Re: Felix OSGi and EclipseLink issue

Sat, 27 Mar 2010 08:52:17 -0700 

Hello Aerv,
I'm away from the office at the moment, but if I recall correctly the eclipselink osgi example needs to be tweaked to work under Felix because it uses some equinox specific extensions. 


I have a simple JPA with eclipselink example that runs with Felix/ 
Karaf. I can push that out somewhere for your reference when I get  
back to the US on Monday.


Best,
Andreas

I'm not sure I understand what you mean. I have to run it in Felix.  
I'm
trying to start from this example to import my own entities aftwards  
and
create my own jpa bundle for a felix framework. But well, if I can't  
get

this example working, then there's not much point to it. :-(

When I run it as in the tutorial

(http://wiki.eclipse.org/EclipseLink/Examples/OSGi/Developing_with_EclipseLink_OSGi_in_PDE 
)

in Equinox, I get the standard output:
sgi> Persistence bundle starting...
Persistence bundle started.
ProviderTracker: New service detected...
ProviderTracker: Added service
org.eclipse.persistence.jpa.osgi.PersistenceProviderOSGi
[EL Config]: The access type for the persistent class [class
hello.jpa.Person] is set to [FIELD].

[EL Config]: The alias name for the entity class [class  
hello.jpa.Person] is

being defaulted to: Person.

[EL Config]: The table name for entity [class hello.jpa.Person] is  
being

defaulted to: PERSON.....

I just want to get the same result in the Felix framework.


Thanks for the reply though. If I am not understanding you  
correctly, you're
welcome to point it out. I'm not too familiar with OSGi in general.  
Just
trying to export Entity classes and DAO's to a Felix bundle, and  
well, I

thought I'd start with the example

Sincerely,

Aerv

If your intention is to use JPA in an OSGi environment, I recommend

to try out running in GlassFish. You don't have to do anything new to
get it working.

Hello,

I'm new to Felix OSGi, and have tried this simple example:

http://wiki.eclipse.org/EclipseLink/Examples/OSGi/Developing_with_EclipseLink_OSGi_in_PDE 
.
In Equinox everything works great if I follow the steps in the  
tutorial.

However, I want to set it up in a Felix framework.

I have followed

http://felix.apache.org/site/integrating-felix-with-eclipse.html  
to get
Felix within Eclipse. This also works, and the basic examples for  
this

work

aswell. However, when I try to get EclipseLink working in Felix I  
get an

exception:

I've been looking into this for days. And I can't figure out how  
to get

this
simple example working. I have tried to make it work with Pax Runner
aswell,
but no success.

If anyone can help me, it would be very much appreciated.

Thanks in advance.
