Hostname problem while starting jboss

[sahidkhn]

The ip/hostname of my machine is set dynamically using a dhcp server. So my hostname changes to something other than localhost. In this scenario, attempt to start JBoss 4.2 fails. But if I change hostname manually to localhost, it works. Is there any work around such that I'll not need to set hostname manually? Please help me regarding this.

Hello,

you can start your JBoss with bin/run.sh --host 0.0.0.0( or extend run.sh about it). The JBoss will be binded to all ip addresses on your computer.

I hope it helps.

Thank you Andreas for your response.

But unfortunately it does not resolve my problem totally. I am using PPPoE for Internet.
If I am not connected to Internet and try to start the JBoss your suggestion works.
But if I try to start JBoss after connecting to Internet same problem occurs. I have to
set the hostname manually for the later.

Any more clue..?

Sahid

What problem? Can you please provide more details about the issue? Which JBoss version (include the minor version of 4.2) and Java version are you using?

[sahidkhn]

I am using jboss-4.2.2.GA and jdk 1.5.0_15-b04.

The problem is jboss boot process fails with the following message

[sahid@unknown001cc051e93b ~]$ /usr/local/jboss/bin/run.sh -c all --host 0.0.0.0

Looks like a problem in the etc/hosts file. Can you post its contents? Also see this http://www.jboss.com/index.html?module=bb&op=viewtopic&t=124173

[sahidkhn]

My /etc/hosts looks like following:

[sahid@unknown001cc051e93b bin]$ cat /etc/hosts
127.0.0.1 localhost localhost.localdomain

But problem is once I starte PPPoE, my hostname changes to something else. And JBoss can not identify this hostname.

[jaikiran]

I work on a Windows system and hence can't test/reproduce anything related to this. Based on what i have seen the posts (that i referred in my earlier reply), JBoss expects the hostname entry to be present/mapped in the /etc/hosts file. So the simplest way to get this working is, every time your hostname changes, you will have to edit the /etc/hosts file to map the IP and the hostname.

[sahidkhn]

Yes I understand that JBoss expects machine's name to be mapped properly in /etc/hosts file.
But unfortunately, I am using DHCP to get ip/hostname of my machine. So there is no way
I can have static /etc/hosts file. Yes as you suggested, each time if I change it manually,
it will work perhaps. But, I was just trying to avoid this pain.

Anyway many thanks for your suggestion though.
