Two JBoss 3.2.5 Instances

asamir May 19, 2008 2:40 AM

Hello everybody,

I am trying to run two instances of JBoss 3.2.5 application server on a single machine.
I have done the configuration for the "Service Binding" as per the JBoss documentation (Chapter 10).

However, on a test machine, the second instance does not start. It shows an error message "*** Socket error: Port 0 is already in use. ***" very early in the beginning.

Any hint on the reason of such error ?

Regards,
Samir

Thanks for the link.

I have followed the instruction given in the link. However, it does not work. It still shows the error message "*** Socket error: Port 0 is already in use. ***".

I have also tried to start the second JBoss instance with -b option (different IP address on the same NIC). But still it gives the same error.

I am wondering what could be the reason for that error ?

Samir

What exactly did you change? Can you post the changes in the configuration files? Port 0 is not a port which JBoss uses in any of its port configurations.

While posting the logs or xml content or code, remember to wrap it in a code block using the Code button in the message editor window and please hit the Preview button to make sure your post is correctly formatted

Also, 1.4.1 is a very old JDK. Could you upgrade to the latest 1.4.2 JDK and try again. There might be an incompatibility between 1.4.1 and Windows Server 2003.

I would like to thank all of you for your help and support.

Now it works fine. The problem seemed to be related to Oracle jvm options. The "run.bat" file was configured with debugging options.

Thanks again.
