Nicolas Duminil commented on KARAF-6019:
----------------------------------------

My settings.xml is fine, nothing special there. However, modifying the 
karaf-jpa-example-provider/pom.xml by commenting out the 
karaf-jpa-example-provider-ds module, as follows:

    ~<modules>~
        ~<module>karaf-jpa-example-provider-api</module>~
        ~<!--module>karaf-jpa-example-provider-ds</module-->~
        ~<module>karaf-jpa-example-provider-blueprint</module>~
    ~</modules>~

doesn't raise any more the exception. That's fine as I didn't need to use the 
declarative services. But still, it's weird and I don't have any explanation. I 
googled for a while and found some posts about maven-bundle-plugin but nothing 
very clear. I'll keep searching. Okay for the chat, skype would be fine. My 
skype ID is nicoas.duminil1. If you want, we can chat tomorrow after 11:00 AM 
CET~.~

> Hello,
> I'm following the tutorial here 
> ([https://github.com/apache/aries-jpa/tree/master/examples)] to run the 
> aries-jpa examples, but unsuccessfully. The README.md file says to performa 
> the following operations:
> ~feature:repo-add mvn:org.ops4j.pax.jdbc/pax-jdbc-features/0.8.0/xml/features~
> ~feature:install scr transaction pax-jdbc-config pax-jdbc-h2 
> pax-jdbc-pool-dbcp2 http-whiteboard jpa hibernate/4.3.6.Final~
> The last command displays the following error message~:~
> ~Error executing command: No matching features for 
> hibernate/[4.3.6.Final,4.3.6.Final]~
> So I'm doing just:
> ~feature:install scr transaction pax-jdbc-config pax-jdbc-h2 
> pax-jdbc-pool-dbcp2 http-whiteboard jpa hibernate~
> and this works. Looking at the installed features I have:
> ~karaf@root()> feature:list | grep hibernate~

> After that, the document instructs to do that:
> ~install -s mvn:org.apache.aries.jpa/org.apache.aries.jpa.blueprint/2.3.0~
> ~install -s 
> mvn:org.apache.aries.jpa.example/org.apache.aries.jpa.example.tasklist.model/2.3.0~
> ~install -s 
> mvn:org.apache.aries.jpa.example/org.apache.aries.jpa.example.tasklist.blueprint/2.3.0~
> This works as expected but, when I go to [http://localhost:8181/tasklist] I 
> get the following in the log:
> ~15:16:06.199 ERROR [Blueprint Extender: 3] Unable to start blueprint 
> container for bundle org.apache.aries.jpa.example.tasklist.blueprint/2.3.0 
> due to unresolved dependencies 
> [(&(osgi.unit.name=tasklist)(objectClass=javax.persistence.EntityManager))]~
> Since this is the official sample supposed to prove that the whole stuff is 
> working I would expect it to work as it is, without doing any particular 
> thing. But for some reasons it doesn't. I have seen this issues reported 
> several times but no solution. Please help.
> Oh, and *the version I'm using is 4.2.0.fuse-710024-redhat-00002*
> Kind regards,
> Nicolas
