By looking at the web.composite file you have:
<composite xmlns="http://docs.oasis-open.org/ns/opencsa/sca/200903";
xmlns:tuscany="http://tuscany.apache.org/xmlns/sca/1.1";
targetNamespace="http://com.bca.app";
name="qmApp">
<!-- component name="qmAppWebComponent">
<implementation.web web-uri=""/>
<reference name="service" target="QueryServiceComponent"/>
</component>
<component name="QueryControllerComponent">
<implementation.java class="com.bca.qm.QueryControllerImpl"/-->
</component>
<component name="QueryService">
<implementation.java class="com.bca.pearl.app.QueryServiceImpl"/>
</component>
</composite>
There are two issues:
1) The target attribute doesn't match the component name (red)
2) There is no reference under QueryService component to
QueryControllerComponent
Thanks,
Raymond
