Weblogic12c deployment EJB ambiguous error

Question

I'm trying to deploy the application in Weblogic 12c. During deployment, I'm getting the below error

weblogic.management.DeploymentException: weblogic.application.naming.ReferenceResolutionException: [J2EE:160092]Error: The ejb-link "BeanClass" declared in the ejb-ref or ejb-local-ref "...BeanClassService/beanClass" in the module "....EJB.jar" is ambiguous. Qualify this ejb-link to remove the ambiguity.

Code:

IBeanClass.java

@Local

public interface IBeanClass {}

BeanClass.java

@Stateless(name = "BeanClass")

@PermitAll

public class BeanClass implements IBeanClass { ...... }

IBeanClassService.java

@Local

public interface IBeanClassService { ......... }

BeanClassService.java

@Stateless(name = "BeanClassService")

public class BeanClassService implements IBeanClassService {

@EJB(beanName = "BeanClass")

private IBeanClassService beanclass;

... }

I'm making a call to the EJB from the web application project:

ClientClass.java

public class ClientClass{ ....

@EJB(beanName = "BeanClassService")

private IBeanClassService beanclass;

..... }

The code was working fine in weblogic10 but now in weblogic 12 exception occurs. Please help in resolving this issue.

BeanClass is not an IBeanClassService, so even by basic java convention, you cannot assign a IBeanClass object to that variable there, let alone inject an EJB into that spot. What you should have is

  @EJB(beanName = "BeanClass")

  private IBeanClass beanclass;
