Hi I'm new to Jboss And I have spent days trying to solve this. Please help me!
I would like to configure JBoss 4.0.2 on Redhat linux 9. And I need to call remote EJBs from another PC across the internet. It works fine when I modify /etc/hosts so that my hostname can be resolved to a valid IP address.
i.e. 127.0.0.1 localhost.localdomain localhost xxx.xxx.xxx.xxx myHost.localdomain
where xxx.xxx.xxx.xxx is my valid IP
However my ISP often changes my IP address.
First I started jboss under IP address xxx.xxx.xxx.xxx (/etc/hosts contains xxx.xxx.xxx.xxx) Now if my ip changes from xxx.xxx.xxx.xxx to yyy.yyy.yyy.yyy, Then I run my client to remotely invoke EJB with the following settings:
If I change /etc/hosts's ip to yyy.yyy.yyy.yyy now, I still get the same error.
Does anyone know how to modify the rmi address when jboss is running? Or is there any other ways to get around the problem?
you should use dns names instead of IPs, if they are changing. Furtermore, you should make sure to use the jboss.bind.address. This address (or dns name) will be used by all stubs bound in the naming service.

I setup a DNS server and it works perfectly.
But the client still connects to the old ip address for port 1098!!
For example, my hostname is serverA.domain.com The test procedure: 1. I run the server using: ./run.sh -b serverA.domain.com 2. After server starts up. Ip changed. (e.g. from 220.127.116.11 to 18.104.22.168) 3. I use "nslookup -sil serverA.domain.com" on both my server and client to check if the ip is valid. Both shows 22.214.171.124 4. I run EJB client. 5. On client, netstat -n shows the following: 126.96.36.199:1099 CLOSE_WAIT 188.8.131.52:1098 SYN_SENT
JBoss returns the old IP address to the client not the hostname.
I thought JBoss would bind itself to the hostname only and not the IP address. It seems that it's not.
I'm very frustrated... Are there any JBoss experts here? Please help me. Thanks a lot.
