JNDI namespace.
For example, the business interface Cart for the CartBean session bean may be obtained using
dependency injection as follows:
@EJB Cart cart;
The Cart business interface could also be looked up using JNDI as shown in the following code segment
using the lookup method provided by the EJBContext interface. In this example, a reference to
the client bean’s SessionContext object is obtained through dependency injection:
@Resource SessionContext ctx;
Cart cart = (Cart)ctx.lookup(“cart”);
In both cases, the syntax used in obtaining the reference to the Cart business interface is independent
