Hi, If the component has more than one services, you need to pass in the service name (componentName/serviceName) for the getService() call. The behavior is required by the spec.

Please see if this helps in your case. thanks, but it does not help. I register my service internally using a JavaInterfaceContract in the implementation provider and it is the only service I have. either this code SpliceService spliceService = scaDomain.getService(SpliceService.class, FeedAggregatorComponent/SpliceService); nor the old version below without the /SpliceService work. Any other ideas? Thanks, -Florian In my case, i had a bug where the composite wasn't finding the components, and I was getting the same error message...

Let me see if I can figure out what is causing this, as it's affecting me as well. shall i open a jira issue for that?. -Florian On 8/22/07, Florian Rosenberg [EMAIL PROTECTED] wrote: hi, I'm implementing a component type for running RESTful workflows (or compositions - whatever you wanna call it) within SCA. The implementation worked fine but since I updated to the latest SVN head today it get the following error message when running it. After some time of debugging I couldn't really figure out what the problem is. This is the composite file is like this (the location indicates the directory where to workflows are stored):) component name=FeedAggregatorComponent implementation.splice location=c:/somelocation/ ... / /component Internally in the implementation calls, I register a service called SpliceService as JavaInterfaceContract which is the business interface for talking to my engine. In my test program I have to following: public static void main(String[] args) throws IOException { SCADomain scaDomain = SCADomain.newInstance (FeedAggregator.composite ); SpliceService spliceService = scaDomain.getService (SpliceService.class, FeedAggregatorComponent); spliceService.performReceive(samples/feeds3/., getFeeds, sortSample3, text/plain); System.in.read(); scaDomain.close(); } The exception I receive is the following: - 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 Exception in thread main org.osoa.sca.ServiceRuntimeException: The component doesn't have exactly one service at org.apache.tuscany.sca.core.component.ComponentContextImpl. createSelfReference ( ComponentContextImpl.java:135) at org.apache.tuscany.sca.host.embedded.impl.DefaultSCADomain. getServiceReference ( DefaultSCADomain.java:377) at org.apache.tuscany.sca.host.embedded.impl.DefaultSCADomain.getService( DefaultSCADomain.java:321) at com.ibm.sca.implementation.splice.SpliceScaTester.main
