The javadoc of @Resource#name states that "The JNDI name of the resource. For field annotations, the default is the field name. ..."

The following version 1 of DaServiceBean don't work as it doesn't inject anything to "myVar". The version 2 injects the value 5 correctly.

— Version 1 —
@Stateless
@Remote
@RemoteBinding(jndiBinding="daService")
public class DaServiceBean implements DaService {
@Resource private int myVar;
public void foo()

{ System.out.println("myVar: " + myVar); }

}

— Version 2 —
@Stateless
@Remote
@RemoteBinding(jndiBinding="daService")
public class DaServiceBean implements DaService {
@Resource(name="myVar") private int myVar;
public void foo()

{ System.out.println("myVar: " + myVar); }

}
