java Glass Fish 3连接拒绝Netbeans IDE 8

Question

我正在尝试连接到glassfish服务器，但每次运行预先编写的程序时都会出现此错误。我正确地安装了netbeans和glassfish3，并设置了服务器，所以我没有主意。错误如下。非常感谢

这可能是您的连接端口被占用的问题。尝试更改连接端口号，然后重新连接。找到第四个域名。在目录\glassfish-3.0\glassfish\domains\domain1\config中创建xml文件，并将端口号8080更改为任何其他端口，如以下行中的9999-

<network-listener name="http-listener-1" port="8080" thread-pool="http-thread-pool" transport="tcp" protocol="http-listener-1"/>

关闭文件，重新启动glassfish服务器，然后重新运行程序
