TypeUnknownException?

Hello,
 
I have an interface a.b.c.SomeService which defines a service. Now, I would like to replace the implementation in a.b.c.SomeServiceImpl with my own implementation in x.y.z.SomeServiceImpl.
 
In my impl, I have the javadoc like this:
 
@avalon.component version="0.1" name="someService", lifestyle=singleton"
@avalon.service type="a.b.c.SomeService"
 
which is exactly the same as in the original implementation. I see the xinfo for my class is generated and is in the jar file. But when I try to run the code, I see the exception
 
org.apache.avalon.composition.model.TypeUnknownException:Unable to locate a component type descriptor for the component class x.y.z.SomeServiceImpl
 
I am putting my implementation into the same jar as the original implementation. Is that ok? Does somebody know what I could be doing wrong? I am new to merlin.
 
 
Thank you.
