How to change the port number 8080 in /seam-sp/MetaDataService.seam

Version 1

    Installed the seam example seam-sp.war from picketlink 1.0.2 and put it into jboss server 5.0.1 running at port 80. When I typed the URL

    http://localhost:80/seam-sp/MetaDataService.seam. Inside of the meta data service xml, the port is always 8080. How do I change the port number?
