I am making a small chat application.
Where I m using JMX (MBean), which binds a class to the JNDI and the class's functions inturn invokes EJBs when called by the Java clients residing on same or other networks.
I m having JBOSS server running on a Static IP and Java Clients residing on other netwoks behind a router as nat machines inside LAN.
When the JBOSS server is on the same LAN as the Java Clients everything is running fine. But when the Server is on the static IP and the client behind router then the java Clients are able to call the MBean functions via jnp and get the return values (if any), but the real problem is that the server is not able to push objects or messages to the Java Clients independently (which it is able to do in the LAN environment) . I send the Client's Remote object to the server to keep with itself mapped with username as soon as I get connected to the server.
I have tried to put the code snippet to run the server

"%JAVA%" %JAVA_OPTS% -Djava.rmi.server.hostname=1.2.3.4 -Djava.rmi.server.useLocalHostname=false -Djava.endorsed.dirs=%JBOSS_ENDORSED_DIRS% -classpath "%JBOSS_CLASSPATH%" org.jboss.Main %*

at Java Client side
Java Client extends

UnicastRemoteObject

and after getting the Initial Context LookUps the JNDI name of the MBean and then fires a login function passing its object as parameter to the function which Server keeps with it in a variable the function returns well with the values but when the server fires some values independently to the same client using its reference its not able to do that, it gives exception that it is not able to find the client, citing Client's Local IP which it can never find as that Local IP is not residing in its network but on some other network.
I have tried alot to find some way thrugh it but still unsuccessful, kindly some help me.

I m using the code below to find the Initial context of the server:

prop.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
prop.put(Context.PROVIDER_URL, "jnp://1.2.3.4:1099");
prop.put(Context.URL_PKG_PREFIXES, "org.jboss.namingrg.jnp.interfaces");

The exception it gives when the server tries to fire a message to the client via an exposed Client function using Client reference it has stored with itself :
