OSGi JPA

Is there an example/tutorial somewhere showing how to persist data using
ServiceMix 4.4 and OSGi? I have tried to use Camel-JPA, Camel-Hibernate, and
many, many other options each with countless classloading issues.

Thanks in advance,

Brian

I don't think you can easily make the tutorial work in karaf 3.x.
The main missing piece is jta 1.2 support which would be difficult to 
provide in karaf 3.x.

So your best bet is to use an older version of the tutorial that was 
deployable on karaf 3.

Hi Christian,

I'm trying to follow your excellent tutorial here:

http://www.liquid-reality.de/display/liquid/2015/03/05/Apache+Karaf+Tutorial+Part+9+-+Annotation+based+blueprint+and+JPA 

I've got it working nicely in standalone karaf 4.0.3 but my requirement for
the project I'm working on is to use servicemix 6.0.0, which only contains
karaf 3.0.5.

I saw that another user had a similar requirement and you suggested manually
installing the additional bundles.  I've tried installing all I can.  I
added the enterprise 4.0.3 repo and manualling installing the latest jpa and
persistence-api features, which seemed to work ok.  However it also looks
for jndi feature, which I hit a block with when I attempted to install jndi
(and others) I get a bigger problem:

java.lang.IllegalStateException: Can't install feature jndi/0.0.0: 	
Can not resolve feature:
Unsatisfied requirement(s):
---------------------------
  
package:(&(package=org.osgi.framework)(version>=1.8.0)(!(version>=2.0.0)))
      Apache Karaf :: JNDI :: Core

How do I resolve this?  

Or alternatively, am I going down the wrong route- instead of trying to
upgrade my karaf install by adding these features, should I instead be
trying to change/remove features from your sample code to enable it to work
in karaf 3.0.5?  If I was to go down that route, could you provide a little
bit of help to get me started please?

Sorry for asking fairly basic questions - I'm completely new to osgi and
karaf/servicemix so am on a bit of a learning curve.

Thanks,

Kevin
