Hi all,

Not sure I can post this question here, so if not, maybe someone knows where I 
should ask it.

My question: 


* in short: How do I get started with Aries JPA in combination with Apache 
Felix?

* in detail:


I am trying to get started with Aries JPA in Felix but until now all my 
attempts failed.

There doesn't seem to be some easy way such as 

- install these bundles in a clean Apache Felix
- start all bundles and explore this URL

- examine this source of the example.

Of course there are some samples like 
"http://aries.apache.org/modules/samples/blog-sample.html";
But they all require quite some setup.
In the case above (blog-sample), one should start building the Aries 
development stream and then run the example in "Eclipse Equinox" (not Felix 
!?!).

I tried building but - as I am not so good at Maven - I cant get the code of 
the Aries development stream to compile.
I get some Maven issues (in Eclipse Indigo, m2e 1.0.200) such as
-  Plugin execution not covered by lifecycle configuration: 
org.apache.maven.plugins:maven-antrun-plugin:1.2:run (execution: create-prop, 
phase: initialize)

-  Missing artifact biz.aQute:bndlib:jar:0.0.313
-  maven-enforcer-plugin (goal "enforce") is ignored by m2e.

Next I tried just to download the ready-built bundles from
- http://aries.apache.org/downloads/currentrelease.html
But I could not find a nice checklist and thus it was guessing which bundles to 
install.
I ended up with this set:

------------------------------------------------------------------------------
This is a combination of
1) Clean Apache Felix 4.0.2
2) Aries bundles (blueprint, jpa, proxy)
3) OpenJPA 2.2.0
4) asm-3.1-osgi.jar (I had to download somewhere)
5) slf4j and log4j (I had to download somewhere)

When starting up I get 

ERROR: Bundle org.apache.openjpa [16] Error starting 
file:/C:/Data/tools/felix-framework-4.0.2-Aries/plugins/openjpa-2.2.0.jar 
(org.osgi.framework.BundleException: Uses constraint
violation. Unable to resolve bundle revision org.apache.openjpa [16.0] because 
it is exposed to package 'javax.transaction.xa' from bundle revisions 
org.apache.geronimo.specs.geron
imo-jta_1.1_spec [34.0] and org.apache.felix.framework [0] via two dependency 
chains.

Chain 1:
  org.apache.openjpa [16.0]
    import: 
(&(osgi.wiring.package=javax.transaction.xa)(version>=1.1.0)(!(version>=1.2.0)))
     |
    export: osgi.wiring.package=javax.transaction.xa
  org.apache.geronimo.specs.geronimo-jta_1.1_spec [34.0]

Chain 2:
  org.apache.openjpa [16.0]
    import: 
(&(osgi.wiring.package=javax.persistence)(version>=1.1.0)(!(version>=2.1.0)))
     |

     |
    export: osgi.wiring.package=javax.sql; uses:=javax.transaction.xa
    export: osgi.wiring.package=javax.transaction.xa
  org.apache.felix.framework [0])

I have no Idea how to fix (can't leave out geronimo-jta_1.1_spec-1.1.1.jar)

---------------------------------------------------------------------------------------------------------------------
---------------------------------------------------------------------------------------------------------------------
So does anyone know about a clean check-list of how to get started?
- Install this set of bundles (Aries, openJPA, log,... ?)
- Install these sample bundles
- Ready
?

Thanks a lot!
