Eclipselink with Apache Felix [message #390033]

Thu, 09 July 2009 11:14

Eclipse User

Hi all,

I am trying to run a simple test bundle, which uses Eclipselink on Apache
Felix, however due to dependencies I had to install the bundle
org.eclipse.osgi_3.4.3.R34x_v20081215-1030.jar, because I got the error:
java.lang.NoClassDefFoundError:
org/eclipse/osgi/internal/baseadaptor/DefaultClassLoader

however when I install the bundle
org.eclipse.osgi_3.4.3.R34x_v20081215-1030.jar
I got the following error:

ERROR: Error starting
file:bundle/thirdparty/eclipselink/org.eclipse.osgi_3.4.3.R3 4x_v20081215-1030.jar
(org.osgi.framework.BundleException: Activator start error in bundle
org.eclipse.osgi [10].)
java.lang.ClassCastException:
org.eclipse.osgi.framework.internal.core.SystemBundleActivat or cannot be
cast to org.osgi.framework.BundleActivator
at org.apache.felix.framework.Felix.createBundleActivator(Felix .java:3350)

It seems that eclipselink runs only on Eclipse equinox? Can anybody
confirm that?

Thanks in advance,

-Omar Diego

Can you provide the stack? You're probably deploying the Equinox JPA
bundle which you shouldn't do when running on Felix.

EclipseLink works great on Felix and Sun has been using it in GlassFish V3
(running on Felix) for some time. The EclipseLink team is working with
the GlassFish team to ensure it works well because EclipseLink is the JPA
2.0 reference implementation and will ship in GlassFish as a component in
the Java EE 6 reference implementation stack.

Hi Shaun,

I removed the Equinox JPA bundle from my environment, but I am still
having errors (see below). I am traing running the sample with OSGi that
it is available in the eclipselink website:
http://wiki.eclipse.org/EclipseLink/Examples/OSGi/Developing _with_EclipseLink_OSGi_in_PDE

Thanks in advance,

It looks like we are getting the version of QName that is included in the
JDK from Equinox. It is worth filing a bug for this.

We are in the middle of a transition to use BND to generate our manifests.
When that transition is complete, issues like this should go away.

I am not familiar with Felix configuration, but if there is a way to
configure it to allow QName to be part of the system, that would be one
workaround.

Otherwise, it is probably a matter of hacking org.eclipse.persistence.core
to import javax.xml.namespace. (if you do not have a bundle that exports
it, our javax.xml.stream_1.0.1.v200903100845.jar does)

Hi,

Was a bug raised for this? I am trying to use EclipseLink 1.3.0 with Felix and I am getting the same error with the QName class.

Where would I find the javax.xml.stream_1.0.1.v200903100845.jar?

Thanks in advance for any help on this.

Cheers,
-Lyndon-

I assume you mean your using 1.1.3. Try the 1.2 or the 2.0 builds, the manifest in these should be more up to date.
