Missing warning message when verifying connformance item 50011
--------------------------------------------------------------
Key: TUSCANY-2770
URL: https://issues.apache.org/jira/browse/TUSCANY-2770
Project: Tuscany
Issue Type: Bug
Components: Java SCA Assembly Model
Affects Versions: Java-SCA-1.3
Reporter: Shu Chao Wan
Priority: Minor
I have a question about conformance item 50011 and hope some one could help me.
Conformance item 50011 tells something about some constraints about interface
of <component>'s <reference>. And here is the detailed description:
"A reference has zero or one interface, which describes the operations
required by the reference. The interface is described by an interface element
which is a child element of the reference element. If no interface is
specified, then the interface specified for the reference in the componentType
of the implementation is in effect. If an interface is declared for a component
reference it MUST provide a compatible superset of the interface declared for
the equivalent reference in the componentType of the implementation, i.e.
provide the same operations or a superset of the operations defined by the
implementation for the reference. "
In my opinion, I think it is to say that interface declared for a component
reference must have equal or more operations than its implementation acturally
need. So I write a composite file wire.composite and testcase to verify it.
-----------------------------
wire.composite
-----------------------------
<composite>...
<component name="FComponent">
<implementation.java
class="org.apache.tuscany.sca.vtest.assembly.composite.impl.FServiceImpl"/>
<reference name="d">
<interface.java
interface="org.apache.tuscany.sca.vtest.assembly.composite.DSubService" />
</reference>
<reference name="c">
<interface.java
interface="org.apache.tuscany.sca.vtest.assembly.composite.CSubService" />
</reference>
</component>
<component name="CComponent">
<implementation.java
class="org.apache.tuscany.sca.vtest.assembly.composite.impl.CServiceImpl"/>
<service name="CService">
<interface.java
interface="org.apache.tuscany.sca.vtest.assembly.composite.CService"/>
</service>
</component>
<component name="DComponent">
<implementation.java
class="org.apache.tuscany.sca.vtest.assembly.composite.impl.DServiceImpl"/>
<service name="DService">
<interface.java
interface="org.apache.tuscany.sca.vtest.assembly.composite.DService" />
</service>
</component>
<wire source="FComponent/d" target="DComponent" />
<wire source="FComponent/c" target="CComponent" />
</composite>
---------------------------
FServiceImpl.java
---------------------------
@Service(FService.class)
public class FServiceImpl implements FService {
@Reference
protected CService c;
@Reference
protected DService d;
}
Here, CSubService and DSubService are sub sets of CService and DService
respectively.
When loading this composite file, I haven't got any error message or even
warning message, which supposed to appear.
And when I switch the CSubService to CSuperService and DSubService to
DSuperService (CSuperService and DSuperService are super sets of CService and
DService respectively), I got warning message this time.
WARNING: Component reference interface incompatible with reference interface:
Component = FComponent Reference = d
WARNING: Component reference interface incompatible with reference interface:
Component = FComponent Reference = c
It seems that it works just on the opposite to the specification. Is there
anything wrong with it?
