How to change rmiPort in JBoss 4.0

[yulinxp]

I'm using JBoss- 4.0.3SP1. I have the error when starting JBoss:
java.rmi.server.ExportException: Port already in use: 1098; nested exception is:

I want to change rmiPort. I found two xml containing "rmiPort":
naming-service.xml in server/default/deploy
NamingService-xmbean.xml in server/default/conf/xmdesc

Then I change RmiPort in naming-service.xml to a different port other than 1098. But when I start the JBoss, it gives me:

12:58:20,839 INFO [NamingService] Started jndi bootstrap jnpPort=1099, rmiPort=1098, backlog=50, bindAddress=/0.0.0.0, Client SocketFactory=null, Ser

org.jboss.deployment.DeploymentException: Trying to install an already registered mbean: jboss:service=Naming

As you can see, the rmiPort is set to 1098 before processing naming-service.xml.
Where is it set? How can I change the port?

Make a serach for "1098" above directory server/default/conf. Its an xml, I'm not sure about the correct name. jboss-service.xml, or something like that.

I also was with this problem. The MSN Messenger was using the port 1098. I changed Jboss Rmi port to 1122, and no more problems about it has occured.
