Urgent : Unable to create VALID Initial Context

Question

Hello All,
I am trying to learn JNDI and am using file system service provider which is provided by the sun
I have created the setup directories, but it would not work if I set up those directories on the drive other than C.
The following lines work for C drive :
Hashtable env = new Hashtable(11);
env.put(Context.INITIAL_CONTEXT_FACTORY,
"com.sun.jndi.fscontext.RefFSContextFactory");
env.put(Context.PROVIDER_URL,
"file:/tmp/tutorial");
try {
// Create the initial context
Context ctx = new InitialContext(env);
// Get listing of context
NamingEnumeration list = ctx.list("awt");
// Go through each item in list
while (list.hasMore()) {
NameClassPair nc = (NameClassPair)list.next);
System.out.println(nc);
// Close the context when we're done
ctx.close();
} catch (NamingException e) {
System.out.println("List failed: " + e);
As you all might have guessed this is code from straight from JNDI tutorial. But How do I specify some directory on drives other than C.
Please help : I tried the follwing
env.put (Context.PROVIDER_URL,
NAME);
In place of NAME above I tried the following
"file:///I:\tmp\tutorial"
"I:\tmp\tutorial"
and other silly combinations
****** awt is a directory under "I:\tmp\tutorial"

I wish It would have been pretty ?
But damn it, it doesn't work
I gave something like this
env.put(Context.PROVIDER_URL, "file:///I:/tmp/tutorial");
and the error come like this
Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/jndi/toolkit/chars/CharacterDecoder

If you have any idea whats happening, I would really appreciate
