JNDI look up in two different ways? whats the difference, ad

[subrata_jboss]

while sending message to queue by http

we can populate context in two different ways?
1) Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
p.put(Context.URL_PKG_PREFIXES,
"org.jboss.naming:org.jnp.interfaces");
p.put(Context.PROVIDER_URL, "jnp://192.168.114.116:1099");
ctx = new InitialContext(p);

2) Properties p = new Properties();
p.setProperty(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.HttpNamingContextFactory");
env.setProperty(Context.PROVIDER_URL, ""http://192.168.114.116:8080/invoker/JNDIFactory");

ctx = new InitialContext(p);


How does it matter ????

With (1), access to JNDI service is done by socket/JRMP based protocol of JBoss.

With (2), it is done by HTTP.
