Re: [ecf-dev] trouble creating proxy, when my service interface is in a distinct bundle 
Hi David,
Usually, this error is because the bundle that contains the interface (i.e. org.inqle.qa.common.services.IHello class) is not exporting the org.inqle.qa.common.services package. For example, this is from the manifest.mf in the org.eclipse.ecf.examples.remoteservices.hello bundle: 

Export-Package: org.eclipse.ecf.examples.remoteservices.hello,
org.eclipse.ecf.examples.remoteservices.hello.impl

Yours should have something like this in the manifest.mf:

Export-Package: org.inqle.qa.common.services
Only then will the provider's classloader be able to find the class (using the 

Eclipse-BuddyPolicy: global

as you point out).

Thanks,

Scott

Hello again Scott & friends,
My application was working great until I moved my service interface
into a bundle different from my ECF client activator bundle.  Now that
my service (IHello) interface is in a distinct bundle, I get the error
at bottom.  I gather that this bundle is having trouble seeing my
IHello interface:
org.eclipse.ecf.provider.remoteservice_3.1.0.v20091012-1618.jar

however I see that the latter bundle has this in MANIFEST.MF:
Eclipse-BuddyPolicy: global
so I would think it should see my service interface.

Here is my code snippet:

IContainerFactory containerFactory = getContainerManagerService()
				.getContainerFactory();
containerFactory.createContainer("ecf.generic.client");
ServiceTracker serviceTracker = new ServiceTracker(
			bundleContext,
			bundleContext.createFilter("(&("
				+ org.osgi.framework.Constants.OBJECTCLASS + "="
				+ "org.inqle.qa.common.services.IHello" + ")(" +
DistributionConstants.REMOTE + "=*))"),
			this);
		serviceTracker.open();

Any ideas what I am doing wrong?
Thanks much and happy holidays!
