[jboss-user] [JNDI/Naming/Network] - remote JNDI lookup fails

[lamprecht]

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]
  |         at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:780)
  |         at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:627)

  |         at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:667)
  |         ... 4 more

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,

Heiner
