Error con Initial Context

Question

I was running the example that this in the tutorial but I am having problems.
The code is:
public static void main(String[] args) {
          String name = "autoexec.bat";
          Hashtable env = new Hashtable();
          env.put(Context.INITIAL_CONTEXT_FACTORY,
               "com.sun.jndi.ldap.LdapCtxFactory");
          try {
               // Create the initial context
               Context ctx = new InitialContext(env);
               // Look up an object
               Object obj = ctx.lookup(name);
               // Print it
               System.out.println(name + " is bound to: " + obj);
          } catch (NamingException e) {
               System.err.println("Problem looking up " + name + ": " + e);
And the error is:
Problem looking up autoexec.bat: javax.naming.CommunicationException: localhost:389 [Root exception is java.net.ConnectException: Connection refused: connect]

Answer 1

you are trying to connect to an LDAP directory server, but obviously there is no such server running on your machine.
If you want to work with LdapCtxFactory, you need an LDAP server, e.g. openldap, which is included in most LINUX distributions (see also www.openldap.org).
