How to inject EJB beans with Spring DI.

[sam White]

Hi，

With Spring 3， EJB3，I created a project EAR which consist of a EJB web service consumer layer and a WAR layer.
The WAR layer have to access some APIs that are written in the EJB layer.

During the deployment process, JBOSS AS7 throws the following exception:

The CategoryManagerImpl.java is in EJB layer:

@Stateless
//@LocalBean
public class CategoryManagerImpl implements CategoryManager {
//    @WebServiceRef(wsdlLocation = "META-INF/wsdl/www.ixsystems.com.au/category-ws-0.0.1-SNAPSHOT/services.wsdl")
    @WebServiceRef(wsdlLocation = "http://www.ixsystems.com.au/category-ws-0.0.1-SNAPSHOT/services?wsdl")
    private CategoryWebService_Service service;
    
    private static final Logger logger = Logger.getLogger(CategoryManagerImpl.class);

    @Override
    public Collection<CategorySubcategories> findAll() {
        List<CategorySubcategories> result = new ArrayList<CategorySubcategories>();
        try { // Call Web Service Operation
            ix.houseware.category.service.CategoryWebService port = service.getCategoryWebServiceImplPort();
            result = port.findAll();
            logger.info("Result = " +result.toString());
            System.out.println("Result = "+result);
        } catch (Exception ex) {
            throw new RuntimeException(ex.getMessage());
        }
        return result;
    }
    
    @Override
    public Collection<CategorySubcategories> find(final String name, final String desc) {
        List<CategorySubcategories> result = new ArrayList<CategorySubcategories>();
        try { // Call Web Service Operation
            ix.houseware.category.service.CategoryWebService port = service.getCategoryWebServiceImplPort();
            // TODO initialize WS operation arguments here
            result = port.find(name, desc);
            logger.info("Result = " +result.toString());
        } catch (Exception ex) {
            throw new RuntimeException(ex.getMessage());
        }
        return result;
    }
    
}

The CategoryFinderController.java is in the WAR module:

@Controller
@RequestMapping("/category")
@Transactional
public class CategoryFinderController {
                @EJB
                private final CategoryManager categoryManager;

                @Autowired
                  public CategoryFinderController(CategoryManager categoryManager) {
                       logger.info("calling CategoryFinderController");
                       this.categoryManager = categoryManager;
                  }

Here is my WEB-INF/mvc-dispatcher-servlet.xml in WAR file is shown below:

<beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:context="http://www.springframework.org/schema/context"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="
        http://www.springframework.org/schema/beans     
        http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context-3.0.xsd">

        <context:component-scan base-package="ix.houseware.category.controller" />

        <bean
                class="org.springframework.web.servlet.view.InternalResourceViewResolver">
                <property name="prefix">
                        <value>/WEB-INF/pages/</value>
                </property>
                <property name="suffix">
                        <value>.jsp</value>
                </property>
        </bean>
</beans>

I may be have mis-used Spring DI with EJB in the WAR module, but I could not found what is wrong with the configuration.

Any suggestion is very appreciated.
