Problem resolving references with external targets
--------------------------------------------------
Key: TUSCANY-657
URL: http://issues.apache.org/jira/browse/TUSCANY-657
Project: Tuscany
Issue Type: Bug
Components: Java SCA Core
Affects Versions: Java-Mx
Environment: Java
Reporter: Joel Hawkins
Attachments: retailer_warehouse.scdl
Taken from the DevList thread:
Can anyone point me to an example that uses a Composite Reference? I noticed
that the one in BigBank is commented out.
I'm having trouble testing OSGi support against the latest code. I've got a
sample that looks like this:
<composite xmlns="http://www.osoa.org/xmlns/sca/1.0";
xmlns:osgi="http://tuscany.apache.org/xmlns/osgi/1.0";
name="Retailer_Warehouse">
<service name="RetailerService" target="RetailerComponent">
<interface.java
interface="mypackage.Retailer"/>
<osgi:binding.osgi
service="mypackage.Retailer"/>
<reference>RetailerComponent</reference>
</service>
<reference name="ShipperReference" override="may" multiplicity="0..n">
<interface.java
interface="mypackage.Shipper"/>
<osgi:binding.osgi
service="mypackage.Shipper"
filter="(objectclass=mypackage.Shipper)"
immediate="false"/>
</reference>
<component name="RetailerComponent">
<implementation.java class="mypackage.RetailerComponentImpl/>
<references>
<reference name="warehouse" target="WarehouseComponent"/>
</references>
</component>
<component name="WarehouseComponent">
<implementation.java class="mypackage.WarehouseComponentImpl"/>
<references>
<reference name="shipper">ShipperReference</reference>
</references>
</component>
</composite>
According to the spec, it should be legal for the target of the "shipper"
reference to be a Composite Reference (in this case,
ShipperReference):
"A composite reference is a valid target of a wire. In this case, the name of
the reference is the value set on the wire targeting the reference". (pg 24 of
the v.95 spec).
However, the composite above fails when ConnectorImpl attempts to locate the
target (the parent's children map contains only components and services, no
composite references)
