint>
I hope this helps!

Hi,
I have a question related to JTA (in JPA) context and SCR:
Is it possible to use the container managed transactions also with SCR/DS? Or
is this only possible via Blueprint?
Furthermore is there any Annotation support for the managing transactions or
must this be done via the Blueprint XML?
CheersPhilipp
