Can anyone please provide me this information please..... Sorry for being
persistent!!
I am still not clear why a URLStreamHandlerFactory is required for JNDI!!!
I thought Context.lookup() is what the web-apps will do! Why would the
web-apps want to use a new URL("jndi://...."); Where/why does tomcat have
to use jndi URLs to fetch resources??
Can you please elaborate on "It is because Tomcat uses "jndi://..." for
handling web application resources".
Sriram.
