I am having difficulty figuring out why my spring bean is not getting injected

I am having difficulty figuring out why my spring bean is not getting injected into my CXF web service that is being deployed into jboss.
Here is the scenario:

I have multiple Service classes which implement an Interface

Here is Implementation # 1

@Service("retrieveService")
@Scope("prototype")
@Transactional(propagation=Propagation.REQUIRED)
public class RetrieveService extends BaseService implements IEuclidService 
{
    @Resource
    private EntrLoanRepository entrLoanRepository;


    @Override
    public RetrieveResponse serve(RequestMessage request) 
    {
                    entrLoanRepository.findByEntrLoanId();
    }
}

Here is Implementation # 2

@Service("disableService")
@Scope("prototype")
@Transactional(propagation=Propagation.REQUIRED)
public class DisableService extends BaseService implements IEuclidService 
{
    @Resource
    private EntrLoanRepository entrLoanRepository;

    @Override
    public RetrieveResponse serve(RequestMessage request) 
    {
                EntrLoan entrLoan = new EntrLoan();
                entrLoan.setEndDate( new Date());
                entrLoanRepository.save(entrLoan);
    }
}

I have my cxf web service, into which I am expecting a spring (service) bean to be injected.

@javax.jws.WebService
public class Euclid implements IEuclid {

    private IEuclidService euclidService

    public MyResponse myMethod(MyRequest req)
    {
    <!-- How do I inject an instance of RetrieveService here ???-->
    euclidService.serve();
    }
}

I tried doing this:

euclidService = ctx.getBean("retrieveService", RetrieveService.class);

but I am getting the error message:

     com.sgb.euclid.contracts.RetrieveEnterpriseLnIdRequest@31d908
     ***1 EuclidService is NULL
     *****Instantiating Spring Bean

I do not quite understand what “type [$Proxy98]” is. I searched in the logs, but cannot see where it is coming from. I assume this is related to spring??
Eitherway, what am I doing wrong that I am unable to instantiate a spring bean keeping in mind that the beans are not defined in beans.xml, but rather annotated.

I feel I am missing something, but cannot quite put my finger on it.

As I am deploying on jboss, the configuration xmls are a bit different that the examples I am seeing online.
Here is my jboss-cxf.xml:

    <jaxws:endpoint id="POJOEndpoint" 
        implementor="com.sgb.euclid.ws.web.Euclid"
        wsdlLocation="WEB-INF/wsdl/EnterpriseLoanIdentifier.wsdl" 
        address="http://localhost:8080/euclid-ws">
        <jaxws:properties>
            <entry key="schema-validation-enabled" value="true" />
        </jaxws:properties>
        <jaxws:invoker>
            <bean class="org.jboss.wsf.stack.cxf.InvokerJSE" />
        </jaxws:invoker>
    </jaxws:endpoint>

And here is the applicationContext-ws.xml:

    <import resource="applicationContext-core.xml" />
    <import resource="applicationContext-jpa.xml" />

    <!-- setting up packages to scan for components -->
    <context:component-scan base-package="com.sgb.euclid.ws.service" />

    <tx:annotation-driven 
    transaction-manager="transactionManager" />

Here is the corresponding web.xml

<!--  setting up spring configuration to instantiate the spring container  -->
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath*:META-INF/spring/applicationContext-ws.xml</param-value>
</context-param>

<servlet>
    <servlet-name>euclid</servlet-name>
    <servlet-class>com.sgb.euclid.ws.web.Euclid</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>euclid</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>

I cannot figure out what my mistake is. Any help is appreciated….

The solution seems to be as follows:

euclidService = ctx.getBean("retrieveService", IEuclidService .class);

or

euclidService = (IEuclidService) ctx.getBean("retrieveService");

It appears that the getBean can only cast to the interface and not the implementation class. … based on http://forum.springsource.org/showthread.php?71543-Proxy-Type-Conversion-Error

Another explanation is here:
Abstract DAO pattern and Spring's "Proxy cannot be cast to …" problem!
