Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
org.exolab.jms.jndi.InitialContextFactory.class.getName() );
env.put(Context.PROVIDER_URL, "rmi://192.168.0.2:1099");

Invoke a sender program, outside of firewall (some computer other than the 2 behind my firewall) which employs the code:

Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
org.exolab.jms.jndi.InitialContextFactory.class.getName() );
env.put(Context.PROVIDER_URL, "rmi://216.195.1.39:1099");

connection refused from rmi host

But note that, when sender program is invoked on 192.168.0.2 (within the firewall), receiver responds to messages from the sender-- as expected.
Also note, that when firewall mapping is disabled, then receiver does not respond to sender-- as
expected.
And clearly when the jms server is down, then the receiver program gives and exception-- as
expected.

So it is a firewall issue of some sort. Any help would be appreciated. Mr. Mathews had a similar
problem. Thanks.

[openjms-developer] rmi port and firewall problems-- proposedsolution still
not working </DIV>Tim, Thank you for the new configuration.
This seems llike a good solution, and external ip and internal ip. 
But, I tried this, and still "host refused" from sender If I place
the receiver machine, outside of a firewall, at ip=216.195.1.39 and sender is on
same cpu at Ip= 216.195.1.39. 
 then sender and receiver code work as
expected. ip=localhost will work as well (as
expected).  I have not been able to test when sender is a distinct public
IP, becasue I need access to one, furthermore my
webserver requires firewall configuration in order to work, which is how
another sender ( /= 216.195.1.39) can access sender
code (via java webstart). So,
what are my options? Run jms outside a firewall?  Thanks for your time. Any help would be appreciated.

 This should have been sent to the
openjms-user list.   You need to use the tcp connector rather than rmi,
and configure the
<TcpConfiguration/> element in openjms.xml.
   E.g   <Connectors>
     <Connector
scheme="tcp">      
<ConnectionFactories>        
<QueueConnectionFactory name="QueueConnectionFactory"
/>        
<TopicConnectionFactory name="TopicConnectionFactory"
/>      
</ConnectionFactories>     </Connector>   </Connectors>
    ...
   <ServerConfiguration
host="216.195.1.39"/>   <TcpConfiguration
internalHost="192.168.0.2"/>   See <A

AM To:
openjms-***@lists.sourceforge.net Subject: [openjms-developer] rmi port and firewall
problems-- inside firewall is OK send/receive I am having difficulty connecting to jms
server from OUTSIDE of firewall. I have 2 computers behind a firewall,
192.168.0.2  acting as receiver and has jms server.
 192.168.0.3  acts sender, for test. (Yes, I double checked
these IP numbers-- they are correct) Note that these IPs are not public to the
internet at large, nor should they be. Netgear firewall, 192.168.0.1,  
maps: incoming request on at 216.195.1.39  on port 1099  to
192.168.0.2 216.195.1.39  is a public ip (mine), and web server works
just fine, to verify ip is valid. The mapping mechanism works just fine,
because a web server (/= jms) runs on 192.168.0.2, works
 as expected. The
web server host is listening on 192.168.0.2:8080.
 openjms.xml  file rmi configuration  
192.168.0.3        port 1099
 From
command line, jms server starts up properly. Invoke and receiver program which employs
the code: Hashtable env = new Hashtable();            
env.put(Context.INITIAL_CONTEXT_FACTORY,            
org.exolab.jms.jndi.InitialContextFactory.class.getName()  );
            
env.put(Context.PROVIDER_URL, "rmi://192.168.0.2:1099");

a sender program, outside of firewall (some computer other than the 2
behind my firewall)  which employs the code:
 Hashtable env = new Hashtable();            
env.put(Context.INITIAL_CONTEXT_FACTORY,

env.put(Context.PROVIDER_URL, "rmi://216.195.1.39:1099");

refused from rmi host But
