我使用netbeans IDE 7.4和Glassfish 4.0版。我对这个错误非常恼火，“Glassfish服务器无法启动HTTP并且HTTPS侦听器端口被占用。” 我像这样更改了domain.xml文件凭证
network-listener name="http-listener-1" port="8686" protocol="http-listener-1" thread-pool="http-thread-pool" transport="tcp"/>
network-listener name="http-listener-2" port="8787" protocol="http-listener-2" thread-pool="http-thread-pool" transport="tcp"/>
network-listener name="admin-listener" port="8888" protocol="admin-listener" thread-pool="admin-thread-pool" transport="tcp"/>
问题仍然存在。如何解决这个问题？
