Hi all,
I'm trying to launch an application with the following distributed
architecture/configuration (with two nodes):
**** ComponentA and ComponentActrl on Node_compA:
node_compA.composite :
<composite xmlns="http://www.osoa.org/xmlns/sca/1.0";
targetNamespace="http://sample";
xmlns:sample="http://sample";
name="Node_compA_comp">
<component name="ComponentA">
<implementation.java class="a_comp.A_Impl" />
</component>
<component name="ComponentActrl">
<implementation.java class="a_comp.A_ctrl" />
<reference name="userAtask" target="ComponentA" />
<service name="Tmp_double">
<interface.java interface="aSEQb.Tmp_double"/>
</service>
<service name="ActrlPorts">
<interface.java interface="a_comp.ActrlPorts"/>
</service>
</component>
</composite>
cloud/Node_compA.composite:
<composite xmlns="http://www.osoa.org/xmlns/sca/1.0";
xmlns:t="http://tuscany.apache.org/xmlns/sca/1.0";
targetNamespace="http://sample/cloud";
xmlns:s="http://sample";
name="Node_compA">
<component name="Node_compA">
<t:implementation.node uri="node_compA"
composite="s:Node_compA_comp"/>
<service name="Node">
<binding.sca uri="http://localhost:8200"/>
</service>
</component>
</composite>
**** FakeComponentA on Node_fakeA
node_fakeA.composite:
<composite xmlns="http://www.osoa.org/xmlns/sca/1.0";
targetNamespace="http://sample";
xmlns:sample="http://sample";
name="Node_fakeA_comp">
<component name="FakeComponentA">
<implementation.java class="fake_comp.A_fake_Impl" />
<reference name="fakeUseA" target="ComponentActrl/Tmp_double" />
<reference name="fakeCtrlA" target="ComponentActrl/ActrlPorts" />
</component>
</composite>
cloud/Node_fakeA.composite:
<composite xmlns="http://www.osoa.org/xmlns/sca/1.0";
xmlns:t="http://tuscany.apache.org/xmlns/sca/1.0";
targetNamespace="http://sample/cloud";
xmlns:s="http://sample";
name="Node_fakeA">
<component name="Node_fakeA">
<t:implementation.node uri="node_fakeA"
composite="s:Node_fakeA_comp"/>
<service name="Node">
<binding.sca uri="http://localhost:8100"/>
</service>
</component>
</composite>
--------------------
A client program launches Node_fakeA, get the service
ComponentActrl/Tmp_double. The associated interface is :
@Remotable
public interface Tmp_double {
void set_double(double val);
void set_void();
}
From the client program, the set_double(..) operation is called. It
just make a call of the same operation on ComponentActrl. But at this
point, an error occurs.
Here is the relevant part of the Client program:
public class ApplManagerWithFakeComp {
public static void main(String[] args) throws Exception {
.... // Create a fake_A node
NodeLauncher launcher = NodeLauncher.newInstance();
String configurationURI =
"http://localhost:9990/node-image/Node_fakeA";;
SCANode2 node =
launcher.createNode(configurationURI);
// Start the node
try {
node.getClass().getMethod("start").invoke(node);
} catch (Exception e) {
System.err.println("SCA
fakeCompA_node: could not be started");
throw e;
}
System.out.println("SCA fakeCompA_node started. Test usage");
SCAClient client = (SCAClient)node;
Tmp_double prov_inA = client.getService(Tmp_double.class,
"FakeComponentA/Tmp_double");
if (prov_inA == null){
System.err.println("Error: Getted service is
null!!!!!!!!!!!!!");
}
// Do some computations
System.out.println("test multiple task executions for three
inputs"); System.out.println("set inA = 50");
prov_inA.set_double(50);
/****************/
System.out.println("set inA = 100");
prov_inA.set_double(100);
System.out.println("set inA void");
prov_inA.set_void();
}
}
**************************
To execute the application, I launch the domain manager, Node_compA
(it starts normally) and then the client program. At the line marked
by /****************/ I obtain the following trace-error:

in the trace, I expected a log message saying that an instance of a
ComponentActrl is created when FakeComponentA tries to use one of its
services. But it doesn't seem to be created!? At the same time I don't
understand how the wires of FakeComponentA references to
ComponentActrl services succeed

without an errors like component or reference not found.
Am I wrong somewhere? Let me know if you need any additional
information (code/xml descriptions).
Thank you for your help.
