Thanks, I was able to get things working by updating the scdl of the das service like this :
<composite xmlns="http://www.osoa.org/xmlns/sca/1.0"; name="DASServiceComposite"> <service name="DASService"> <interface.java interface=" org.apache.tuscany.samples.das.service.DASService"/> <reference>DASServiceComponent</reference> </service> <component name="DASServiceComponent"> <implementation.java class=" org.apache.tuscany.samples.das.service.DASServiceImpl"/> </component> </composite> Basically adding the <service name="DASService"> part.

This is because there is no default service for the composite (we should probably check for this and throw a better error). What seems to be happening is that CompositeComponentExtension.locateService() is resolving to a child composite context which has no default service. It looks as if you are trying to have nested composites. If you do this the DAS component needs to be exposed as a service on the inner composite. Another option would be to point the current composite context to the inner composite (there is a config parameter in the servlet context for this). You should be able to find an example of this in the Spring sample. A further option would be just to have one composite (as opposed to the hierarchy) would make things simpler.
