Pedro, There are two issues here that might be causing your problems. One is that many EJB servers including JBoss select random ports for the RMI server with the default configuration. You need to configure the Port and RmiPort properties of the NamingService MBean in JBoss. You'll also need to specify the RMIObjectPort for each container invoker. Then open those ports through your firewall.
It also appears that you're using network address translation (NAT) since you're using private addresses. The RMI implementation supplied by sun doesn't work through NAT. The problem is that the client proxy supplied for remote objects attempts to connect to the server using the server's actual private address instead of the public NAT assigned one. So accessing an RMI server in a NAT network from outside the network will not work unless you modify the address used by the client proxies. The simpliest way to accomplish this is to create you're own ClientSocketFactory class and have it create sockets using the server's public address. Then configure the RMI server with this custom ClientSocketFactory. That's not the most elegant solution. You might look into RMI Proxy, www.rmiproxy.com, or the source code of JBoss for a more elegant solution. --Victor Pedro Salazar wrote:
Greetings, I have a EJB which when it is deployed on my J2EE application server (JBOSS) in my localhost or another host in my local network (e.g. 10.0.0.0/8), it works just fine. But, when I deployed in a host in another network (192.168.89.0/24) which I can pass through it but they can't see me (firewall), if I try to access to my EJB from a client, I get NULL on the return of lookup()!! I would like to know if JNDI lookup is bidirectional, or if the callbacks on EJBs make TCP SYNC connections to my client (which is not possible due the firewall), or if there is any issue here that I don't see because I'm not aware of the JNDI protocol or RMI callbacks of EJB! For example, I can make a JDBC/NET8(oracle)/telnet/ssh to several hosts on the other network but I just can't access to my EJB through JNDI!! thanks, Pedro Salazar -- <id name="pedro salazar"> <email>[EMAIL PROTECTED]</email> <pgp-key-id>0E129E31D803BC61</pgp-key-id> </id>
