Question

Is it possible to inject EJB 3.1 beans into POJO using CDI on Glassfish v3?

My classes (in EJB module):

@Singleton
@LocalBean
@Startup
@Named
public class NewSingletonBean {

    @PostConstruct
    public void init(){
        System.out.println("NewSingletonBean INIT");
    }

}

_

@Singleton
@LocalBean
@Startup
@DependsOn(value="NewSingletonBean")
public class NewSingletonBean2 {

    @Inject NewSingletonBean newSingletonBean;

    @PostConstruct
    public void init(){
        System.out.println("NewSingletonBean2 INIT");
        System.out.println("EJB injected into EJB: " + (newSingletonBean != null));
        MyPOJO p = new MyPOJO();
        p.sth();
    }

}

_

public class MyPOJO {
        @Inject NewSingletonBean newSingletonBean;

        public void sth(){
            System.out.println("EJB injected into POJO: " + (newSingletonBean != null));
        }
}

Note lines:

INFO: EJB injected into POJO: false

So it looks like @Inject into EJB works fine, but into POJO doesn’t. What am I doing wrong?
I’ve tried on GlassFish 3.1 and 3.0.1 (with NetBeans 7.0.1).

EDIT:
I’m using NetBeans 7.0.1.

Answer 1

I’m not very familiar with CDI but I guess if you’re creating the POJO object yourself, no injection will happen. Did you try:

@Inject
private MyPOJO p;

Instead of:

MyPOJO p = new MyPOJO();  

?
