Cor Faber commented on KARAF-6607:
----------------------------------
Thanks for looking into this. Just tried to make a sessionFactory without using
the hibernat.cfg.xml and that did not work.
Within Karaf I see the database when using 'jdbc:ds-list' and with 'jdbc:query
name_datasource "select ..."' I can perform queries on the database. I used the
settings from the corresponding org.ops4j.datasource-name_datasource.cfg to
build the settings in the source code which is used bij the registryBuilder.
While creating registry/MetadataSources/Metadata/SessionFactory I get an
exception after trying to create the Metadata:
'java.lang.ClassNotFoundException: Could not load requested class :
org.mariadb.jdbc.Driver'. Which I don't understand, because the depency is
included in the corresponding pom.xml.
> hibernate.cfg.xml not found - upgrade Karaf 3.0.8 - 4.2.7 / Java 8-9

> Project: Karaf
> Issue Type: Question
> Components: karaf
> Affects Versions: 4.2.7
> Reporter: Cor Faber
> Assignee: Jean-Baptiste Onofré
> Priority: Major
> Attachments: pom.xml

>
> We are upgrading our system from Karaf 3.0.8 to Karaf 4.2.7 and Java 8 to 9
> (10/11 will follow). We use hibernate dependencies to connect to a database.
> In the old version of Karaf we had no issues, but now we have issues
> connecting to the database in our feature. The datasource.cfg is correct and
> within the Karaf console we have no issues performing queries on the
> database, but our feature cannot connect to it. GetSessionFactory
> (ConfigurationException): Could not locate cfg.xml resource
> [hibernate.cfg.xml] is the error we get. The hibernate.cfg.xml is located in
> the main/resources folder and after installing our feature the
> hibernate.cfg.xml can be found in the root of the corresponding bundle.jar in
> the data/cache folder. We also use all the defaults for creating a
> sessionFactory.
> The Java working directory is the base of the apache karaf folder.
> Dependency verions:
> hibernate-jpa-2.1-api.version: 1.0.0.Final
> hibernate-core version: 5.2.10.Final
> hibernate-validator version: 5.2.5.Final
> I've include our pom.xml of our persister. [^pom.xml]
> Any ideas where to start to find a solution for this issue?
