Florian Rosenberg commented on TUSCANY-1560:
--------------------------------------------
I had the same issue as stated above. The first one was a warning as shown
below:
--------------------------------------------------------------
Aug 22, 2007 12:17:38 PM
org.apache.tuscany.sca.assembly.builder.impl.CompositeBuilderImpl$1 problem
WARNING: [WARNING] No implementation for component: FeedAggregatorComponent
null
--------------------------------------------------------------
The error was in definition of the
org.apache.tuscany.sca.contribution.processor.StAXArtifactProcessor file. The
contents of this file is shown below:
com.ibm.sca.implementation.splice.SpliceArtifactProcessor;type=http://www.osoa.org/xmlns/sca/1.0#implementation.splice,model=com.ibm.sca.implementation.splice.SpliceImplementation
but actually the "type=" is now "qname=".
The second exception (show below) can be either a result of the warning above
or a change in the runtime behavior as state by Luciano on the mailing list.
So if you have a getService("ABC") in your client you need to make sure that
the target component has only one service, otherwise you should use
getService("ABC/ServiceName").
--------------------------------------------------------------

doesn't have exactly one service
