hi,
My test case -- multiple serivces per component run into a familiar
issue like this:
Exception in thread "main" org.osoa.sca.ServiceRuntimeException: The
component doesn't have exactly one service
at
org.apache.tuscany.sca.core.component.ComponentContextHelper.getSingleService
(ComponentContextHelper.java:280)
at
org.apache.tuscany.sca.core.component.ComponentContextImpl.createSelfReference
(ComponentContextImpl.java:121)
at
org.apache.tuscany.sca.host.embedded.impl.DefaultSCADomain.getServiceReference
(DefaultSCADomain.java:379)
at org.apache.tuscany.sca.host.embedded.impl.DefaultSCADomain.getService
(DefaultSCADomain.java:323)
at tuscany.sample.sync.client.Client.main(Client.java:33)
I opened a JIRA 1560 to trace this issue.
