How to Run Simple JNDI Program

Question

This is the Simple JNDI Lookup.java Program which is provided in sun website...
Program compiles Successfully...
While running i got the error...
java Lookup (What name should i give here)
Appart from this i have one binding file(.bindings)
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import java.util.Hashtable;
import javax.naming.directory.InitialDirContext;
class Lookup {
public static void main(String[] args) {
     // Check that user has supplied name of file to lookup
     if (args.length != 1) {
     System.err.println("usage: java Lookup <filename>");
     System.exit(-1);
     String name = args[0];
     // Identify service provider to use
     Hashtable env = new Hashtable(11);
     env.put(Context.INITIAL_CONTEXT_FACTORY,
     "com.sun.jndi.fscontext.RefFSContextFactory");
     try {
     // Create the initial context
     Context ctx ;
     Lookup lu=new Lookup();
     Thread.currentThread().setContextClassLoader(lu.getClass().getClassLoader());
     ctx = new InitialDirContext(env);
     // Look up an object
     Object obj = ctx.lookup(name);
     // Print it out
     System.out.println(name + " is bound to: " + obj);
     // Close the context when we're done
     ctx.close();
     } catch (NamingException e) {
     System.err.println("Problem looking up " + name + ": " + e);
}

first,u should add fscontext.jar and providerutil.jar in your classpath,when run:java Lookup ,must add arguement like: c:\ or c:\jndi(jndi must be created)
document:
The following JNDI environment properties are relevant to the file system service provider. See the JNDI documentation for a description of how properties are initialized using the environment properties, system properties, applet parameters, and resource files.
java.naming.factory.initial
This environment property is used to select the file system service provider. It's not actually used by the provider itself. It specifies the class name of the initial context factory for the provider. It can have one of two values. The first choice names the class responsible for file system access.
For example:
env.put(Context.INITIAL_CONTEXT_FACTORY,
"com.sun.jndi.fscontext.FSContextFactory");
The second choice names the class--a subclass of FSContextFactory--which adds the ability to lookup and store Java objects in the file system.
For example:
env.put(Context.INITIAL_CONTEXT_FACTORY,
"com.sun.jndi.fscontext.RefFSContextFactory");
This environment property must be set if you are using the file system provider for the initial context. The only exception is if you supply only URLs to the initial context, in which case, you don't need to specify this property. See the Types of Objects and how Objects are Named section for details.
java.naming.provider.url
Specifies the file to be used as the root context. It must be a file URL representing a directory in the file system.
For example:
file:///home/kafka
this URL will cause the provider to use the directory named kafka in the directory home in the root directory as the base context. Performing a list() on the initial context would be equivalent to typing the UNIX command ls in the directory /home/kafka directory. If this property is not set, it defaults to the root of the local file system.
java.naming.factory.state
A colon-separated list of the fully qualified class names of state factory classes used to get an object's state for storing given the object itself. You can use this mechanism to transform an object into forms that the files system service provider supports. The file system service provider supports storing Reference and Referenceable objects. See javax.naming.spi.NamingManager.getStateToBind() for details.
java.naming.factory.object
A colon-separated list of the fully qualified class names of object factory classes for transforming objects read from the file system. You can use this mechanism to transform an object into forms expected by the application. See javax.naming.spi.NamingManager.getObjectInstance() for details.
