When I use a wire:
<wire source="AComponent/bReference>
target="BComponent//BImplementation"/>
to wire two components, I get the exception at the end of this message.
This does not happen when I wire the components using a reference on the
component:
<component name="AComponent>
<reference name="bReference" target="BComponent"/>
</component>
I then looked at the integration test:
org.apache.tuscany.sca.itest.WireTestCase.java which is part of the
source distribution. It utilizes the following wire:
<wire source="WireClient/aWireService"
target="WireService/WireService"/>
This test does run successful but that is because the name of the
component and service are equal!!!
If one changes the name of the component from WireService into something
else say WireServiceComponent (both in the wire and the component off
course) the test will fail.
I have debugged the source and found that one can fix the problem by
modifying the method:
org.apache.tuscany.sca.assembly.builder.impl.CompositeWireBuilderImpl.co
nnectWires( ....)
It contains the following line:
resolvedReference.getTargets().add(resolvedService);
Which should be changed into:
resolvedReference.getTargets().add(target);
This fixes the problem.
However, I am not sure if this is the correct fix. The code preceding
this line is al little strange:
// Resolve the target service
ComponentService target = wire.getTarget();
if (target != null && target.isUnresolved()) {
resolvedService =
componentServices.get(target.getName());
if (resolvedService != null) {
wire.setTarget(target);
The last line doesn't really do anything usefull. So maybe my fix is
part of a bigger problem in the code ...
