      Add @Resources to the EJB Bean to have it bind the expected location of the @EJB(mappedName=...)

      @Resources( {
    @Resource(name="java:/MappedHelloBean", lookup="java:global/mapped-name/HelloBean!com.jboss.examples.ejb.Hello"),
})
@Stateless(name="HelloBean", mappedName="MappedHelloBean")
@Remote(Hello.class)
public class HelloBean implements Hello {

      Or use @Stateless(name=...) and @EJB(name=...)
      Or use @EJB(lookup=... and one the portable JNDI bindings which are defined by EE6+ Or use @Resources on the EJB to create a custom JNDI binding and use @EJB(lookup or @EJB(mappedName=... to lookup the custom binding.

      Note as mappedName is not portable, it is recommended to use name or use lookup and one of the EE6+ portable JNDI bindings.

      EJB Bean with mappedName is not binding , the mappedName is vendor specific, it is not portable, however @EJB(mappedName=...) is expecting a global JNDI path, but @Stateless(mappedName=...) does not appear to be binding anything.

      @Stateless(name="HelloBean", mappedName="MappedHelloBean")
public class HelloBean implements Hello {
...

      @Startup
@Singleton
public class TestSingleton {
  @EJB(mappedName="MappedHelloBean")
  private Hello ejb;
...

      So the @EJB causes the TestSingleton to fail.
