Difference between jsp:useBean and context.lookup("name")

Hi.

Successfully deployed my first bean :)

Wondering about the difference when using the

<jsp:useBean bla bla >

Tag and:

InitialContext ctx = new InitialContext();
Object obj = ctx.lookup("java:comp/env/ejb/CartHome");
CartHome home = (CartHome)javax.rmi.PortableRemoteObject.narrow(obj,
CartHome.class);

This way of using a bean?

Thanks

Christer

This a pure Java Bean, it instantiates the class (not recommended with
EJB!).

This uses an Enterprise JavaBean correctly via the JNDI reference.
