I got it working while creating the features myself.
Hi,
did you see my message?
Is the feature still in progress or is it just me that did not find it?

Hi JB,
can you point me to the feature repositories I need to add to Karaf
4.2.6 to use OSGi R7 transaction control and JPA?

Hi,
The model is the way it is quite deliberately, and there are several usage

Actually, I took a stab at this again since I had some spare time now. I am
almost done. It looks promising.
The only question I have is about the entity manager. In the examples, I see
an entity manager is obtained in the activate method, and used for the rest of
the life of the component:
Thanks for the feedback Tim.
I created the following Jira to add a example about tx in general and
tx-control in particular:

Hi Alex,
yes it is possible to use tx-control with Karaf, we have been using it on
v4.0.5 in our production system for about 18 months with no issues. One of
the main reasons we use tx-control is that is it 'backed' by a standard.
Rightly or wrongly we also didn't have confidence in Aries JPA Temp

As has been discussed on the Aries lists before, I have no problem with

This is not something that I have the time to do, but another implementation of
a transaction control service with a pluggable transaction manager would be a
great addition.

Hi Tim.
I'm using the 2.6.1 version of aries jpa support already. Normal
transaction control with blueprint and @Transactional annotation was
working fine.
To have better control over startup dependencies and cope with
disappearing and appearing services during runtime we invest some time
Hi Alexander,
That looks like it should be fine - what version of Aries JPA are you using?
There were some fixes made to Aries JPA in 2.4.0 to add support for JPA 2.1
configuration properties which are needed by the transaction control
implementation, and I think that there were then more

I use a JPAEntityManagerProviderFactory (providerFactory) which I

Hi Alexander,
Do you have a code example of how you’re obtaining and using the EntityManager?
There should be no usage of the OSGiJtaPlatform from the tx-control XA JPA

provider, or something is misconfigured. If you are a
