How to call a non-annotated class from a third party from a @controller annotated class?

[mike darthvader]

In my project I have a controller class. It is marked with @Controller annotation.

     @Controller
     @RequestMapping("/cc")

    public class CRProcessController {

	@Autowired
    private IServiceMapper serviceMapper; //this class has methods that are call classes from a third party jar.
	
	@RequestMapping(value = "/details", method = RequestMethod.GET)
	@ResponseStatus(HttpStatus.OK)
	
	public @ResponseBody String getChangeRequest() throws ACCEGenericException {
	  return serviceMapper.getDetails();         
	}

The ServiceMapper class looks like this:

    @Service
    public class ServiceMapper implements IServiceMapper{

	   private IDataService dataService; //This IDataService interface is from a third party jar. The third party jar has code that is NOT annotated.
	
	   @Override
	   public String getDetails() {
		    String details = getDataService().retrieveDetailString();
            return details;
        }
	    public IDataService getDataService() {
		   return dataService;
	    }
      	public void setDataService(IDataService dataService) {
		    this.dataService = dataService;
	    }
    }

Dispatcher-servlet looks like this:

    <import resource="classpath*:/applicationContext.xml" /> //third party jar's application-context	
    <context:component-scan base-package="com.rest" />

    <bean id="serviceMapper" class="com.rest.mapper.impl.ServiceMapper">
		<property name="dataService">
			<ref bean="dataService" />  //This bean exists in the application-context of the third party jar.
		</property>		
	</bean>

Problem: When <context:component-scan> is present in the dispatcher-servlet - Spring seems to be scanning the classes inside the third party jar as well. Third party jar classes have no annotations at all. It throws an error saying it <b>cant create the beans</b> in the third party.

When I remove the <context:component-scan> totally, an error similar to the one below is thrown:

No mapping found for HTTP request with URI [/MYWS/cc] in DispatcherServlet with name 'mvc-dispatcher'

Does anyone know a possible solution to this? I need to be able to use the third party jar's classes and at the same time use @controller to access the web services.

If you don't want to scan all packages, please mention list of packages so Spring scans those packages.

<context:component-scan
		base-package="com.mycompany.pkg1, com.mycompany.pkg2" />

Spring stopped autowiring of third party jar's classes when I removed the @Service annotation from my ServiceMapper class
