How can I inject an EJB from an other application on the same GlassFish Server?

Question

I have two applications running on my local glassfish server. One to rent bicylces and one to buy train tickets. I now wanted to call a remote ejb from the train application

Answer 1

In your bicycle app you have to:

• remove the @Remote annotation from your interface FahrradRemote
• add the @Remote annotation to your FahrradService EJB

You can follow this snippet:

@Remote(FahrradRemote.class)
@Stateless
public class FahrradService implements FahrradRemote, Serializable {
    .... // your code 
}

(if your are using EJB 3.X, there is no need for an EJB to explicitly implement the SessionBean interface)

In your train app:

@EJB(name="FahrradService") 
private FahrradRemote fahrradService;

(use name attribute instead of mappedName; and you cannot have static properties in a stateless EJB)

Finally you have to tell the container where to lookup for the EJB implementation: create the descriptor glassfish-ejb-jar.xml and, inside glassfish-ejb-jar tags, put this:

  
    BahnPM
    
      FahrradService
      java:global/MyRemoteBeanModule/MyRemoteBean
    
  

The portable JNDI name for your remote EJB (what I have called java:global/MyRemoteBeanModule/MyRemoteBean) is available in GlassFish logs when you deploy the bicycle application.
