Hi,
I am trying to upgrade the blueprint implementation from aries blueprint 0.3.1
to aries blueprint 1.1.0, but I am having issues with OSGi services based on a
ServiceFactory.
If I set up the following project:
package com.foo.aries.issue;
public interface FooService {
}
package com.foo.aries.issue.impl;
import com.foo.aries.issue.FooService;
public class FooServiceImpl implements FooService {
}
package com.foo.aries.issue.impl;
import org.osgi.framework.Bundle;
import org.osgi.framework.ServiceFactory;
import org.osgi.framework.ServiceRegistration;
import com.foo.aries.issue.FooService;
public class FooServiceFactory implements ServiceFactory<FooService> {
@Override
public FooService getService(Bundle bundle, ServiceRegistration<FooService>
registration) {
return new FooServiceImpl();
}
@Override
public void ungetService(Bundle bundle, ServiceRegistration<FooService>
registration, FooService service) {
}
}
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="
http://www.osgi.org/xmlns/blueprint/v1.0.0
http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd";>
<service id="fooService" interface="com.foo.aries.issue.FooService">
<bean class="com.foo.aries.issue.impl.FooServiceFactory"/>
</service>
</blueprint>
the bundle starts the service on aries blueprint 0.3.1, but on aries blueprint
1.1.0, I get the following error:
14:13:09.994 ERROR [Blueprint Extender: 2] o.a.a.b.c.BlueprintContainerImpl

What's wrong here? Is this not supposed to work and works only accidentally
with aries blueprint 0.3.1? How can I set up a ServiceFactory with aries
blueprint 1.1.0? Does anybody here have a clue about this?
Best regards
Stephan
