Declarative JTA transactions XA aware resources auto-enlistment
rules
I've tried and tested declarative transactions with JDBC DataSources using
pax-jdbc. Thanks to
Christian Schneider.
I'v trying to understand the XA aware resources auto-enlistment. But I
cannot found any info. Lack of docs.
All bundle resources are enslisted?
All bundle resources that appears in blueprint config are enslisted?
All karaf platform XA aware resuorces are enlisted?

I tested JTA JPA earlier. It works.
I had problems when tried JTA JDBC. It works too, with pax-jdbc. Pax-jdbc
grants pooling and XA wrapping for DataSources.
When I saw your message, I wanted to try another solution of XA DataSource
auto wrapping. I've tried and it doesn't work. I think it is because of
wrappers bundle absence.
Looked through org.apache.aries.transaction.manager pom.xml. Could not find
wrapper dependency.
Wrappers depends on manager instead.
Is this your framework?

Hum,
I'm not really sure, I don't embed it in my framework, and tx seems to work
(JMS to JPA).
org.apache.aries.transaction.wrappers version is also inferior to
org.apache.aries.transaction.manager
<http://search.maven.org/#search%7Cga%7C1%7Ca%3A%22org.apache.aries.transaction.manager%22>
one,
so I think that Aries developers integrated it in the main bundle (the
manager one).
Concerning how I found the doc, I tried to make XA tx working within an
OSGI project, so crawled the web...
You can take a look at my framework to see how I linked it, but as I said,
I think that it works.

Great docs. How did you find it?
Bundle org.apache.aries.transaction.wrappers doesn't included in Karaf
3.0.3.
Should I install it manually?
Maybe it is some feature that installs it?

As far as I know the auto enlistment happens when a Connection is
created. This Connection will then be enlisted a the TransactionManager
as a resource.
In Aries jpa this happens when the EntityManager is created which
happens at first access to the injected EntityManager proxy.
So in effect the resources are enlisted as you use them.
