Re: Error installing openjpa/3.0.0 in karaf 4.2.7

JB,
  Looking for your input on advantages / disadvantages of three approaches
to JPA for an application upgrade to karaf 4.2.7+.  Logic for the upgrade is
I'm switching from Windows to Linux on the hardware to get cost savings and
want to take advantage of improvements over the last 2 years.  Obviously a
lot will depend on my application but I value your input.

*Background*
In karaf 4.0.10, I use the openjpa feature which installs 13 bundles. 
Following your directions above, in karaf 4.2.7, I'm using openjpa3 which
installs just 1 bundle.

*Options*
1) Don't upgrade karaf
2) Build my own jpa feature that has the capabilities my current version of
code requires, i.e. all 13 bundles
3) Refactor my code to work with the features used in the karaf example jpa

Hi,

I'm not sure to follow your point.

In Karaf 4.2.x, openjpa3 just installs the xbean-asm bundle and the full
"native" openjpa feature.
If you take a look on the openjpa feature:

https://repo1.maven.org/maven2/org/apache/openjpa/openjpa-features/3.0.0/openjpa-features-3.0.0-features.xml

It installs the required bundles and the "main" openjpa 3 bundle.

So it's basically the same.

I would more use directly OpenJPA 3.

Regards
JB
