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
