Hi, If I look into the coding, I would guess, that this is supposed to work (but the code in question has been reworked between 0.3 and 1.0 and the ServiceFactory use case seems to be forgotten in some places). I have opened a bug (https://issues.apache.org/jira/browse/ARIES-1063) for this where I provided this example and a (three line) patch for the issue.

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 [BlueprintContainerImpl.java:393] - Unable to start blueprint container for bundle com.foo.aries.issue org.osgi.service.blueprint.container.ComponentDefinitionException: org.osgi.service.blueprint.container.ComponentDefinitionException: The service implementation does not implement the required interfaces: [com.foo.aries.issue.FooService] at org.apache.aries.blueprint.container.ServiceRecipe.createService(ServiceRecipe.java:297) ~[bundlefile:1.1.0] at org.apache.aries.blueprint.container.ServiceRecipe.internalGetService(ServiceRecipe.java:249) ~[bundlefile:1.1.0] at org.apache.aries.blueprint.container.ServiceRecipe.internalCreate(ServiceRecipe.java:146) ~[bundlefile:1.1.0] at org.apache.aries.blueprint.di.AbstractRecipe$1.call(AbstractRecipe.java:79) ~[bundlefile:1.1.0] at java.util.concurrent.FutureTask$Sync.innerRun(Unknown Source) [na:1.7.0_17] at java.util.concurrent.FutureTask.run(Unknown Source) [na:1.7.0_17] at org.apache.aries.blueprint.di.AbstractRecipe.create(AbstractRecipe.java:88) ~[bundlefile:1.1.0] at org.apache.aries.blueprint.container.BlueprintRepository.createInstances(BlueprintRepository.java:245) ~[bundlefile:1.1.0] at org.apache.aries.blueprint.container.BlueprintRepository.createAll(BlueprintRepository.java:183) ~[bundlefile:1.1.0] at org.apache.aries.blueprint.container.BlueprintContainerImpl.instantiateEagerComponents(BlueprintContainerImpl.java:668) [bundlefile:1.1.0] at org.apache.aries.blueprint.container.BlueprintContainerImpl.doRun(BlueprintContainerImpl.java:370) [bundlefile:1.1.0] at org.apache.aries.blueprint.container.BlueprintContainerImpl.run(BlueprintContainerImpl.java:261) [bundlefile:1.1.0] at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) [na:1.7.0_17] at java.util.concurrent.FutureTask$Sync.innerRun(Unknown Source) [na:1.7.0_17] at java.util.concurrent.FutureTask.run(Unknown Source) [na:1.7.0_17] at org.apache.aries.blueprint.container.ExecutorServiceWrapper.run(ExecutorServiceWrapper.java:106) [bundlefile:1.1.0] at org.apache.aries.blueprint.utils.threading.impl.DiscardableRunnable.run(DiscardableRunnable.java:48) [bundlefile:1.1.0] at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) [na:1.7.0_17] at java.util.concurrent.FutureTask$Sync.innerRun(Unknown Source) [na:1.7.0_17] at java.util.concurrent.FutureTask.run(Unknown Source) [na:1.7.0_17] at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$201(Unknown Source) [na:1.7.0_17] at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(Unknown Source) [na:1.7.0_17] at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) [na:1.7.0_17] at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) [na:1.7.0_17] at java.lang.Thread.run(Unknown Source) [na:1.7.0_17] Caused by: org.osgi.service.blueprint.container.ComponentDefinitionException: The service implementation does not implement the required interfaces: [com.foo.aries.issue.FooService] at org.apache.aries.blueprint.container.ServiceRecipe.validateClasses(ServiceRecipe.java:340) ~[bundlefile:1.1.0] at org.apache.aries.blueprint.container.ServiceRecipe.createService(ServiceRecipe.java:289) ~[bundlefile:1.1.0] ... 24 common frames omitted 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?
