No idea why the namespace handler does not seem to be present.
You can look through the bundles with la -s and check if the
transaction blueprint 2.0.0 bundle is present.
karaf@root()> la -s | grep transaction
31 | Active | 80 | 1.2 | javax.transaction-api
59 | Active | 80 | 1.1.1 |
org.apache.aries.transaction.blueprint
60 | Active | 80 | 2.0.0 |
org.apache.aries.transaction.blueprint
61 | Active | 80 | 1.3.0 |
org.apache.aries.transaction.manager
You can then do bundle:service -p <id> to see which services it
offers. It should offer the correct blueprint namespace handler.
karaf@root()> bundle:services -p 60
Apache Aries Transaction Blueprint (60) provides:
-------------------------------------------------
objectClass = [org.osgi.service.blueprint.container.BlueprintContainer]
osgi.blueprint.container.symbolicname = org.apache.aries.transaction.blueprint
osgi.blueprint.container.version = 2.0.0
service.bundleid = 60
service.id = 201
service.scope = singleton
----
objectClass = [org.apache.aries.blueprint.NamespaceHandler]
osgi.service.blueprint.compname = nsHandler
osgi.service.blueprint.namespace =
http://aries.apache.org/xmlns/transactions/v2.0.0
service.bundleid = 60
service.id = 273
service.scope = bundle
That all looks good.
If just the EntityManager is missing then maybe the DataSource is not
present or the persistence unit bundle is not correctly identified.
You should see in the log if a persistence unit is found in a bundle
and what it is waiting for.
I am deploying the datasource as a bundle & seems to be registered fine:
karaf@root()> service:list javax.sql.DataSource
[javax.sql.DataSource]
----------------------
osgi.jndi.service.name = hearsayNoJTA
osgi.service.blueprint.compname = hearsay-ds-no-jta
service.bundleid = 268
service.id = 269
service.scope = bundle
Provided by :
Hearsay :: Datasource (268)
[javax.sql.DataSource]
----------------------
osgi.jndi.service.name = hearsayJTA
osgi.service.blueprint.compname = hearsay-ds-jta
service.bundleid = 268
service.id = 270
service.scope = bundle
Provided by :
Hearsay :: Datasource (268)
The persistence.xml file has the following:
<persistence-unit name="hearsay" transaction-type="JTA">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<jta-data-source>osgi:service/javax.sql.DataSource/(osgi.jndi.service.name=hearsayJTA)</jta-data-source>
<non-jta-data-source>osgi:service/javax.sql.DataSource/(osgi.jndi.service.name=hearsayNoJTA)</non-jta-data-source>
I think this configuration all lines up, so I am leaning towards the
"persistence unit bundle is not correctly identified" idea. The dao
impl bundle finally fails with the following exception:
2015-11-30 12:25:48,287 | ERROR | rint Extender: 2 | BlueprintContainerImpl

Is there something else I should be looking for?
Thanks,
Jason
