Congrats! Always feels good to finally make some progress...

WOOT! Lift off! I'd omitted "extends ServiceFactory" from the

That's because I'm transitioning to ipojo; still feeling my way.
Commented that out in the pom and tried again. How is the ipojo
determined?
I imagine here:
<ipojo>
<component classname="com.gestalt.soakit.core.CompositeService">
<provides/>
</component>
<instance component="com.gestalt.soakit.core.Composite"/>
</ipojo>
Exactly, iPOJO will analyze these metadata at runtime (translated in an
internal format) to create and manage factories and instances.
and CompositeService is this
package com.gestalt.soakit.core;
import org.jdom.Element;
import org.osgi.framework.ServiceFactory;
/**
* Defines a component factory service
* that the composite can use to create configured component instances
* as described in an XML component specification.
**/
public interface ComponentService extends ServiceFactory
{
public Component createComponent(Element parentElmt);
}
Pardon the dumb questions; still pretty shaky on all this. Really
wishing I
knew how to make eclipse actually work.

This error is because of the component implementation that doesn't
implement
any service interface (neither directly nor in parent classes). In fact,
component implementations must be concrete classes and not interfaces.
Create an interface with your public Component createComponent(Element
parentElmt) method. Then create a class implementing this interface and
containing your code. The metadata.xml file will describe a component
type
(as yours) but the class name will be the qualified name of the class
implementing your interface.

Clement

In your pom file, why do you have both iPOJO and a bundle
activator. It is
possible to have both, but it's rare because it means that your bundle
contains a mixed set of iPOJO powered components and "regular" OSGi
code.
