Simon,
I believe I am very close to what I need - thanks to you. Here is where
I am at:
SCANode2Factory nodeFactory = SCANode2Factory.newInstance();
SCANode2Factory.SCAContribution[] contributions = new
SCANode2Factory.SCAContribution[0];
SCANode2 node =
nodeFactory.createSCANode(urlComposite.toURI().toString(),
sCompositeContents, contributions);
I am getting some output like:
Apr 28, 2008 2:49:40 PM org.apache.tuscany.sca.node.impl.NodeImpl <init>
INFO: Creating node:
http://localhost:7001/crms-domain/metadata/transformation.service/consum

Hi Daniel
Good question. The OASIS TC has proposed a solution to this issue (
http://www.osoa.org/jira/browse/JAVA-9) but this isn't part of the API
we have implemented as we have taken the V1 API. Can you raise a JIRA
for this as I can't see one already and at least in that way we can
track it.
Is it possible for you to inject the references you need. You can
specify a reference with multiplicity as a collection, for example, from
itest/references
@Reference(name = "dServiceReferences")
public List<ServiceReference<DComponent>> dServiceReferences;
Which is populated by
<component name="AComponent">
...
<reference name="dServiceReferences" target="DComponent
DComponent1"
/>
</component>
<component name="DComponent">
<implementation.java
class="org.apache.tuscany.sca.itest.references.DComponentImpl" />
</component>
<component name="DComponent1">
<implementation.java
class="org.apache.tuscany.sca.itest.references.DComponentImpl" />
</component>
See the test for alternatives.
Regards
Simon
