The Bookrepository uses Aries JPA. The class is marked @Transactional.
So it will start an XA transaction before each call or join one.
For the camel route that start with jms: the JMSComponent is injected
with a PlatformTransactionManager. This causes camel to start a
transaction before receiving each message
and commit or rollback when the route is finished. I also used the
transacted() dsl which starts a (required) transaction but I am not sure
if it is needed.
In any case the log I pasted shows that the XA transaction really
happens (at least I hope so).

What is the actual code doing XA? I look at the examples and I
couldn't pinpoint one.

I am currently doing a demo for XA transactions that should show how to
combine JMS and JPA in one transaction.

I am pretty sure my setup for the XA Transactions is correct now. In my logs
I see that JMS participates in the transaction and that the transaction is
rolled back.

I would expect that now ActiveMQ redelivers the message 3 times like I set
it up. This does not seem to work though. For each redelivery I should get
an exception and the rollback in camel but I only see it once.
This is my setup for the ConnectionFactory:
https://github.com/Talend/tesb-rt-se/blob/ebook-example/examples/tesb/ebook/ebook-connectionfactory/src/main/resources/OSGI-INF/blueprint/blueprint.xml
and this is my camel setup :
https://github.com/Talend/tesb-rt-se/blob/ebook-example/examples/tesb/ebook/ebook-importer/src/main/resources/OSGI-INF/blueprint/blueprint.xml
Any idea what I am doing wrong?
