今天刚学ejb，Jboss也安装成功了，可输入localhost：8080什么都没有，我记得tomat当时没有用8080端口，应该不是tomcat的原因，网上下了个察看端口占用情况的软件，发现是被oracle占了，修改Jboss的默认端口。到jboss-4.2.3.GA/server/default/deploy/jboss-web.deployer下，打开server.xml，修改默认的8080端口为8081之类的就可以了。
JBOSS默认的各种设置文件中通常定义了以下几个端口:
The ports found in the default configuration Port Type Service
。1099 TCP org.jboss.naming.NamingService
。1098 TCP org.jboss.naming.NamingService

。0a TCP org.jboss.mq.il.rmi.RMIServerILService
。0b UDP org.jboss.jmx.adaptor.snmp.agent.SnmpAgentService
a, This service binds to an anonymous TCP port and does not support configuration of the port or bind interface currently(3.2.2).
b, This service binds to an anonymous UDP port and does not support configuration of the port or bind interface.(3.2.2).
