Java – use local EJBs in the same container but different ears

I'm trying to use local EJBs in the same GlassFish, but different ears But GlassFish cannot find the local EJB or use it

I saw this: according to the Java EE tutorial, the client of @ local bean must run in the same JVM as the enterprise bean it accesses

In the first ear, I have a local interface in jar

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

In another jar, I have an 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 a local interface in jar

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

In another jar, I have consumers

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

When using @ EJB and (name = "mylocalbeanimpl") parameters, 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|#]

Using @ EJB and (name = "my. Package. Mylocalbeanimpl") parameters, the error is:

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

I also try to use mappedname

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

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

But the error still exists

Cannot resolve reference Local ejb-ref name=MyLocalBeanImpl,mappedName=MyLocalBeanImpl,refType=Session

GlassFish works like JNDI

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){......

When I deployed GlassFish, I said JNDI was 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

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

It seems that GlassFish found the local bean, but... GlassFish encountered a problem running such a thing

javax.naming.NamingException

 Can not set my.package.MyLocalBean field my.package.BeanConsumer.beanlocal 
 to   my.package.beans.__EJB31_Generated__MyLocalBeanImpl__Intf____Bean__

And try

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

Oh, I see:

throws javax.naming.NamingException
 javax.ejb.EJBException: javax.ejb.EJBException: javax.ejb.CreateException: Could not create stateless EJB

Solution

You can inject a local EJB into another EJB in the same JVM, but the differences are different

The problem is that you can no longer rely on the bean name because you need to tell the consumer the full JNDI name of the bean You can find this name in the server log during deployment; When the bean is bound to the JNDI directory, the server displays it in the log
