Never mind – I’m able to
reproduce this now. Hopefully I’ll have something for you shortly.

Hubert,
Can you send me a launch
configuration to test with? We should probably check some of these to make life
easier for adoptors…
Thanks,
Joel

I found a new clue about the problem, but I don't have a solution yet.
The
program fails at line 193 of
org.eclipse.cosmos.me.management.common.util.ManagementProxyFactory. Here
is the stacktrace:
Failed
to register data manager with contribution manager.
java.lang.IllegalArgumentException: interface org.eclipse.cosmos.me.management.provisional.wsdm.capabilities.DescriptionCapability
is not visible from class loader
at
java.lang.reflect.Proxy.getProxyClass(Proxy.java:353)
at
java.lang.reflect.Proxy.newProxyInstance(Proxy.java:581)
at
org.eclipse.cosmos.me.management.common.util.ManagementProxyFactory.getManagedProxy(ManagementProxyFactory.java:193)
at
org.eclipse.cosmos.me.management.osgi.ContributionManagerImpl.manage(ContributionManagerImpl.java:73)
at org.eclipse.cosmos.dc.dataManager.impl.AbstractDataManagerActivator.serviceChanged(AbstractDataManagerActivator.java:92)
The DescriptionCapability class is in management.wsdm bundle, which is not a
dependency of the management.common bundle, where the code fails.
Any
help would be appreciated.
Thanks,

Thanks Bill for the suggestion. I checked my environment, but I only have
the new annotations in my workspace now.
If you run the latest code from CVS, you will be able to invoke APIs of the
data managers, but the data managers can't register with the broker.
Joel, I attached a project set file for getting the minimum number of required
projects into your workspace. Only the example MDR is included.
Thanks,

FYI: I ran into the same
NullPointerException on the exact same line yesterday (along with other problems).
The problems were related to the fact that I was running with both the old and
new annotations in my test environment. When I removed the old annotations from
my environment, all the problems disappeared. So FWIW, double check that your
environment has not mixed the old annotations with the new annotations.
Regards
Bill

Hubert,
I’ve created test cases for this scenario, and they run fine, so
apparently something else is going on. I will try this with the actual class
instead. Is everything I need in CVS at this point, or can you supply a patch
that I can use to reproduce this?
I’ll check my test cases in as well so that you can see them once I get
out of my morning set of meetings.
Thanks,
Joel

Hi Hubert,
Yes, I’ll take a look at it. I don’t think I’ve got a
testcase for the combination of composition and autowire… apparent
oversight on my part.
Thanks,
Joel

Subject: [cosmos-dev] problem with using autowire and
ComposableManagedCapabilitySet together with new annotation
Hi Joel,
I'm having a problem withe the new annotation code. I added the
description capability by jusing the new composability feature like this:
@ComposableManagedCapabilitySet(set={DescriptionImpl.class})
public abstract class
AbstractDataManager implements IDataManager {
After adding the annotation above, the variable that's annotated with @ManagedFrameworkAutowire(name="WSDM") becomes
null.
@ManagedFrameworkAutowire(name="WSDM")
private
Binding wsdmBinding;
public
void
setWsdmBinding(Binding wsdmBinding){
this.wsdmBinding =
wsdmBinding;
}
Object resourceObject = wsdmBinding.getBindingForObject(this); <-- NPE here, wsdmBinding is null.
If I remove the @ComposableManagedCapabilitySet annotation,
the wsdmBinding variable gets the WSDMBinding object.
Can you help me with this problem? You can see the code in the
AbstractDataManager.java file.
Thanks,
