JBoss - ExportException: Port already in use: 1098

Question

Hello,

I'm getting the following error when I try to start JBoss

10:10:43,298 INFO  [WebService] Using RMI server codebase: http://127.0.0.1:8083/
10:10:43,938 ERROR [AbstractKernelController] Error installing to Start: name=jboss:service=Naming state=Create mode=Manual requiredState=Installed

However When I try to see what ports are being listened to. I don't see that port!

any ideas?

Answer 1

We ran into this problem some time ago as well, not just with JBoss, but also MySQL. I wrote about it in more detail here:

Windows TCP Port Conflicts above 1024

What it comes down to is that Windows uses the port range between 1000 and 5000 for so called "ephemeral" ports. This means that it assigns ports from this range for processes that request a random port.

On Windows 2000/2003 Server installations as well as on Windows XP Pro you can reserve port ranges (even if they only cover a single port) for your applications. Effectively they are not reserved for anything specific, but just excluded from the dynamic allocation. To do so, create or edit the following registry value (type REG_MULTI_SZ/Multi-String Value):

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\ReservedPorts

In this value specify port ranges in the format xxxx-yyyy with xxxx and yyyy being the lowest and highest port of the range to be reserved. To reserve a single port, just use the same values for both (e. g. 1099).

Answer 2

Try TCPView (http://technet.microsoft.com/en-us/sysinternals/bb897437.aspx). I get this "port already in use" quite a lot, and TCPView always usually catches the culprit.

Answer 3

I guess that port is still in use. You can find that using:

netstat -ao

and

netstat -b

If you can't use that port, find another port and change it in the following XML file:

conf/bindings-beans/META-INF/bindings-jboss-beans.xml

The JBoss 5 has a new ServiceBindingManager which uses bean injection to assign ports at runtime. Changing the port here may do the trick for you. You can also use a different ports configuration and override the ports by a factor.
