/**
 * -----------------------------------------------------------------------------
 * This example class shows you how to write a program that looks up an object 
 * whose name is passed in as a command-line argument. It uses a service 
 * provider for the file system (fscontext.jar). Therefore the name that you 
 * supply to the program must be a filename.
 * 
 * We first create an initial context. We indicate that we're using the file 
 * system service provider by setting the environment properties parameter
 * (represented by a Hashtable class) to the InitialContext constructor.
 * 
 *  Context.INITIAL_CONTEXT_FACTORY = com.sun.jndi.fscontext.RefFSContextFactory
 * 
 * This class requires the file system service provider. For example, we will
 * use Sun's implementation (fscontext.jar). Keep in mind that use of this 
 * library will also require the (providerutil.jar) library.
 * 
 * To compile this example:
 * 
 *      % javac JNDIFileSystemDemo1.java
 * 
 * To run the example:
 * 
 *      % java -classpath "$JAVALIB/fscontext.jar:$JAVALIB/providerutil.jar:." JNDIFileSystemDemo1 /temp
 * 
 * @version 1.0
