Remote JNDI/EJB Problems

[Chris]

How's everyone doing today.. Good.

well my problem is driving me crazy, so I hope someone can help me
figure out why this is doing what it's doing.. i'm probably just doing
something "stupid"

I'm trying to call a remote stateless session bean from a different
physical box.

what i have working: i have a ear file w/ the war + ejb.jar all
enclosed and that is working beautifully. now i'm trying to
distribute out the processes. have a "client" either tomcat or a java
application sitting on one box, and the ejb container w/ my session
facades on the other box.

my environment: jboss 3.2.2-tomcat 4.1.24 bundle, linux redhat.

I've been monkeying around with the configuration and have gotten two
different errors.

1st error: java application (see source below) on box one trying to
connect to box 2 jndi but saying connection refused to 127.0.0.1. I
have also even removed (commented out) the localhost references to
/etc/hosts.

this is trying to do a simple listBindings.

java source:

import javax.naming.*;
import java.util.*;
import javax.rmi.PortableRemoteObject;

public class TestClient3 {

public static void main(String[] args){
try{

String sInitialContextFactory =
"org.jnp.interfaces.NamingContextFactory";
String sProviderUrl = "jnp://192.168.0.100:1099";
String sFactoryUrl = "java.naming.factory.url.pkgs";
// also tried sInterface org.jboss.namingrg.jnp.interface
String sInterface = "org.jboss.naming.clientrg.jnp.interfaces";

Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, sInitialContextFactory);
env.put(Context.PROVIDER_URL, sProviderUrl);
env.put(sFactoryUrl, sInterface);


InitialContext initialContext = new InitialContext(env);
System.out.println(initialContext.getEnvironment().toString());
NamingEnumeration enum = initialContext.listBindings("");
System.out.println(enum.toString());

while (enum.hasMoreElements()) {
System.out.println(enum.next().toString());
}
}catch(Exception e){ e.printStackTrace(System.err);
}
}
}

// my box ip i'm running this from is 192.168.0.194 and here's the
output results:

{java.naming.provider.url=192.168.0.100:1099,

Any Ideas?


Problem two. I got the jndi connecting properly but when i try to a
lookup w/ the same string name i'm using through jndi on the bundled
process it's coming up w/

javax.naming.CommunicationException [Root exception is
java.rmi.NoSuchObjectException: no such object in table]

source:
public static void main(String args[]){

try{

String sInitialContextFactory =
"org.jnp.interfaces.NamingContextFactory";
String sProviderUrl = "jnp://zodiac:1099";
// zodiac is 192.168.0.100
String sFactoryUrl = "java.naming.factory.url.pkgs";
String sInterface = "org.jboss.namingrg.jnp.interfaces";


Hashtable env = new Hashtable();

env.put(Context.INITIAL_CONTEXT_FACTORY, sInitialContextFactory);
env.put(Context.PROVIDER_URL, sProviderUrl);
env.put(sFactoryUrl, sInterface);


InitialContext ctx = new InitialContext(env);

Object jndi = ctx.lookup("zodiac_facade/BusinessService");
Object portable = PortableRemoteObject.narrow(jndi,
getEJBClassRef(nServiceId));

}catch(Exception e){ e.printStackTrace(System.err);
}
}



and the jndi lookup string works inside the web container on the same
box... I even got it working through the client application on the
same box.... apparently the problem is just when it's on a remote box.
there is no firewall i've turned off /etc/init.d/iptables.sh stop

i'm baffled,

someone please give me some pointers.
