I have an application that runs on Jboss 3.2.3 (W2K and RH), with a client application
needing to do a lookup to grab a session bean. Everything works fine as long as the
client is on the same machine as the server. As soon as I try to do the JNDI lookup on
a remote server, the JNDI directory appears to be empty to the client.
I then wrote a test class that does a listBindings() on the InitialContext. Whenever I
try to list bindings for the context that I know exists, it'll give the following
error:
javax.naming.CommunicationException. Root exception is
java.rmi.NoSuchObjectException: no such object in table

public class Test {
public static void main(String[] args) {
try {
Hashtable contextProperties = new Hashtable();
contextProperties.put("java.naming.factory.initial",
"org.jnp.interfaces.NamingContextFactory");
contextProperties.put("java.naming.factory.url.pkgs",
"org.jboss.naming:org.jnp.interfaces");
contextProperties.put("java.naming.provider.url",
"jnp://nolan.radius:8099");
InitialContext initialContext = new InitialContext(contextProperties);
System.out.println(initialContext.getEnvironment().toString());
NamingEnumeration enum = initialContext.listBindings("buildman/ejb");
System.out.println(enum.toString());
while (enum.hasMoreElements()) {
System.out.println(enum.next().toString());
}
}
catch (NamingException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
}
}
If I do try it with "java:" instead, I get back an empty
org.jnp.interfaces.NamingEnumerationImpl
I also set the bind address for jboss to the IP address of the box. When I telnet to
the IP and the port I run JNDI on (8099), I get garbage back with the RMI url being
the correct IP address.
Any ideas?
