Digging some deeper in the environment, I saw that it exists a bundle
(ID=84) that should provide the missing service, so I cannot understand why
this service does not result suitable for other bundles:

> Hi,
>
> I would like to receive some help about a non resolving provider service
> in a very simple test bundle I wrote to test TransactionControl with
> JPAEntityManagerProvider usage with Hibernate on Karaf 4.2.
>
> The core of the program is a "DAO Service" and both interface and
> implementation are reported below.
>
> It seems the bundle hangs waiting for this missing service provider:
> @Reference(target = "(osgi.unit.name=tasklist)")
> void setProvider(JPAEntityManagerProvider provider)
>
> Is anyone so kind to explain me what is missing?
>
> I included the list of features and bundle installed on karaf as well.
>
> I created the datasource this way:
> jdbc:ds-create -dbName reactive -dn mysql -dc com.mysql.jdbc.Driver -u
> root -p root -url "jdbc:mysql://localhost:3306/reactive" reactive
>
> Thanks in advance
