Consuming local EJB, in the same Container but different ears

Question

I'm triying to consume a Local EJB in the same Glassfish, but different ears. But Glassfish can't found the local EJB or can't consume

I read this: According to the JavaEE tutorial, the client of a @Local bean "must run in the same JVM as the enterprise bean it accesses."

In the first ear, I have the local Interface inside a jar

@Local
public interface MyLocalBean {
  int getNumber(int num3);
} 

In another jar, I have the implementation

@Stateless
@LocalBean
public class MyLocalBeanImpl implements MyLocalBean,Serializable{
     public MyLocalBeanImpl() {}
     public int getNumber(int num3){......

In the second ear, in the same Glassfish

I have the local Interface inside a jar

@Local
public interface MyLocalBean {
int getNumber(int num3);
 } 

In another jar, I have the consumer

@Stateless
@LocalBean
public class BeanConsumer{
@EJB(name="MyLocalBeanImpl")
private MyLocalBean beanlocal;

with @EJB and (name="MyLocalBeanImpl") parameter the error is:

Cannot resolve reference Local ejb-ref name=MyLocalBeanImpl,Local 3.x 
interface =my.package.MyLocalBean,ejb-link=null,lookup=,
mappedName=,jndi-name=,refType=Session|#]

with @EJB and (name="my.package.MyLocalBeanImpl") parameter the error is:

Cannot resolve reference Local ejb-ref name=my.package.MyLocalBeanImpl,
Local 3.x interface =my.package.MyLocalBean,ejb-link=null,
lookup=,mappedName=,jndi-name=,refType=Session|#]***

I tried too with mappedName

    @Stateless(name="MyLocalBeanImpl",mappedName ="MyLocalBeanImpl")
    public class MyLocalBeanImpl implements MyLocalBean{

@EJB(name="MyLocalBeanImpl",mappedName ="MyLocalBeanImpl")
private MyLocalBean beanlocal;

but the error persist

 Cannot resolve reference Local ejb-ref name=MyLocalBeanImpl,
 Local 3.x interface =my.package.MyLocalBean,ejb-link=null,
 lookup=,mappedName=MyLocalBeanImpl,jndi-name=,refType=Session

GlassFish works with a JNDI like

 java:global[/<app-name>]/<module-name>/<bean-name>

I added the annotation @LocalBean to the bean MyLocalBeanImpl

@Stateless
@LocalBean
public class MyLocalBeanImpl implements MyLocalBean{
     public MyLocalBeanImpl() {}
     public int getNumber(int num3){......

and when I deployed Glassfish say the jndi are two

  Portable JNDI names for EJB OtroBean
  java:global/myfirstear/myejbs/MyLocalBeanImpl!my.package.MyLocalBeanImpl  
  and
  java:global/myfirstear/myejbs/MyLocalBeanImpl!my.package.MyLocalBean

i'm trying with

 @EJB(lookup="java:global/myfirstear/myejbs/MyLocalBeanImpl!my.package.MyLocalBeanImpl")

It seems that Glassfish found the Local Bean, but... Glassfish have problems casting o something like this

 javax.naming.NamingException
 javax.ejb.EJBException: javax.ejb.CreateException: Could not create stateless EJB
 at     
 com.sun.ejb.containers.StatelessSessionContainer

And trying with

 @EJB(lookup="java:global/myfirstear/myejbs/MyLocalBeanImpl")

I get:

The "Local" in "Local EJB" means "local to your application". Either merge the EARs or make it a remote EJB. – Calle

In the Book "EJB3 Developer Guide" says: Note that we have prefixed the interface definition with the @Remote annotation. This indicates to the EJB container that this bean may be invoked by a remote client. By remote, we mean a client that does not reside in the same Java Virtual Machine (JVM) as the container. The good news is that we can dispense with JNDI altogether if the client runs from within an application client container (ACC). – Nephritic

Answer 1

It is possible to inject a local EJB into another EJB in the same JVM but different ear.

The problem is that you cannot rely on the name of the bean anymore as you need to tell the consumer bean the complete JNDI name. You can find this name in the server logs during deployment; the moment the bean is bound to the JNDI directory the server shows it in the logs.

Thanks Gonzalo. GlassFish works with a JNDI like java:global[/<app-name>]/<module-name>/<bean-name> I added the annotation @LocalBean to the bean MyLocalBeanImpl i'm trying with @EJB(lookup="java:global/myfirstear/myejbs/MyLocalBeanImpl!my.package.MyLocalBeanImpl") It seems that Glassfish found the Local Bean, but... – Nephritic

Have you tried just /<app-name>]/<module-name>/<bean-name>? If you can also update the thread question that would be great, it's not easy to read an exception in a comment ;) – Removal
