I tried both the %JAVA_HOME%/lib and %JAVA_HOME$/jre/lib/ext with the jar
you suggested. I downloaded and unzipped all the jars I could find and
tried running the program with the jars installed in both directories and I
had no success.

Here's the code:

try
{
  String name=args[0];
  Hashtable env = new Hashtable();
  env.put(Context.INITIAL_CONTEXT_FACTORY,
      "com.sun.jndi.fscontext.RefFSContextFactory");

  Context ctx = new InitialContext(env);
  Object obj = ctx.lookup(name);
     System.out.println(name + " is bound to: " + obj);
}
catch (Exception e)
{
  e.printStackTrace();
}

I'm using for the local file system so their are no other links. The
exception is:

javax.naming.NoInitialContextException: Cannot instantiate class:
com.sun.jndi.f
scontext.RefFSContextFactory [Root exception is
java.lang.ClassNotFoundException

Patrick, you need RefFSContextFactory in your classpath.

Go to the link below and download JNDI support zip that contains jars and
classes that you need.

http://java.sun.com/products/jndi/downloads/index.html#DOWNLOAD12

Unzip fscontext.jar (and providerutil.jar too I think) (the only jars in
the zip) to JRE_HOME\lib\ext and it will be in your classpath next time
you go to runtime. The class cited in your exception is in the
fscontext.jar.

Good luck. You should be able to do file name lookups after fixing that.
