If you want to assign a custom global JNDI name to your EJB, you can use:
@Stateless(mappedName="ejb/Foo")
public class EchoProviderBean implements EchoProviderLocal {
See its javadoc:
http://java.sun.com/javaee/5/docs/api/javax/ejb/Stateless.html
Note that mappedName is not portable (see the above javadoc for more
details). It's supported in glassfish but may not work in other appserver.
Oftentimes you don't need to worry about an EJB's global JNDI name.
Glassfish assigns default global JNDI name for EJBs according to the
following rules:
https://glassfish.dev.java.net/javaee5/ejb/EJB_FAQ.html#SessionBeanGlobalJNDINameAssignment
If in your sample app, there is only 1 EJB implementing
EchoProviderLocal interface, you can just do the following to get the
bean reference (no xml descriptor, no JNDI lookup):
//inside servlet class
@EJB private EchoProviderLocal echo;
