how can use @EJB with remote interface"

 

I have glassfish v4 and 2 ears:

  • Service.ear contains EJBs.
  • WebApplications.ear contains Web Applications.

    • I try to use the: 

    @EJB(mappedName="java:global/Service/allServices/ServiceEJBs!Service1Remote")
Service1Remote service1Remot;

    But I got error:

    Caused by: com.sun.faces.spi.InjectionProviderException: com.sun.enterprise.container.common.spi.util.InjectionException: Exception attempting to inject Remote ejb-ref name=java:global/Service/allServices/ServiceEJBs!Service1Remote,Remote 3.x interface =Service1Remote,ejb-link=null,lookup=,mappedName=global/Service/allServices/ServiceEJBs!Service1Remote,jndi-name=,refType=Session into class com.manage.application.WebApplication: null

    But when I user the : 

    Service1Remote remote= (Service1Remote) new InitialContext().lookup("java:global/Service/allServices/ServiceEJBs!Service1Remote");

    it works fine.

    The EJB: 

    @Remote
public interface Service1Remote{
   public long getCount(int itemId);
}

@Stateless(name = "ServiceEJBs" , mappedName ="ServiceEJBs")
public Service1Bean implements Service1Remote{
   public long getCount(int itemId){
     ...............
     return 100000999; 
   }

}

    Clearly your definition for @EJB(mappedname) differs from the mapped name in @Stateless(mappedNamed) definition.

    That said, it wont even work if you replaced the correct mapped name (Cause these are in two different ear deployments).

    to actually get a reference, please use 

    @EJB(lookup="java:global/Service/allServices/ServiceEJBs!Service1Remote")

    Instead of 

    @EJB(mappedName="java:global/Service/allServices/ServiceEJBs!Service1Remote")

    I reinstall the latest versions of glassfish 4.1 and JDK1.8.0_25, and as Maress said changed : 

    @EJB(lookup="java:global/Service/allServices/ServiceEJBs!Service1Remote")

    Instead of 

    @EJB(mappedName="java:global/Service/allServices/ServiceEJBs!Service1Remote")

    and now it's working fine.

    Thanks Maress :)
