    remote JNDI lookup fails

      Hi,

      I've a problem reaching JDNI from a remote, standalone client. The lookup is done by the following code:

      Properties props = new Properties();
      props.setProperty("java.naming.provider.url", "jnp://server:1099");
      props.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming");
      props.setProperty("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
       InitialContext ctx = new InitialContext(props);
      result = ctx.lookup(path);


      It runs perfect on the host "server". But when I run it on a different host, I get an exception:
      javax.naming.CommunicationException [Root exception is java.rmi.ConnectException: Connection refused to host: 127.0.0.1; nested exception is:
       java.net.ConnectException: Connection refused]

      What surprises me is, that the client seems to try to connect to localhost, even though the provider URL points to a different host.

      There are no firewalls between the two maschines. JBoss (4.2.2GA) is listening on the respective IP/port on the server, I can reach it with telnet.

      If I shutdown JBoss, I get a different error message. Therefore I assume, that the client is connecting to the server.

      Thanks in advance,
