Hi, The app server cannot bind to that port because it is already in use. If you are using JBoss 4.2.3GA, you can change the port by editing the file located at: server\xxx\deploy\jboss-web.deployer\server.xml Once in there, change the port attribute: <Connector port="8080" address="${jboss.bind.address}" .... Also keep in mind that there may be other binding issues with other ports such as JNDI, etc. So, you'll have to resolve each one individually.
