> Key: TUSCANY-169
> URL: http://issues.apache.org/jira/browse/TUSCANY-169
> Project: Tuscany
> Type: Bug
> Components: Java SCA Core
> Versions: M1
> Reporter: Jean-Sebastien Delfino
> Assignee: Jim Marino
> Fix For: M1

> ModuleContext.locateService(serviceName) throws a ServiceUnavailableException if serviceName cannot be found. This is not correct, ServiceUnavailableException is described like this in the SCA 0.9 spec:
> ServiceUnavailableException - signals problems in the interaction with remote services. This
> extends ServiceRuntimeException. These are exceptions that may be transient, so retrying is
> appropriate. Any exception that is a ServiceRuntimeException that is not a
> ServiceUnavailableException is unlikely to be resolved by retrying the operation, since it most likely
> requires human intervention.
> To reproduce the problem. just change the name passed to locateService in the HelloWorldClient sample. You'll get the following exception:
> Exception in thread "main" org.apache.tuscany.core.context.ServiceNotFoundException: HelloWorldServiceComponent2
> at org.apache.tuscany.core.context.impl.CompositeContextImpl.locateService(CompositeContextImpl.java:102)
> at org.apache.tuscany.samples.helloworld.HelloWorldClient.main(HelloWorldClient.java:52)
> A ServiceRuntimeException should be thrown instead of ServiceUnavailableException.
