Basic component service operation doesn't seem to match spec
------------------------------------------------------------
Key: TUSCANY-2076
URL: https://issues.apache.org/jira/browse/TUSCANY-2076
Project: Tuscany
Issue Type: Bug
Components: Java SCA Core Runtime
Affects Versions: Java-SCA-1.1
Environment: Windows XP SP2, IBM JDK V5
Reporter: Simon Laws
Fix For: Java-SCA-1.2
samples/calculator uses very basic and minimal SCA confiburation and works just
find. However is you go and extend the composite file slightly changing
<component name="CalculatorServiceComponent">
<implementation.java class="calculator.CalculatorServiceImpl"/>
<reference name="addService" target="AddServiceComponent" />
<reference name="subtractService" target="SubtractServiceComponent" />
<reference name="multiplyService" target="MultiplyServiceComponent" />
<reference name="divideService" target="DivideServiceComponent" />
</component>
To read
<component name="CalculatorServiceComponent">
<implementation.java class="calculator.CalculatorServiceImpl"/>
<service name="CalculatorService">
<binding.sca/>
</service>
<reference name="addService" target="AddServiceComponent" />
<reference name="subtractService" target="SubtractServiceComponent" />
<reference name="multiplyService" target="MultiplyServiceComponent" />
<reference name="divideService" target="DivideServiceComponent" />
</component>
Then I get the following output...
13-Mar-2008 11:19:52
org.apache.tuscany.sca.assembly.builder.impl.CompositeBuilderImpl$1 problem
WARNING: Service not found for component service:
CalculatorServiceComponent/CalculatorService
13-Mar-2008 11:19:52
org.apache.tuscany.sca.assembly.builder.impl.CompositeBuilderImpl$1 problem
WARNING: Service not found for component service:
CalculatorServiceComponent/CalculatorService
13-Mar-2008 11:19:53
org.apache.tuscany.sca.core.assembly.CompositeActivatorImpl activate
WARNING: Skipping component service not defined in the component type:
CalculatorServiceComponent#CalculatorService
If I then go and force the component to recognize the service by adding an
@Service annotation to the calculator component implementation by changing
public class CalculatorServiceImpl implements CalculatorService {
to read
@Service(CalculatorService.class)
public class CalculatorServiceImpl implements CalculatorService {
It then works again.
I believe the spec implies that the basic service definition in the composite
file should be valid without the need to further annotate the service
implementation.
