I am still having some issues integrating the additional contributions

I think the definitions are still not good as I get the errors on mvn 
jetty:run

As I mention below mvn install both work fine.
The war is also enclosed.

Thank you.

Below follows the issues:

The Web-App composite: qmAppSCA01.composite has a:

        <reference name="QueryController" 
target="QueryControllerComponent/QueryController">


as in:

    <component name="QueryServiceComponent">
        <implementation.java class="org.rd.qm.impl.QueryServiceImpl"/>
        <service name="QueryService">
<interface.java interface="org.rd.qm.QueryService" />
        </service>

        <reference name="QueryController" 
target="QueryControllerComponent/QueryController">

         <interface.java interface="org.rd.qm.QueryController" />
        </reference>
    </component>
----------------------

The QueryController composite: qmController.composite declares the 
service as: 


    <component name="QueryControllerComponent">
        <implementation.java class="org.rd.qm.impl.QueryControllerImpl"/>
        <service name="QueryController">
            <interface.java interface="org.rd.qm.QueryController"/>
        </service>
    </component>


where the QueryControllerImpl class implements the QueryController 
service from QueryController interface as: 


import org.oasisopen.sca.annotation.Service;
import org.rd.qm.QueryController;

@Service(QueryController.class)
public class QueryControllerImpl implements QueryController {... }
----------------------

mvn package / install all work fine.
On mvn jetty:run I get the error:

I have similar issues going from the qmController->QueryExecutor to the 
domainBCA objects: Person and PhysicalLocation.


For example:

The QueryController composite: qmController.composite declares the 
QueryExecutor service as: 


    <component name="QueryExecutorComponent">
        <implementation.java class="org.rd.qm.impl.QueryExecutorImpl"/>
        <service name="QueryExecutor">
            <interface.java interface="org.rd.qm.QueryExecutor" />
        </service>
        <reference name="Person" target="PatientComponent/Person">
            <interface.java interface="com.bca.pearl.domain.Person"/>
        </reference>
    </component>
----------------------
and domainBCA composite declares PatientComponent as:

    <component name="PatientComponent">
        <implementation.java class="com.bca.pearl.domain.impl.PatientImpl"/>
        <service name="Person">
            <interface.java interface="com.bca.pearl.domain.Person" />
        </service>
    </component>
----------------------

I get same errors at QueryExecutor <> Person. I am not understanding 
where i am missing it.



I have tried taking out the service references and just deploying all 
the composites into the sca-contributions folder and starting jetty and 
jetty starts fine.



So just wondering also why mvn install passes if component definitions 
are not correct.



Of course I am not at accessing them yet - but I am thinking once past 
this hurdle I should be good? ;-).


Thanks again.

It looks like you're using the wrong reference name in your component
definitions.  The correct name is queryController, not QueryController.
